Nepal earthquake and 'panic'

The international community is now beginning to respond to the devastating earthquake in Nepal at the weekend. So far nearly 4000 people have been killed and over 6500 injured, with 4 million affected (although these casualty figures will probably rise as more remote areas are reached and the true scale of the damage is discovered). The media focus seems to be rightly shifting to the international aid response, and this is a welcome development, as not only are there thousands of people in desperate need in an already impoverished region, but again I would argue that the initial media reports of 'panic' are yet again not supported by events on the ground.

Media expectation of 'panic'
On 27/4/15, Radio 4's Today  programme included an interview with a British PhD student based in Nepal (interview begins about 2:14:40 into the programme). In it he explicitly rejected the notion when asked by the interviewer if there was 'panic' & instead focussed on how people cooperated with each other;
'while people were scared, I wouldn't necessarily call it panic... people were trying to help whenever they saw people in need'
This is supported by the image below of people helping clear rubble & rescue survivors in Kathmandu  and the general lack of police or military uniforms in the photo (I can only see one person wearing camouflage clothing) leads me to believe that there was general cooperation amongst bystanders in the aftermath of the earthquake- a concept known as 'zero-responders', that I have looked at in previous  blog posts.

'Panic' or evacuation?
Another more specific way in which panic has been used, also needs picking apart, as again I don't think it stands up to scrutiny. For example, there have been media descriptions of people 'panicking' as they fled buildings during the aftershocks, and there is quite an evocative video clip article, where BBC journalist Justin Rowlatt is caught in the middle of an aftershock and people fleeing buildings for open ground are clearly visible. However, he also rightly points out that 'earthquakes don't kill people, buildings do'. This is a basic tenet of safe evacuation behaviour during earthquakes, and seeing that the area where the earthquake happened is prone to such tremors, I would imagine that the local residents are familiar with such procedures. Therefore, far from being irrational 'panic', I would say that evacuating already weakened buildings during an aftershock is an example of sensible evacuation behaviour, possibly something that locals had learnt from previous education as to what is the safest behaviour in earthquakes. Another example of this is the photograph below of people evacuating a building in Lucknow, northern India, which is near the border with Nepal. Within the story that accompanies this picture is the following quote;
'Panic gripped people who came out of their houses, buildings, hospitals and shopping complexes to take shelter in open as they felt earthquake tremors'
However, from a more detailed look at the picture, I can't see expressions of fear on anyone's faces (some even appear to be smiling), and there doesn't seem to be any running or pushing that might be associated with a 'panicked' evacuation.

The Disasters and Emergency Committee has now set up an appeal for donations, and hopefully international aid will soon reach those affected by this awful tragedy. I am also relieved that media descriptions of 'panicked' reactions to the earthquake now seem to be receding, but I do wish that they wouldn't immediately jump into using the term, as it rarely matches up with people's actual behaviour and just perpetuates the myths about crowd behaviour that I and other colleagues in this field seem to spend so much time trying to unpick.

Aston Villa pitch invasion & moral panics

A recent FA cup Quarter final tie saw a pitch invasion by Aston Villa fans, as their team beat local rivals West Bromwich Albion by 2-0 at home, prompting media reports of a return to the 'dark ages' of the 1970s and 80s when pitch invasions and/or football related 'disorder' were common place. However, I would suggest that  closer examination of what seems to have happened during this incident shows such fears to be premature and somewhat alarmist. Furthermore, I would also argue that the reactions by match commentators and the general tone of media reporting of this incident reflect what I think is an ongoing moral panic not only about pitch invasions at football matches, but also of crowds in general (especially football crowds).

Historical contexts:
Pitch invasions have a long history at UK football matches (but are rarer these days) and were often associated with disorder. However, they don't always involve fighting between rival fans, and are more likely to be a celebratory response by fans to their team winning, and any interactions with rival fans are usually confined to ritualised behaviours (such as gesticulation, chanting, etc) rather than than overt physical aggression (see Geoff Pearson's work for detailed studies of football fans' behaviour & their treatment). However, football authorities (such as the FA and the Police) have tended to take a very dim view of such collective expressions  of celebration, and they often respond to them in a fairly robust way (see photo below of the police response at Villa Park).While they are technically illegal under the 1991 Football Offences Act, there are rarely enough stewards/ police to stop a determined pitch invasion (let alone arrest all those who take part in one!), and prevention usually relies on social pressure, with clubs, players, and commentators all queuing up to criticise such incidents in their aftermath- as happened this weekend .

Villa Park pitch invasion:
This particular game was perhaps likely to inspire strong emotions, seeing as Aston Villa and West Bromwich are local rivals from Birmingham, with their grounds less than five miles from each other. So, during stoppage time (and perhaps not altogether unsurprisingly),  the first of two pitch invasions by Aston Villa fans began, and prompted the following reaction from the match commentator Mark Lawrenson;
Why would you do this? You're winning, absolutely stupid. Loads of villages have lost their idiots tonight. Absolutely bonkers. 
Strong words, indeed. But in the televised footage, this first invasion appears to involve no more than 100 fans at at most, and the vast majority of fans seem to stay in the stands, with some booing those on pitch & gesticulating for them to get off- presumably because if the match had been abandoned at that point (with Aston Villa 2-0 up and very likely to win), the match would have had to have been re-played with no guarantee of them winning again. However, the second pitch invasion happened after the final whistle had gone, (meaning that Aston Villa were now through to the semi-finals), and involved many more Aston Villa fans (within a few seconds the pitch is full & large sections of the stands are now empty), suggesting that this second action was now broadly supported by the fans. The mood of the fans seems celebratory (rather than aggressive), and many of them surround the Aston Villa players to congratulate them and/or take their photos. Some of their behaviour may have been a little over-exuberant, but I can't see any footage that makes me think that anyone was under serious threat from the crowd (there's a Tweet that zooms in on footage of the assistant referee furiously running away as the pitch invasion happens, but the crowd appears to ignore him). However, the alarmist media reporting continued, as illustrated in how the BBC presented their interviews with Aston players afterwards. For instance, the following extract with goalscorer Fabian Delph was highlighted;
It was dangerous. Someone tried to take my boot off. People tried to kiss me and were biting me. It was scary
On its own, this suggests quite a scary situation, but if you go to the video footage where the quote comes from, you can see that Fabian laughs when he describes this incident, and doesn't seem to have been adversely affected by the experience- so it doesn't seem so serious when viewed less selectively in a wider context. 
Aston Villa v West Brom

Moral panics & their tragic consequences?
Finally, there are potentially deeper issues involved with this apparent moral panic over pitch invasions, with the most obvious, being that of the 1989 Hillsborough disaster where 96 fans were fatally crushed against metal fences designed to prevent a pitch invasion. In a previous post on Hillsborough , I highlighted the tragic irony raised by the Taylor Report into the disaster, that previous to Hillsborough, no one had ever died during a pitch invasion at UK football matches, but on 15/4/1989, 96 fans died in preventing a fictitious pitch invasion that never happened. UK football stadium design and safety procedures have come a long way since Hillsborough and such tragedies are thankfully very unlikely to happen again.  However, I worry that reports of pitch invasions that emphasise the 'irrationality' or even 'madness' of those involved, not only obscures accurate exploration of what actually happens, but also risks creating the space where irrationalist narratives of crowds could re-emerge into popular social discourse.

Shanghai crowd crush tragedy

New Year celebrations in Shanghai, China have ended in tragedy, with 36 dead and nearly 50 injured. It seems there was a fatal crowd crush about 20 mins before midnight, according to media reports. There has also been speculation in some coverage that the tragedy happened when people rushed forward to pick up fake money being thrown from the balcony of a bar into the crowd. However, I have seen this account disputed by others on social media, claiming instead that the crushing happened at a different location to the bar, and a BBC report also argues that the authorities in Shanghai were not adequately prepared for the size of the crowds on Shanghai's waterfront. I also saw an interview with a survivor in hospital who reported that people moving in different directions through the highly packed crowds caused crushing problems. So, I would suggest that crowd management failings may have been a more likely cause of the disaster. We shall have to see if more information emerges about this tragedy that helps paint a clearer picture of what actually happened, but yet again, the media's default response after tragedies such as these seems to be to blame the victims of crowd disasters rather than the authorities responsible for their safe management.

The BBC coverage quotes a photographer from the US who paints a bleak picture of people's behaviour;
"Nobody seemed to be in control and people were crying. It was one of those times when you see the worst in people."
However, no further description is given of any actual examples of what anyone was doing that illustrates 'the worst in people', and the very next quote used from another witness which describes spontaneous cooperation in the crowd appears to contradict this assertion anyway;
"Lots of people spontaneously linked hands to block the crowds, so the injured had space to settle down, and to allow a clear passage for ambulances,"

As I have argued in previous blogs, when disasters such as these happen, the term 'stampede' is almost always used uncritically by the media coverage to describe events, with all its negative connotations about crowd behaviour in such incidents- for instance that people are unthinking and/or selfish and trample over victims in their efforts to flee danger (for more details on why the term 'stampede' is problematic, see John Drury's excellent blog on the topic). Tweets I have seen from the crowd modelling expert Keith Still argue that the tragedy appears to have been caused by a Pressure Wave in the crowd resulting from a dangerous (but usually entirely avoidable) build up of crowd density, and he highlights that previous analyses of crowd disasters (e.g. Fruin, 1993) have concluded that;
'Virtually all crowd deaths are due to compressive asphyxia and not the "trampling" reported by the news media' 
Another study of a fatal crowd crush at a concert by the Who in the US in 1979 (Johnson 1987), found that survivors tried to help others that fell over, (rather than deliberately trampling them underfoot) and if cooperation did not happen, it was because people were physically unable to do so due to crowd density pressures. If trampling does occur, it is rare, and usually because of a domino effect in highly packed crowds (e.g. if someone falls over the physical pressure of the crowd can force others to fall on top of them)- not because people are 'stampeding' blindly without concern for others as they flee danger.   

Therefore, yet again I find myself repeating my call that we should stop using the term 'stampede' to describe tragedies such as the one seen in Shanghai, as it is not helpful in getting to the truth about what happens and may even distract from the apportion of responsibility for the tragedy, if as I suspect, it eventually turns out that crowd mismanagement was the cause. Such disasters are not inevitable and it is usually possible to prevent them occurring, providing there is adequate crowd safety management planning beforehand, and speedy responses are put in place to prevent crowd density reaching dangerous levels.  

Since I wrote the post above, the BBC have reported that Shanghai police now deny that fake money being thrown from a balcony was the cause of the tragedy, as this happened after the crush occurred (and the BBC has also largely removed references to 'stampede' in its coverage, and are now using the term 'crush' instead). Therefore, it seems increasingly likely that poor crowd management was instead responsible, and the casualties seemed to have resulted from dangerous crowding levels causing a wave of people to topple down a flight of stairs leading to a viewing platform. The Chinese President has ordered an investigation to examine whether there were enough police on duty to safely manage the crowds.

2014 review of the year

As the year draws to a close, it's time for another review of the highlights of my blog for 2014. This year I looked at public order policing in the UK, and how it is still being influenced by the fallout from the 2011 riots in England. There were also examples of public order policing abroad that showed similar patterns to that seen in the UK (perhaps reflecting similar ideological views towards crowds held across the world).I also looked at Ebola, and how specific aspects of the disease as well as the authorities' apparent fear of public responses seem to have influenced how national governments have responded to the outbreak so far. Finally I focussed on situations where crowd cooperation may become difficult if people are set in competition with each other. Many of these stories are ongoing, so I'm sure I'll have lots more to blog about in 2015!

Events close to home:
The year began with the announcement of the result of the inquest into the death Mark Duggan, (whose shooting by officers from the Metropolitan Police sparked 5 days of rioting across England in 2011), and I criticised the media for playing up the possibility of disorder after the result of the inquest- something that also happened before the result of Scottish referendum in September. I argued that while collective disorder in such emotionally charged situations is possible, it is far from inevitable, and that creating a climate where riots were expected, was not only irresponsible, but also makes it more difficult to conduct an objective examination of events in the aftermath of the comparatively rare situations when riots actually do happen.
The theme of public order policing continued in February, when there was a public consultation into whether the Metropolitan Police should be allowed to use water cannon the next time there was major disorder in the capital . I wrote a report that highlighted my concerns about its introduction to policing in mainland Britain (it is already used routinely in Northern Ireland): that water cannon was an indiscriminate tactic that would most likely escalate any disorder, and that there was a real risk of people catching hypothermia if it was used (especially if it was used in conjunction with the tactic of 'kettling' crowds). Authorisation to purchase water cannon from Germany was granted in June, and their use on British streets awaits final approval from the Home Secretary (which may be granted the next time there is serious disorder in the capital), and in a letter to the Evening Standard, I responded to Boris Johnson's offer to be hit by water cannon (I believe he has yet to follow through on this offer!), arguing that there were more serious issues at stake behind this publicity stunt.
Water cannon- coming soon to a riot near you? 

International contexts:
Over the late summer and autumn, I looked at public order policing further afield, and argued that there were issues involved that were similar to those seen in the UK. For instance, August saw prolonged rioting in Ferguson, Missouri in the US after an unarmed Black teenager (Michael Brown) was shot dead by local Police. I argued that the use of indiscriminate tactics (such as Tear Gas, stun grenades, sonic devices etc.) and the heavily militarised response to the protests was a major factor in the instigation and spread of collective disorder. I also suggested that it was necessary to consider the wider social contexts in which these protests occurred, and the worrying frequency with which African American males die at the hands of mainly white police officers, shows that the US still has a long way to go in addressing social inequality and the distrust and alienation that many local communities feel towards their police forces.
October saw the world nervously watching mass pro-democracy protests in Hong Kong, fearing a repeat of the bloody crackdown as happened in Tienanmen Square in 1989. Thankfully this did not happen, but the local Hong Kong Police did still display some quite forceful public order tactics at times. I highlighted an interesting historical coincidence that the current UK public order policing tactics were learnt from the colonial Hong Kong Police force after the riots seen in English cities in the early 1980s. So, it would have appeared slightly hypocritical had the UK government been too forthright in their criticism of the policing of the protests!

Public health emergencies:
This year saw 3 West African countries ravaged by Ebola, and I looked at how the authorities in the developed world have responded to this global public health crisis. I argued that the decisions in October by Australia to suspend visas to people from Ebola-hit countries, and the UK to introduce screening for Ebola at UK airports (by asking entrants from the Ebola zone a series of questions and taking their temperature) could be considered as examples of 'elite panic'. This was because such decisions went against expert advice and appeared to be done in response to pressure to be seen to be doing something and could have limited effectiveness in detecting Ebola. This seems to have been borne out by recent events, as Pauline Cafferkey (a Scottish nurse who recently returned to the UK after treating patients in Sierra Leone) contracted Ebola after returning home, despite having her temperature taken 7 different times before becoming unwell. The Chief Medical officer announced today (31/12/14) that screening for Ebola will be reviewed, although she emphasised there was still a very low risk of public infection, as Pauline was not displaying any symptoms when she travelled home (and people only become infectious in the end stages of the disease- which is why proportionately so many health workers in Africa have tragically died of Ebola).

Cooperation vs. competition?
Finally, towards the end of 2014, I looked at the issue of cooperation (or not) in crowds. A classic (although often untrue) cliché is that people will become inherently selfish in crowds- especially in stressful situations. The work that I have done on mass emergencies has found that this is rarely the case, and that people tend to behave cooperatively, because a shared identity often emerges from the situation which encourages such cooperation. However, in situations where people are cast in competition with each other for limited resources, then it may be more difficult for such a shared identity to emerge, and so cooperation may be less likely. I argued that the scenes witnessed at UK stores on Black Friday at the end of November illustrated this concept perfectly, and that retailers needed to be more responsible when planning for and hosting such events, as they had the clear potential to set people in competition with each other.

Boxing Day Tsunami 10 years on

Today the world is commemorating the 2004 Boxing Day Tsunami which killed up to 250,000 people, made millions more homeless, and devastated communities across South East Asia. I can remember how as news filtered in at the time about the scale of the shocking devastation across such a vast area, there were also heart warming reports of how these incidents can bring people together (a concept that has been noticed in research into other disasters- Solnit, 2008). For instance, there was an almost immediate international response to provide funds for the relief effort in the weeks after the Tsunami, and the Disasters and Emergencies Committee (DEC) raised nearly £400m from donations in the UK alone which was used mainly  to rebuild people's homes that were destroyed by the Tsunami. However, there were also more localised examples of co-operation in the tsunami zone. These are explored in more detail in the BBC's coverage of survivors' stories, but I will focus below on a couple of examples which I think illustrate quite well some of the psychological concepts which also emerged in the work I have done with colleagues on mass emergencies.

Co-operation amongst those affected seemed to be the dominant response in the acute situation once the Tsunami struck, and what I think is particularly interesting is that this seems to have been a universal response across the whole region. So for example, some of the areas affected (such as the East coast of Sri Lanka and West coast of Thailand) are popular with tourists from Europe, and as the Tsunami hit land there did not appear to any differences in co-operation between locals and tourists, with people helping each other regardless of who they were as illustrated by a British tourist who was on the beach in Sri Lanka at the time;
One of the only positives to come out of it all was the humanity of it. It didn't matter about your nationality or religion. Everyone was checking on each other.

This sense of co-operation was also re-iterated by a British couple who were close to land in a boat by the Ko Phi-Phi islands off the West coast of Thailand;

We all decided to stay on the boat that night, moored out at sea. The boat was too small to have taken us all the way to Phuket. The only option we had was to wait for help to arrive in the morning. It was the longest night of my life and were it not for the camaraderie of those passengers on board and the wonderful generosity of the Thai people who owned and manned the boat, it would have been unbearable. 

As the sun rose, we took the boat in to the harbour once again and waited for the larger boats to arrive. It was just awful. From our position on the water we saw hundreds of people all desperate to get off the island. They were huddled together on the pier in the harbour.

These quotes support the research we did with survivors of mass emergencies (Drury et al 2009a & b) that found similar accounts of co-operation during life-threatening emergencies, which we explained through the emergence of a shared identity which encourages co-operation rather than competition. However, the second paragraph does illustrate a potential situation where such co-operation could reduce once any unifying factors diminish. For instance, I heard of unconfirmed reports that some European tourists were fighting on the jetties to get on the boats that were leaving Ko Phi Phi the day after the Tsunami. I would suggest that if this did happen, then it could be because the immediate threat of death had perhaps diminished once the waters had receded, so the strong shared identity that may have been present during the immediate crisis phase when the waves struck, could have become less apparent. Therefore, it is possible that some people could have retreated back into previously held identities before the disaster struck and then began competing for what they perceived to be scarce resources (eg European tourists who want to go home, fighting for places on boats to leave the island- rather than people who face a shared lethal threat who need to co-operate to survive). My last post on the crowd behaviour during Black friday showed how people can behave competitively if they are cast against each other to gain limited resources, so perhaps a similar phenomenon was in play here as well. Finally, I would also say that it's worth emphasising that if any fights did occur, they did not appear to be representative of what was a generally co-operative spirit in the aftermath of the Tsunami, and some have even reported an enduring sense of identity with the region to this day- such as two British tourists who were holidaying in Khao Lak, Thailand at the time of the Tsunmai; 

Ten years on and we are still looking at life with a lot of more appreciation. We feel connected with Thailand so that is why we continue with a Thai animal charity.

'Black Friday' incidents are not necessarily crowd 'madness'

The phenomenon of 'Black Friday' seems to have firmly caught on the UK with reports of scuffles in the stores that participated across the country, and Police in Manchester have criticised Tesco for not being adequately prepared to deal with the crowds that gathered from midnight to pick up bargains. This is something I have been asked about by the media when previous events have created crowd management problems (such as the Ikea 'riot' of 2005), and the questioning usually goes along the lines of;
'don't these incidents disprove your theories as they show that people behave competitively and/or anti-socially in crowds?'   

My response is to say that the theories of crowd behaviour that I and others from my field use don't claim that people in crowds will always behave co-operatively and/or pro-socially, and they may even behave in ways that people today would find abhorrent (such as the racist lynch mobs that were common in the US before the 1920s). We would argue that the crucial factor in influencing a crowd to behave co-operatively or not is whether they have the opportunity to develop a shared sense of identity that can than lead to united action in pursuit of this common cause. The work I did with John Drury  into mass emergencies (Drury et al 2009 a&b) found that survivors of mass emergencies often reported a common identity with others in the crowd who may have been total strangers before the emergency began (eg 'we're all in this together'), and it was this shared sense of identity that meant that co-operative rather than selfish behaviour was often the norm in such situations.

What appears to have happened on 'Black Friday' however, is that far from encouraging co-operative crowd norms, people were instead encouraged to compete with each other. Such problems are exacerbated if stores open out of normal hours, and if any special deals are of a limited nature (eg 'the first 100 shoppers get a discount') as people can fear that they may miss out if they don't get there in time- which explains why crowd surges and even scuffles can break out in such situations. People behave in this way because they are being set in competition with each other, and there is much less of a chance for them to experience a shared sense of psychological unity. I explored a similar example of this when I looked at the fuel crisis in 2012, and I argued then that the media reporting people filling up their cars as 'panic-buying', as well as a government minister telling people to store petrol at home created a social dilemma, whereby people feared that if they did not stock up before others did, then they risked running out of petrol. However, this was what created the shortage, as there is not the capacity in the fuel distribution system for everyone to drive around with full tanks. What would have been an equally true (and more co-operative) message to present to the public would have been that there was sufficient fuel supplies & that they should not stock up if they didn't need to as that in itself could create a shortage.

So, I often find myself saying to the media that people don't necessarily descend into an 'irrationalist mob mentality' (a term I often hear journalists using to describe crowds) in such incidents, and that perhaps rather than asking why people can behave competitively in crowds, maybe instead we should look at ways in which we could encourage them to behave more co-operatively. I would argue that having events such as 'Black Friday' do not help encourage co-operative behaviour, and retailers should think very carefully about how they will manage such situations (or even whether they are justified at all) before advertising them. Furthermore, they need to take more responsibility for preventing the completely predictable (and often avoidable) crowd management problems that such situations can generate, rather than writing them off as examples of crowd 'irrationality'.

Zimbabwe 'stampede'

Reports are coming in that 11 people have been killed and over 200 injured at a religious service in a stadium in central Zimbabwe which seems to have happened after the event finished and people began leaving. There are also reports from local news that around 30,000 were attending the event, and as it finished, police forced attendees to leave through just one exit. Shortly afterwards people began pulling down a pre-cast wall (pictured below), presumably in an attempt to avoid what could have been severe over-crowding through a single egress point. It was after this, that the police are reported to have fired tear gas (a claim they currently deny), which then caused the 'stampede'. 

Yet again, I feel have to take issue with the use of the term 'stampede' (which has appeared in every report I have seen of this incident). As I have argued after previous fatal crowd crushes at religious festivals in India in February and October 2013, describing such incidents as 'stampedes' implies irrationalist and even animalistic crowd responses that are rarely supported by closer examination of what crowd members actually do, and concluded that crowd crushing is often more likely to be responsible for any casualties (as opposed to people being trampled by the fleeing crowd). Furthermore, using such terms risks deflecting the apportioning of responsibility for this tragedy  from the victims onto what appears on the face of it to be some woefully poor crowd management.  We shall see what further information emerges about this tragedy, but I do wish the media would stop using the term 'stampede' to describe such incidents as it hinders attempts to explore such events in detail and look at how they can be prevented in future.
