I am interested in various rupture styles, particularly slow slip preceding fast ruptures. I have used the phenomenon of slow and fast ruptures on a single fault patch to explain the mechanism behind the period-doubling tremors near Parkfield, deep beneath the San Andreas Fault (Veedu & Barbot, Nature, 2016, https://doi.org/10.1038/nature17190).
I recently published a work to understand why the northern Cascadia and the Nankai regions produce irregular slow-slip events whereas Japan, Chile, and the Middle American Subduction zones generate both slow slip and ordinary (fast) earthquakes in a single location. We provide solutions on such behavior of slow slip and earthquakes using laboratory experiments and numerical simulations (Veedu et al., Geophys. Res. Lett., 2020, https://doi.org/10.1029/2020GL087985).
Currently, I am extending my work to a range of slip behaviors using finite-fault fully dynamic numerical simulations to construct an elaborate phase diagram by collaborating with Caltech.
I dwell on several fascinating topics:
• Can a simple model explain a variety of earthquake and slow-slip observations in nature?
• How can we better understand the phenomenon of slow-fast ruptures using finite-fault simulations and laboratory experiments?
• Does a fault system transition though chaotic sequences before entering into dynamic earthquake regime?
