| Research Abstract |
Ground motion generated by buried rupture earthquake is empirically larger than that generated by surface rupture earthquakes. I focus on a relation between a hypocenter depth and bottom depth of seismogenic zone in a crust, and perform physics-based rupture simulations numerically. For the buried rupture earthquake, pulse-like rupture becomes major. That causes seismic radiation energy be compact in time.
