| Research Abstract |
Analyzing a borehole core across the fault zone which includes detailed 3D structure of the fault, we constructed a 3D underground fault model. We found that the obtained fault model is quite similar to that of the 2008 Sichuan, China, earthquake, although their scale is different. Therefore, we investigated the fault rupture process based on the 3D fault structure obtained in the borehole core. We found that during the Sichuan earthquake, the fault rupture propagated simultaneously along two parallel fault segments.
