1. Earthquake Triggering
Earthquakes can talk to each other. Stress perturbation, as small as several kilo Pascals can cause the fault to slip and trigger an earthquake. Currently, I am very interested in the interaction between stress perturbation from nearby to remote earthquakes and volcanic/geothermal sites.
2. Earthquake Detection/Relocation
I have been working on extracting small missing events, by using larger cataloged events as "matched filters". This can normally result in 3-5 times more events, and lower the Mc by 0.5-1.0 unit. Particularly, events with nearly identical waveforms (so-called "repeating events") attract me.
3. Seismic/Aseismic Fault Slip
Stick-slip (seismic) and free sliding (aseismic) are two different end members of fault slip behavior. I am interested in exploring what's going in between. As a researcher majoring in observational seismologist, I am looking forward to bridge the "gap" using seismic tools. But I am never reluctant to try new stuff.
4. Lake Seismicity
After relocating to Michigan, I am starting to looking into the potential affect of the Great Lakes on local seismic activity. This is getting more fascinating since a ML4.0 earthquake struck the lake floor on June 2019, which is also during the "high water level" period within Lake Erie. Meanwhile, several PIs proposed to deploy a network composing 8 broadband stations along the eastern side of Lake Erie to listen to the seismic response of the Lake (LEEP experiment).
5. Dynamic Rupture Simulation
Strain (or stress) will be built up and released during earthquake cycles. I am interested to run some dynamic rupture simulation to understand how the stress evolves with time, and potential earthquake interaction. Specifically, we plan to build a model based on several foreshock studies, and to simulate the foreshock process and their interactions with mainshock.
