Willis Research Network Seismic Risk Seminar

Willis Towers Watson would like to invite you to an afternoon of insight and discussion with the Willis Research Network (WRN). The event, which will be held in the London Lime Street Auditorium from 13.30 -17:00 on February 23rd, will be discussing trending topics on Seismic Hazard and Risk, and highlight opportunities for potential research directions that could trigger major advances and improve the way seismic hazard and risk is perceived, assessed and quantified in the Re/Insurance industry. We look forward to seeing you there.

Static Stress Triggering

Aftershocks can sometimes be larger or more damaging than their mainshock (e.g, Kumamoto and Christchurch). Static stress triggering acts over short distances (generally less than <200 km) and time periods from minutes to decades.

Introduced by Karl Jones, Head of Catastrophe Analytics at Willis Re International, Ross Stein, CEO and co-founder of Temblor.net, USGS Scientist Emeritus and Adjunct Professor of Geophysics at Stanford University, will discuss the cutting edge of static (Coulomb) stress triggering methodologies and real time aftershock forecasting.

Dynamic Stress Triggering

Recent research on Dynamic stress triggering has found new evidence on how earthquakes interact over long distances. Could this mean earthquakes can be linked many thousands of kilometres apart? This presents a challenge to the reinsurance principle that globally distributed earthquakes are independent.

Tom Parsons, from USGS, Menlo Park, CA and Emily Brodsky, from University of California, Santa Cruz, continue to pioneer research in the field of dynamic stress triggering. Introduced by John Alarcon, Executive Director at Willis Re Catastrophe Analytics, they will present the state of art and latest developments, as well as clear influences of global interactions on earthquake occurrence rates in specific regions.

Cybershake and 3D velocity modelling

The latest advances in computing now allow for 3D simulation of wave propagation; techniques simply not available to us previously. This will allow us to better understand the rupture of the largest earthquakes and in greater detail. How can this new method be used to better assess earthquake impact?

Introduced by Myrto Papaspiliou, Senior Earthquake Research Analyst at Willis Re Catastrophe Analytics, Kim Olsen , from San Diego State University, CA , will be presenting this pioneering technique with applied examples for the USA (CA - Los Angeles, UT - Salt Lake City, Cascadia subduction).
