CascEff Project - the Role of Media in a Crisis: Leicester University

Leicester University is currently researching the role of media in the aftermath of crisis situations. The project comes under the European Commission's CascEff project. I am looking forward to seeing the results of the study when it is published.
The following is an extract from Leicester University's press pages:
Leicester researchers are examining how news coverage and social media activity during some of the largest disasters in recent years can help decision makers and incident managers prepare for future crisis situations.
Researchers at the University of Leicester’s Department of Media and Communication are contributing to a European Commission-funded project called “CascEff: Modelling of dependencies and cascading effects for emergency management in crisis situations”.
The project will examine the “cascading” effects of both natural and human disasters – where an initial incident can snowball, potentially threatening lives, property and the environment across large areas.
The Leicester researchers are looking specifically at how disasters are framed in both the mainstream media and by members of the public on sites like Twitter as events unfold.
They hope to identify examples of good practice for information dissemination to the public during crises. These will be used to develop a communication strategy for emergency services and incident managers to aid their preparation for future disaster events.
The researchers will examine: natural catastrophes, such as earthquakes and flooding; fires in buildings and tunnels; and outdoor events  such as pop concerts.
Examples may include the Tohoku earthquake and tsunami in Japan in 2011, the effect of hurricane Sandy on New York City in 2012 and the floods in South-West England last winter.
They also plan to look at news coverage of several earlier disasters, including the North Sea flood of 1953, the Sandoz fire and chemical spill in 1986 in Switzerland, and the fires which have broken out in the Channel Tunnel since its opening in 1994.
Dr Paul Reilly of the University’s Department of Media and Communication is leading the Leicester project. He said: “We hope this research will help emergency services in the planning of their communications strategies during crises.
“We will look at both social media and news media during these events, and how they can be used by incident managers to provide accurate, real-time information to members of the public. Clearly the immediacy of social media may have advantages and disadvantages for those involved in managing such situations.  Our focus will be on how key stakeholders can harness these tools to correct rumours and false information and to minimise the cascading effects of these incidents.
“The project will result in a report on the role of the media and the information flows that emerge during crisis situations, as well as a communication strategy which is intended to help decision-makers during future crisis situations.”
The Leicester team will consist of Dr Reilly and Research Associate Dimitrinka Atanasova, with this part of the project due to finish in December 2015.
The CascEff project also includes: SP Technical Research Institute of Sweden; Lund University, Sweden; the Swedish Civil Contingencies Agency; Ghent University, Belgium; INERIS (the French National Institute for Industrial Environment and Risks); KCCE (the Belgian Federal Centre for Civil Security); Safety Centre Europe; Université de Lorraine; Northamptonshire Fire and Rescue Service; and E-Semble, a Netherlands-based firm which makes simulation software for training safety professionals.

CRUST: Cascading Risk and Uncertainty assessment of earthquake Shaking and Tsunami

Bristol University's Faculty of Engineering have developed an interesting project on earthquakes and triggered tsunamis. The project is called CRUST: Cascading Risk and Uncertainty assessment of earthquake Shaking and Tsunami. I am looking forward to following the research outputs from this project.


The following extract is from Bristol University's Faculty news pages:




Building resilient infrastructure/communities against extremely large earthquakes is a global and urgent problem in active seismic regions. Economic consequences of natural catastrophes have become so devastating, reaching hundreds of billions of pounds in loss, and numerous mega-thrust events are anticipated to occur near vulnerable megacities around the world. The coordination on multiple, inter-related geophysical hazards (e.g. ground shaking and tsunami), analyses of which have been historically undertaken in a disintegrated manner, is needed. Although uncertainty is ubiquitous in natural hazards, treatment of uncertainty in risk assessment is fragmented. Improving the scientific understanding of hazard processes is crucial to better risk forecasting.


CRUST (Cascading Risk and Uncertainty assessment of earthquake Shaking and Tsunami) tackles the global challenge of modelling cascading hazards due to mega-thrust subduction earthquakes by developing a novel methodology for multi-hazards risk assessment from a holistic standpoint and by promoting dynamic and informed decision-making processes for catastrophe risk management. The scientific innovation of the CRUST project lies in a coherent treatment of risk and uncertainty related to compounding risks due to mainshock ground shaking, massive tsunami, and prolific aftershocks acting on coastal infrastructure. Creating a blueprint of the methodology and demonstrating it for several seismic regions are the goals of this project.


Specifically, the research objectives of CRUST are fivefold: (1) to develop an integrated multi-hazards impact assessment methodology for cascading earthquake-related phenomena (i.e. mainshock followed by tsunami and multiple aftershocks); (2) to characterise earthquake slips for future mega-thrust earthquakes as random field, and to evaluate the impact of uncertain slips on strong motion and tsunami simulations; (3) to model a sequence of mainshock-aftershock earthquake records based on actual observations, and to assess their combined effects on nonlinear structural response; (4) to model off-shore tsunami generation and propagation, to characterise tsunami fragility based on numerical simulations, and to validate these with a unique set of experimental data and field observations for the 2011 Tohoku earthquake and tsunami; and (5) to develop practice-oriented engineering guidelines and tools for multi-hazards impact assessment, and to demonstrate their capabilities by applying them to other subduction zones, such as the Hikurangi (New Zealand) and Cascadia (Canada) zones.

United Nations "Multi-hazard Disaster Risk Assessment" Conference

There is an upcoming conference on multi-hazards being held in China (15/09/2014 - 17/09/2014): United Nations International Conference on Space-based Technologies for Disaster Management "Multi-hazard Disaster Risk Assessment".


The following is an extract from the conference website:




Introduction



UN-SPIDER is the United Nations Platform for Space-based information for Disaster Management and Emergency Response, a programme implemented by the United Nations Office for Outer Space Affairs (UNOOSA). The UN-SPIDER Beijing Office is pleased to announce the “United Nations International Conference on Space-based Technologies for Disaster Management - "Multi-hazard Disaster Risk Assessment" from 15 to 17 September 2014.

The UN-SPIDER Beijing Office has successfully organised three conferences since 2011. Previous conferences covered the themes of “Best Practices for Risk Reduction and Rapid Response mapping” in 2011, “Risk Assessment in the context of global climate change” in 2012 and “Disaster risk identification, assessment and monitoring” in 2013. These conferences offered a forum for disaster management communities and experts to strengthen their capabilities in using space based information to identify, assess, monitor and respond to disaster risks and integrate space technology into long-term disaster risk management efforts.

 

Rationale

Recent disasters around the world have highlighted shortfalls in efforts of the governments and communities, including development partners, in reducing disaster risks. Although early warnings of hydrologic hazards (floods, storm surges, coastal erosion and droughts) and meteorological hazards (cyclones, tornadoes, windstorms etc.) are able to save human lives in some cases, the economic and environmental losses are often huge and recovery will usually take years to normalize. Therefore, countries need to have an increasing focus on economic, environmental and human costs of disasters and develop approaches to lessen the risks and reduce loss of lives and property.

All the elements of disaster risk are spatial in nature. Earth observation and geospatial data provide critical information on elements of risk delivered in the form of maps. These help in predicting and identifying risks more accurately as well as planning responses in a timely manner when they degenerate into a disaster.

Multi-hazard risks give an indication of the overall risk posed to a community. Multi-hazard approaches are valuable in providing an overview of the overall risk and thus enhancing effective planning countermeasures. Such approaches avoid enhancing further risks in the attempt to reducing already existing ones. The purpose of this conference is therefore to promote the role of space-based and geospatial information in a multi-hazard disaster risk assessment. It seeks to bring together experts and end-users to a single platform to ensure that space-based information is effectively employed in decision-making towards saving lives and reducing economic losses.

Conference Sessions

The conference will cover the following topics:


Session 1: Disaster Risk Management and Space-based information: This session will discuss experiences and good practices of disaster risk management at different levels, with a focus on the role and contribution of space-based information.


Session 2: Approach and methodology in using space based information in multi-hazard identification and risk assessment This session will discuss the applied research and development on the approaches, models, methodologies, tools, service platforms and operational projects related to multi-hazard identification and disaster risk assessment.


Session 3: Space-based information resources for hazard identification and risk assessment This session will discuss the space-based information advances in remote sensing data, information products, software used for multi-hazard monitoring, data visualization and data dissemination tools for disaster risk assessment.


Session 4: Space-based information for damage and loss estimation This session will discuss the methods and present case studies demonstrating the use of space–based information for disaster damage and loss assessment. This session aims to extend the scope of space-based information beyond emergency mapping, providing valuable information in damage and loss assessment.


Session 5: Networking and engagement with the UN-SPIDER network This session will aim at promoting the engagement of Member States and partner organisations with the UN-SPIDER Pprogramme. The session will discuss best practices of using space-based information and the impacts of the technical advisory support offered through the UN-SPIDER Programme.


Working groups

Working groups will be organised to discuss the cooperation related to disaster risk reduction mapping services and products, information sharing and cooperation projects in this area. The working groups will develop guiding points on ‘drought monitoring and risk assessment’ at the national level.

 

Target Audience

Disaster managers, policy makers, providers of space technology solutions/tools/applications from governments, academia, research, NGO and corporate sector. Number of expected participants: 120

 

How to apply and application deadline

The final deadline for registration was 29 June 2014.

Westwood Earthquake: Risk of Future Earthquakes-and-Landslides

At 13:25 UTC today on Monday 17th March a M4.4 earthquake occurred 9km NNW of Westwood, California, near to the city of Los Angeles. Whilst luckily no one was hurt, the earthquake serves as a reminder for those living within the region of the threat posed by the seismic faults beneath them. It is unknown or unreported at the moment whether any landslides or secondary hazards were triggered by the event. The epicentre of the earthquake is fairly close in proximity to the epicentre of the 1994 M6.7 Northridge earthquake which caused significant damage.


I am currently on holiday in San Diego at the moment, and hearing of the earthquake so close to me (in comparison to when I was in the UK) has prompted this blog post. My current research into earthquake triggered landslides has used the Northridge 1994 earthquake as a case study, investigating 'what-if' scenarios simulating the potential impact of such an event occurring in the present day. Unfortunately, I do not have my data or sources with me on holiday. But, I wanted to capture some of my thoughts on the event as soon as possible. I hope to update this post when I return to the UK for clarification and further details.

The area affected has been in a recent earthquake 'drought' with few earthquakes of significant magnitude occurring in recent years. The USGS suggest there is a potential for the recent M4.4 earthquake to be followed by another earthquake in the near future. Indeed, the entire region of Los Angeles is at risk of high magnitude earthquakes. The residents of Westwood and surrounding region are lucky the earthquake today was not of a higher magnitude and I can only hope this serves as a reminder for all those living in the region of the potential severity a bigger earthquake could cause.

There are currently no reports of landsliding in the area as a result of the earthquake. With a M4.0 the typically accepted threshold for triggering landslides, perhaps we may hear reports of landsliding coming in soon for more remote locations. The 1994 Northridge earthquake triggered tens of thousands of landslides in the surrounding region. Luckily, these landslides had minimal interaction with the population and infrastructure. However, where a landslide did affect a building, the damage from said landslide was approximately three times greater than the average damage caused by the earthquake shaking to similar buildings. Since 1994, there has been substantial development in Los Angeles, the San Fernando Velley and in the hillier areas surrounding Northridge.

Whilst I cannot go into specifics of the case study simulations I have run due to publication constraints, I can report that initial results suggest that even if the same earthquake occurred tomorrow as occurred in 1994 at Northridge, the potential impact of such an event would be greater than what was experienced in 1994. Even a smaller magnitude earthquake of, say, M6.0 could potentially cause as much damage as the M6.7 Northridge 1994 event, if it were to occur tomorrow. I will be able to give such statistics when/if the paper is accepted for publication in the near future.

The USGS PAGER estimates of losses due to secondary hazards states for today's event: "Recent earthquakes in this area have caused secondary hazards such as landslides and liquefaction that might have contributed to losses." This highlights a limitation of the PAGER loss estimates - the effect of secondary hazards are not currently accounted for in the report. This is an area the USGS is currently developing to be able to aid assessments of potential damage from the main shaking and secondary hazards for use in the future. Whilst secondary hazards such as landsliding do not always occur as a result of an earthquake, and in most cases, the majority of earthquake damages are caused by shaking, there are enough cases where the triggered landslides have caused a significant proportion of the damage to warrant concern. In some exceptional events, landsliding has caused the majority of losses as a result of an earthquake trigger. Development of a predictive tool for assessing landslide and liquefaction hazard and losses would be incredibly useful for emergency responders to get a more accurate picture of the disaster and locate areas of secondary hazard damage that may not be accounted for by earthquake shaking alone.

Whilst further research is required into the potential impact of secondary hazards, and the Southern California region provides an almost unprecedented amount of research and data to be of use in this area, I have respect and faith in the USGS and California research expertise in the area. From what I have learnt, California is one of the most regulated and highly prepared states for earthquake risk. By being located on active fault planes with high potential to experience the 'Big One' in multiple cities in the state, the officials and researchers have been forced to up their game. Whilst I hope that the region does not experience a high magnitude earthquake, the reality is that they are going to have one occur.

I hope the M4.4 experienced today has provided a timely reminder to all those living there of what they could face, and causes them to prepare and be able to respond appropriately if and when a future big earthquake comes their way.

Interacting UK Hazards - Impacts and Origins PhD

Loughborough University has recently advertised for a PhD opportunity: "Interacting UK Hazards - Impacts and Origins". It's great to see the field and funding is starting to get on board with multiple and interacting natural hazards!


Interacting UK Hazards – Impacts and Origins

Dr John Hillier, Geography, Loughborough
Dr Gregor Leckebusch, School GEES, Birmingham
Dr Kate Royse, British Geological Survey

Summary:
An excellent, inquisitive and highly-numerate student is sought to combine novel and industry-based GIS methods (i.e., catastrophe modelling) to understand the origins and impacts of interacting hazards as they afflict the UK.

Background:
The UK is affected by several natural hazards (e.g., floods in 2007). These are currently considered independently, but they could interact. A pilot study by the supervisors, using a novel way of examining past data, has robustly shown that interactions can alter likely ‘worst case’ losses by ~£50 million. This is of immediate interest to insurance companies and with much potential to contribute to policy making about the resilience of the UK as climate changes.

Objectives & Methodology:
A core of the work is low risk, building directly upon the pilot study, but scope exists for a student to innovate and excel. A key objective is to understand the origin of the interaction between shrink-swell subsidence losses for clay soils and other risks. This will be done by relating loss data (Zurich Insurance) to recorded weather patterns and developing published work linking subsidence and climate using British Geological Survey (BGS) data (e.g., GeoSure). The strength of interaction between physical processes required to explain the observed impacts will be quantified by generating catastrophe models [e.g., Donat & Leckebusch, 2011; Royse & Hillier In Press] (new QuickCat code). ‘Catastrophe modelling’ is relatively little used in academia, giving potential for exciting developments, and the last stage of this project is a new use for the technique.

Employability:
A secondment to Zurich Insurance Plc. (3-6 months) has been negotiated, and engagement with the BGS is anticipated. Catastrophe modelling underpins all financial risk assessment, and is becoming critical in Disaster Risk Reduction and humanitarian efforts, ideally placing the student for a range of careers. Training will include fieldwork, integrated modelling, GIS, and relevant programming giving the student skills identified as ‘most wanted’ for environmental jobs; ‘modelling’, ‘multi-disciplinarity’, ‘risk and uncertainty’.

EGU 2014: Multi-type hazard and risk assessment: Concepts and methodologies

Details of the 2014 EGU multi-type hazard and risk session for you all. Really disappointed I won't be able to attend this year. Once again, Kevin Fleming from the MATRIX project convening the session. Really nice to see this topic being pushed forward. Hope there are some good and relevant presentations for 2014!







NH9.9 Multi-type hazard and risk assessment: Concepts and methodologies

Convener: Kevin Fleming
Co-Conveners: Alexander Garcia-Aristizabal , Nadejda Komendantova

Losses arising from natural hazards are increasing worldwide, and are expected
to continue to do so, often as a result of the increased  exposure and vulnerability
of human society.  Scientists, engineers,  regional and local planners, civil
protection authorities and disaster  managers usually treat natural and
anthropogenic hazards and risks  individually; however, such a framework leads
to the neglect of the  frequent spatial and temporal relationships that exist between
hazards  and their associated risks.  This potentially leads to the situation where
simply summing the individual risks may result in an  underestimation of their true
impact, while identifying the different  types of risk, i.e., direct versus indirect, and
tangible versus  intangible, remains a challenge.  There is therefore an
increasing  realisation that a multi-hazard and risk framework is necessary if 
one is to effectively assess the consequences of natural and  anthropogenic
disasters, and to optimise the available resources for  mitigating against such
events.  Such a framework would need to consider  the various interactions
between different hazard types, and hazards  and risks, while also considering
the different loss types in order to  gain a complete view of how disasters impact
upon the broader society.

This session aims at presenting the latest developments in the area of  multi-type
hazard and risk assessment. The issues of particular concern  are cascade effects,
including the interactions between natural and  NaTech events, uncertainty
propagation and temporal dependency, which  requires examining short-term
sequences where hazards occur almost  simultaneously or are triggered by one
another, to longer-term scenarios  that may cover several months or years.  Case
studies where a  multi-type framework has been applied (for better or for worse) or
could  have been beneficially applied are also of interest.
