Multiple-Segment Rupture and Earthquake Probability in Fault System(1/3)

Project Details

Description

Several seismic events are attributed to ruptures on multiple seismogenic structures during coseismic periods. Their instantaneous ruptures along large structures patches generate earthquakes with large magnitudes, resulting in fatality and damage. Thus, this proposal aims to study on interaction between seismogenic structures, indicate potential seismogenic structures that could rupture instantaneously in a coseismic period, and assess probabilistic seismic hazard. For such purpose, triggering interactions between seismogenic structures will be discussed through both kinematic and dynamic models; earthquake probability will be evaluated using statistics-based, physics-based, and seismic statistical approaches. In order to evaluate their credibility, these models will be applied in the earthquake cases. Based on the multiple-structure system database summarized through this proposal and distribution of recent earthquakes, dynamic seismic hazard map platform that can be revised in real time will be proposed. The outcomes of this proposal will be beneficial to both other research projects and promotion of popular science.
