Fault2SHA 3rd Workshop: Role of scaling laws & fault interaction


Jul 2, 2018

The event gathered scientists working on earthquake hazards from a variety of perspectives: fault mappers, seismologists, hazard modelers, theoretical geophysicists, and engineers.The presentations by keynote speakers illustrated many challenges in understanding the distribution of earthquakes in time and space.


However they also noted that through careful data collection and analysis, progress is being made on important topics such as fault segmentation and earthquake clustering. In addition, the work by the hazard modelers shows that the constantly improving hazard engines such as OpenQuake and skills of the modelers are capable of dealing with the complexities of earthquake occurrence.


The group believes that the main challenges in estimating earthquake hazards lie in the scientific rather than technical aspects. Underscoring the value of openness and transparency, Richard Styron, GEM Active Fault Specialist says, “The level of communication and mutual interest was high among participants throughout the workshop, and there is widespread support for the creation of natural laboratories where observational scientists and modelers can share data and ideas, and test hypotheses, in an open and mutually supportive environment.”


The FAULT2SHA is a Working Group formally approved by the European Seismological Commission during its 35th General Assembly in September 2016. It is open to all researchers interested in contributing to discussions on topics that could improve the assessment of seismic hazard. For more information, please visit
