Research summary

I am a seismologist and this project is focused on the dynamic simulation of earthquake rupture.

Most of the earthquakes are caused by the faulting of rocks in the Earth's crust. Here we identify the rupture speed could passes continuously through the range of speeds between the Rayleigh and shear wave speeds (the so-called forbidden zone of rupture speeds) and eventually reaches compressional wave speed.

This work improves the understanding of the physics of faulting process, but also has very practical implications. Compared to subsonic earthquake, the supershear rupture earthquake produces stronger shaking farther from the fault and are richer in high frequencies.
