The CIG Webinar Series draws from a pool of experts from mathematicians, to computer scientists, and to geoscientists, among others to bring together a cross-cutting community of faculty, students and researchers to both inform and disseminate knowledge on the tools and methodologies employed to further the study of problems in geodynamics.

The one hour webinars will be held the 2nd Thursday of each month October through May. Webinars will be recorded for later viewing. Reminders and details will be sent out through the cig-all mailing list.

Seismic Cycles Webinar Series

The Seismic Cycles Working Group presents this weekly seminar series in preparation for a virtual symposium this fall on seismic cycles modeling. The weekly seminar series will stretch until July 2022. Each week, we invite two speakers to give a 30-minute talk relevant to the following themes: 1) Physics-based foreshock and aftershock modeling: what can explain the observed rate of aftershocks and the possible origins of the Gutenberg-Richter frequency-size distribution. 2) The arrest and initiation of ruptures: what determines the size of an earthquake, the control of geometric, material, and dynamic heterogeneities on the frequency-size distribution and rupture style. 3) Modeling of slow slip and tremors: how to reconcile the time scales of slow-slip events and individual tremors and how to simulate the source mechanisms of tremors and low-frequency earthquakes. 4) Physics-based friction laws: what fault-zone physical processes must be incorporated, what are the important physical feedback mechanisms that operate across the seismic cycle, and what explains the evolution of effective friction parameters with temperature and water content. And finally, 5) Impact of fluids on the seismic cycle: what are the relevant chemical and physical processes connecting fluid injection (e.g., hydraulic fracturing) with induced seismicity, what is the role of poroelasticity.
All webinars begin at 9A PDT.
