GaSm crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sm is bonded in a 7-coordinate geometry to seven equivalent Ga atoms. There are a spread of Sm–Ga bond distances ranging from 3.13–3.25 Å. Ga is bonded in a 9-coordinate geometry to seven equivalent Sm and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.63 Å.
The main objective of this study was the dynamic rupture modeling of the M7.3 1999 Chi-Chi, Taiwan earthquake. The purpose of the numerical modeling was two folded. First, using models of rupture dynamics, derive kinematic rupture characteristics, including spatial and temporal variations of the slip rate time history and rupture speed, in the long-period ground motion generation area (LMGA), strong motion generation areas (SMGAs) and background fault area for a thrust shallow rupture. Second, investigate the sensitivity of source time function characteristics in the LMGA and SMGA areas to model parameterization of low-velocity weak zone, such as thickness and shear wave velocity.
