Source properties and rupture behavior

    I am interested in a broad spectrum of source properties and rupture behavior including determining the fundamental source directivity, understanding slow slip rupture, and exploring the seismic/aseismic triggering. A multiple seismic/aseismic slip behavior is found for Meinong earthquake, which implies complex and near-failure-state subsurface structure in southern Taiwan (Huang et al., 2016). Also, by stretching the source time function, we are developing a source inversion method that could simultaneous determine the moment tensor and directivity for intermediate-magnitude earthquakes, which has the potential to implement in real time (Huang et al., 2017).
