THE FAULT2SHA EUROPEAN SEISMOLOGICAL COMMISSION WORKING GROUP: AN ATTEMPT TO LINK FAULTS TO SEISMIC HAZARD ASSESSMENT

Bruno PACE and the FAULT2SHA Working Group

 

Università degli Studi di Chieti-Pescara, Disputer Department, Chieti, Italy

 

The objective of the Fault to Seismic Hazard Assessment (Fault2SHA. fault2sha.net) Working Group is to build a community of active fault-related researchers to exchange data, tools and ideas on how to best model faults in seismic hazard assessment in specific tectonic contexts. After a few meetings (Paris 2014, Chieti 2015) and thematic sessions at international Conferences, the WG was officially established inside the European Seismological Commission (ESC) in 2016. Being a not-funded entity the WG acts on a voluntary basis. The community involved is made of data providers, data modelers and data users willing to share data and methodological approaches. Given that in 2016 numerous Fault2SHA members signed-up, an Executive Committee was elected in 2017 to coordinate actions within the WG and to actively look for funding. A Fault2HA-Betics WG is today federating the Iberian Peninsula earthquake geologists; we are now opening to the Americas, in order to link the “New” and “Old” Worlds and build an international collaborative network of people committed to pooling their experience and insights that enhance the Fault2SHA WG capacity for effective actions.

The WG milestones achieved since 2016 are: a paper on aftershock probabilistic seismic hazard based on fault data gathered by many European teams in the wake of the Amatrice, 2016 M6.0 earthquake; the organisation of an international workshop in Barcelonette in 2017, that gathered 50 participants from around the world; the publication of 10 papers in a special issue of the NHESS journal; the organisation of a training course in Paris in 2017, where geologists learned how to use some Fault2SHA tools. 

The WG has initiated other collaborative initiatives such as the establishment of natural laboratories in Italy and Spain. Preliminary results have been recently presented at SSA. In these laboratories we want to address specific issues and questions such as: Methods to define sections/ruptures; Physics-based approaches; Need for the collection of data (volcanic area?) to update scaling laws; How to constrain slip on faults using geodesy? How to propagate uncertainty in fault-PSHA? 

The Fault2SHA presentation at USGS is an additional opportunity to widen the discussion beyond the European context and to open to new potential members the opportunity to join us at the next ESC meeting that will be held in 2018 in Malta.
