T31B:
Earthquake Rupture Processes: Confronting Field Observations and Models Posters

Submit an Abstract to this Session



Session ID#: 25767

Session Description:
In recent years, combined progresses in our understanding of earthquake mechanics and computation capabilities have allowed to develop numerical models that address earthquake mechanics at a variety of scales, from fault segmentation to co-seismic off-fault damage.

These theoretical progresses can potentially suggest new observations that can be tested by field or geodetic studies. In parallel, innovative technics in earthquake geology and active tectonics have allowed for a significant improvement in our capacity of detailed observation of earthquake ruptures. Hence, it is time to confront high-resolution observations with numerical and theoretical models to test these models and see in which direction observation should go. We welcome contribution testing earthquake mechanic models based on observational data (geodesy, field data…) as well as contribution suggesting new potential field observation, based on theoretical or numerical developments.
