Physics Based Modeling of the Earthquake Cycle. Do Observations Matter?
Session ID#: 78354
Session Description:
During the last decades, our ability to document recent earthquake ruptures using field-based and remotely sensed observations has significantly increased both in quality and quantity, providing an increasingly detailed view of complex earthquake rupture patterns and earthquake cycles. At the same time, our capacity to construct ever more sophisticated (and often physically realistic) numerical models of earthquake ruptures and earthquake sequences has boomed. Hence, paradigms are shifting and a new vision of the earthquake cycle is emerging, which incorporates complex data to better reproduce and understand earthquake rupture processes.
In this session we welcome contributions presenting new data that improve our understanding of earthquake rupture and cycle, from seismology, geodesy and earthquake geology, as well as results from numerical simulations to gain insight into more realistic physics-based earthquake rupture and cycle behavior.
