我们研究了圣哈辛托断层带三叉区2000年后地震的位置、震级和断层类型，以阐明该地区地震破坏过程的基本方面。大多数M3.5地震具有走滑机制，发生在距主要断层（克拉克、巴克岭和Coyote Creek）1 km的范围内，震源深度为10- 13 km。相反，许多较小的地震在断层内深度超过13 km的区域具有正常的震源机制和震源。震源深度的其他小事件
We examine locations, magnitudes, and faulting types of post-2000 earthquakes in the trifurcation area of San Jacinto fault zone to clarify basic aspects of failure processes in the area. Most M3.5 events have strike-slip mechanisms, occur within 1km of the main faults (Clark, Buck Ridge, and Coyote Creek), and have hypocenter depths of 10-13km. In contrast, many smaller events have normal source mechanisms and hypocenters in intrafault areas deeper than 13km. Additional small events with hypocenter depth
