Workshop on Modeling Earthquake Source Processes

October 8-10, 2018
Caltech campus
1200 E. California Blvd. Pasadena, CA 91125

Contact us at or (626) 395-6919.

Thank you for your interest in the workshop. The deadline to apply for participation and travel support is June 15, 2018.

The goal of the workshop is to produce a white paper on future research directions that will enable substantial progress in modeling earthquake source processes, by coupling:
-- multiple temporal scales: dynamic rupture, interseismic period/earthquake sequences, short-term tectonics;
-- multiple spatial scales: shear zone/fault core, damage zone/deeper extensions, fault segment, fault network;
-- multiple physical and chemical factors: fluid effects, realistic geometry, inelastic processes.

Organizing committee
Jean-Philippe Avouac, Marine Denolle, Ylona van Dinther, Eric Dunham, Daniel Faulkner, Yuri Fialko, Michael Gurnis, Hiroko Kitajima, and Nadia Lapusta (chair)

To promote discussion and due to logistics, the workshop aims to attract 80 participants or less.  Limited funds are available for travel support, with priority for students, early career scientists, and invited speakers. 
To participate in the workshop and/or to contribute to the white paper, please apply by filling out the following online form by June 15, 2018:
The organizing committee will notify you about participation and travel support decisions by July 8; please do not make travel arrangements until you hear from us.

The workshop will be held at the Seismological Laboratory on the Caltech campus.

We have reserved blocks of rooms at a reduced rate of ~$200 per night including taxes in nearby hotels.  More details will be provided on July 8.
