S43E:
Earthquake Rupture Revealed by Kinematic Source Imaging I

Submit an Abstract to this Session



Session ID#: 32763

Session Description:
Large earthquakes exhibit great complexities. These earthquakes can involve multiple fault segments or multiple faults, and trigger large nearby aftershocks instantaneously. The complexity of large earthquakes stimulates developments of novel methods to map rupture evolution with multiple geophysical data sets. Combinations of datasets, such as seismic, geodetic and tsunami observations, have greatly improved the resolution of kinematic earthquake models and our understanding of earthquake rupture processes, but physics-based statistical approaches are needed to efficiently combine disparate data sets. Besides explaining multiple geophysical observations, quantifying source model uncertainties is equally important to identify robust features of the inferred rupture processes. We invite contributions related to kinematic source imaging, improved uncertainty quantification, and the combination of multiple datasets. In particular, we solicit studies that provide unified interpretations of observed earthquake kinematics with dynamic rupture simulations, post- and inter-seismic processes, tectonic setting, and laboratory experiments to reconcile observations over multiple scales.
