Although there is profound evidence that pre-existing socio-economic conditions greatly influence the recovery process after an earthquake, attempts to measure and validate this relationship have been limited. As a result, GEM is investigating the relationship between disaster resilience and earthquake recovery through a novel framework, according to which socio-economic indicators are used to predict the evolution of recovery of the building stock following an earthquake. The city of Napa, California and the 2014 South Napa earthquake are being used as a case study for the development and validation of the aforementioned methodology (click on the title to read more).

A number of approaches for understanding earthquake risk exist, but it is the interrelationships between these concepts that are becoming the focal point for politicians, stakeholders, and the general public (click on the title to read more).
