Table 1. Parameters of each layer in the 3D velocity structure model. The sediment-bedrock interface z varies station by station. r1 and r2 represent the common proportionality constants of Kagawa et al. (2004).

From: Analysis of the rupture process of the 1995 Kobe earthquake using a 3D velocity structure
