ABOUT ME
| My research focuses on exploring the mechanics that drive seismic swarms. The exact role of “aseismic” slow fault slip versus fluid migration in seismic swarms is controversial, and a more deterministic framework of understanding for fault ruptures is desired. To test the drivers of seismic swarms, I start from a pure geodetic perspective, and later expand it to incorporate more seismic data to refine the timing of fault movement. I am also interested in whether the same physics learned from small-to-moderate earthquakes control sequences of moderate-to-big earthquakes. |
