Research

My research interests are in observational and theoretical studies of earthquake source mechanisms. In my previous studies, I worked on understanding how earthquake source properties vary with the earthquake magnitude using a unique massive data set from the Taiwan Chelungpu-fault Borehole Seismometers. Our study demonstrates significant increase in both stress drop and scaled energy for the magnitude range from 0.0 to 2.0, indicating that smaller and larger earthquakes have different kinematic and dynamic behaviors. The results also suggest the existence of a minimum rupture dimension for the micro-earthquakes that we have observed, pointing to the existence of an earthquake nucleation zone. To understand the physical basis for earthquake scaling, building simulated source models based on rate-and-state friction laws would be quite important. In particular, I would like to investigate the possibility that the events with unusual source properties are triggered, perhaps by natural fluid injections.
