New research

Top 5 mega-earthquake hotspots New research from Aon Benfield and the Aon Benfield UCL Hazard Centre has identified the Caribbean, Cascadia in North America, Chile, Indonesia and Japan as areas where mega-earthquakes of moment magnitude (Mw) 8+ are most likely to occur. Aon Benfield’s, When The Earth Moves: Mega-Earthquakes To Come? report outlines the scientific assessment and addresses the re/insurance implications of a mega-earthquake in each region.

The five most vulnerable regions are:

Caribbean (Lesser Antilles) – The 2cm a year rate of plate convergence is enough to produce a mega-earthquake of Mw 9.0 once every 3000 years. A major loss in the Caribbean would quickly use up available reinsurance capacity;

Chile – As the only segment of the Chile-Peru Subduction Zone not to have ruptured within the last 100 years, the north Chile segment is now considered to be a region at high risk from an earthquake similar in size to the 2010 event. Following this year’s earthquake in Maule, reinsurance programs are now renewing with increases of 75% or more;

Indonesia (Sumatra) – Padang is now regarded as being at high risk from a mega-earthquake comparable to that which occurred in 1797, with a magnitude of 8.5 or more. A mega-earthquake would undoubtedly increase the price of reinsurance following a sizeable insured loss;

Japan – The South Japan Subduction Zone (Nankai Trough) has a complex pattern of three segments. The largest earthquakes rupturing along the whole subduction zone may have magnitudes of up to 8.6. A mega-earthquake in this region would most likely be a market-moving event;

North America (Cascadia) – The last mega-earthquake on this subduction zone occurred 300 years ago. While the short to medium term probability of a mega-earthquake may be low, insurers should not disregard the associated risks to the cities along the coast.

Previous earthquakes provide useful loss data for calibration of the catastrophe models, which remain a key tool for insurers. This will enable a greater understanding of their exposures and enable a more scientific approach to purchasing reinsurance.

Latest projects Aon Benfield partners with Cologne University on European windstorm Aon Benfield has signed an exclusive partnership with the University of Cologne – a leading research centre with a long record of windstorm diagnostics, extreme weather modeling and impact assessment – to advance research into European windstorms. The University of Cologne is the latest institution to join Aon Benfield Research, the academic and industry research collaboration.

The partnership is focusing on the following areas to input into models by Impact Forecasting, Aon Benfield’s catastrophe model development center of excellence:

introduction of output data generated by global climate models to extend the analysis period beyond the typical 50 years of meteorological records;

winter storms, the key hazard for most of western and central Europe, and in addition summer / hail storms where some countries in central and eastern Europe also face exposure;

how the losses of western, central and eastern regions correlate and impact the available capacity of reinsurance cover.

John Moore, International head of Aon Benfield’s Analytics team, commented: “Windstorms are a major driver of reinsurance purchases so this partnership is all about giving our clients access to the latest research and data in order to generate the most comprehensive loss estimations.”

Dr. Joaquim Pinto, senior researcher at the Institute of Geophysics and Meteorology from the University of Cologne, said: “Research on windstorm occurrence, their development and impacts have been the main focuses of our team. It is a pleasure to accept Aon Benfield’s Impact Forecasting invitation to coordinate efforts and combine state-of-the art scientific knowledge with risk modeling expertise.”

ETH advances tropical cyclone risk model ETH Zurich’s Risk & Safety Group has been developing a probabilistic tropical cyclone risk model, primarily comprising wind hazard modeling and portfolio risk assessments, in collaboration with Aon Benfield. It is being further improved by incorporating new insights of tropical cyclone events obtained using high-resolution regional climate models. In parallel, ETH is developing probabilistic flood and storm surge risk models for tropical cyclone risk analysis, using the indicator-based generic risk analysis framework of the Merci project (www.merci.ethz.ch<http://www.merci.ethz.ch/).

Kazuyoshi Nishijima at ETH Zurich said: “There are multiple benefits from the new research. For example, it will allow more precise tropical cyclone risk analysis of insurance portfolios and provide useful information on the tropical cyclone risks at different geographical resolutions, such as municipal or country levels. Moreover, the applied probabilistic methodology facilitates for updating of hazards and risks subject to near real time information concerning evolving typhoons.

These and other features of our recent developments will help decision makers to allocate resources for risk management in an optimal manner.”

The mid-term scope of the research is to combine risk models for individual hazards, such as wind, flood and storm surge, on a tool-platform for an integrated tropical cyclone risk analysis.

Seeds of a Bolivian project Dr. Stephen Edwards from the Aon Benfield UCL Hazard Centre (ABUHC) has completed three weeks in Bolivia for a risk reduction and climate change adaptation project.

In conjunction with CAFOD – the Catholic Agency For Overseas Development – the aim of the trip was to design a collaborative research project on risk analysis and reduction, based on development models and the impact of mega-projects.

Dr Edwards in Bolivia

Water risk was identified as the key theme, as all development models must be underpinned by responsible assessment and exploitation of water resources. Other issues investigated spanned from flood, drought and wildfire to water and food security, health and mining.

At the heart of European flood risk management HR Walllingford is contributing to two new European flood risk management projects, funded by the European Commission. FLOODProBE and UrbanFlood will advance European knowledge on urban flood risk management.

FloodProBE is addressing “Technologies for Improved Safety of the Built Environment in Relation to Flood Events”. The four year program started in November 2009 and researchers are aiming to provide cost-effective ways of reducing flood risk in urban areas.

The project will develop technologies, methods, concepts and tools for assessment purposes and to adapt new and existing buildings and infrastructure. It will:

improve methods for assessing the vulnerability to flooding of the urban environment, especially by extending conventional methods with the ability to assess indirect impacts of damage to networks and assets with a high value;

Aon Benfield Research 4

improve the understanding and assessment of urban flood defence performance in order to develop suitable protection measures and to increase the cost-effectiveness of future investments;

develop and test construction technologies and concepts to improve the performance of existing and new flood defences and for flood-proofing of the urban environment.

HR Wallingford is also working on UrbanFlood to investigate the use of sensors within flood embankments to support an online early warning system, real time emergency management and routine asset management. The project started in December 2009 and will run for three years.

The UrbanFlood project will create a framework that can be used to link sensors via the internet to predictive models and emergency warning systems.

Product launches TSR launches breakthrough hurricane tracking product Tropical Storm Risk (TSR) Business, which provides real-time mapping and prediction of tropical cyclone windfields worldwide and is co-sponsored by Aon Benfield, has launched a breakthrough product to help re/insurers estimate their potential wind losses for active hurricanes and tropical cyclones worldwide.

The new real-time product – the Ensemble Forecast Wind & Gust Swathe – comprises an ensemble set of 100 different forecast wind/gust swathes each with the same probability of occurrence. Re/insurers with access to a wind loss model will be able to calculate the impact on their portfolios of each outcome and thus the likelihood that portfolio wind loss will exceed different thresholds.

Professor Mark Saunders at Tropical Storm Risk said: “Considerable research underpins this new real-time forecast technology. The development recognises that wind-impact and wind-loss forecasts must be defined in terms of probability. Our approach, which models the forecast uncertainty of real events, provides an alternative perspective to the simulated event output of catastrophe models. With seasonal forecasts pointing to an active or very active 2010 hurricane season the release of this new product may be timely.”

Aon Benfield launches real-time catastrophe risk management tool Aon Benfield has launched ImpactOnDemand – a tool that allows re/insurers to visualize, quantify and connect their exposures to catastrophic events. Re/insurers can upload their portfolios for viewing and analysis, with the ability to plot a million risk locations in less than five seconds.

The web-based tool provides real-time information on catastrophes including earthquakes, hurricanes, wildfires, tornado and hail events, volcanic eruptions, and other ad-hoc events, allows for continuous exposure analysis.

Live data feeds from Tropical Storm Risk and EuroTempest, the leading resource for predicting and reporting on European windstorm activity, both of which are part of Aon Benfield Research’s academic collaboration, enable clients to use forecast and historical information to support claims and capital management processes.

I study earthquake hazard using geodetic data. The overarching goal of my research is a better understanding of the earthquake process through the applicatioinnovative data analysis and its assimilation into large-scale computation models of the fault syste

My original degrees were in civil engineering. I became interested in geology and earthquake physics, in particular, during my graduate work in California.

Firstly, earthquakes are a very compwe have learned a lot but much is still unknown. Today we are collecting more data about this obscure process than ever before, allowing usmake significant advances in our understanding.

especially earthquakes, is an area where we, as scientists, can have a direct impact on people's lives in a positive way.

Our group is working on a wide variety of including: an earthquake early-warning system usinintegrated GPS and seismic data; multi-scale models of natural earthquake fault systems; the development of innovative techniques for producing high-resolution radar images of the Earth's surface; studies of mining induced seismicity; and studies of earthquake hazard estimates using modern ground-shaking estimates

How will your work benefit the insurance industry?

A better understanding of the earthquake procand time-dependent earthquake hazard, in particular, wlocalized damage potential in regions of high seismic hazard. In addition, these estimatesused to provide urban planners and emergency hazard providers with information critical to mitigating damage and death before the occurrence of large events such as the Haiti earthquake.

What’s the most exciting future development in your field which could be of interest to

Early warning systems, which are currently being deployed and tested in areas of California and Japan, will allow up to a fewarning prior to large ground motions. This will allow for the rapid shutdown or closure of systesuch as gas lines and railways and the implementation of secondary backup systems.

What’s been your most memorable fie

At a conference on the Canary Islands in Spain,we toured the underground lava tubes on Lanzarote. The beauty and stillness of the tunnels was spectacular and awe-inspiring.

Where are you based and what makes this a great city?

I am based in London, Ontario in the Great Lakesregion of Canada, southwest of Toronto. A mid-sized city, Londwith a great selection of local, farm-raised produce and a wide range of outdoor activities, all within biking distance of a world-class research university.

Far more work needs to be undertaken, however, before we can get any sort of handle on how and to what degree, contemporary climate change will invoke a hazardous response.

To this end, researchers at the ABUHC and elsewhere are advocating a program of focused research in order to (i) understand better those mechanisms by which current and future climate change may drive hazardous geological and geomorphological activity; (ii) delineate those parts of the world that are most susceptible; and (iii) provide a more robust appreciation of potential impacts for society and infrastructure.

When our planechange, it is no

This has been most obvious over the last couple of millions of

global temperatures and sea levels as enormous masses of water are repeatedly locked up as ice at the poles and releases in liquid form back ithe ocean basins. During the course of such great environmental changes, the reaction oGeosphere has been expressed through theadjustment, modulation or triggering of a broad range of surface and crustal phenomena, including volcanic and seismic activity, submarine and subaerial landslides, tsunamis and landslide ‘splash’ waves, glacial outbursts and rock dam failures.

Such a relationship between climate change and hazards would be of academic interest and nothing more were it not for the fact that human activities are now driving climate change at a rate comparable to, or even exceeding that encountered at any time since the glaciers started their long retreat some time after 20,000 years ago. Worryingly, modelling studies aprojection of current trends point towardincreased risk in relation to a spectrum of geological and geomorphological hazards

in an anthropogenically warmed world. Meanwhile observations suggest that the ongoing rise in global average temperatures may already be eliciting a hazardous responsefrom the Geosphere, most notably in an increased incidence of giant rock and ice avalanches.
