Biography
I am a Research Fellow at the Earth Observatory of Singapore (EOS)/School of Mechanical and Aerospace Engineering (MAE), NTU, Singapore.
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.
Research focus: Earthquake cycle modeling, Laboratory friction experiments, Observational seismology
