Fluid induced aseismic fault slip: how much we can learn from earthquake swarm and repeating earthquakes? Earthquake swarm and repeating earthquakes are part of the spectrum of aseismic processes that release tectonic stress at depth. Their episodic occurrence in subduction zones has been regarded as an important indicator for stress and fluid pressure cycling. Whether the characteristics of fluid generation and migration is different at different tectonic regimes, and how do they influence earthquake cycle however, remain elusive. The active collisional mountain belt in Taiwan provides an unique opportunity to study the association between fluid-flow system and their impact on various earthquake behavior. Does pore-fluid migration serve as the common generation mechanisms for these three seismic phenomena? In this intern program, you will learn how to (1) search for magnitude greater than 2 swarm and repeating earthquakes in southern Central Range and (2) relocate the earthquakes to extract the possible migration behavior. By quantifying and relocating the aseismic slip driven earthquake activities, we hope to better understand the role of fluid in aseismic slip processes underneath the mountain belt.
