RAPID - Response to the Increased Seismic Activity along the San Jacinto Fault Zone Following the 4 April 2010 Mw 7.2 El Major-Cucaph Earthquake

2010年4月4日复活节星期日，发生了里氏7.2级的埃尔梅杰-库卡巴地震，破裂始于库卡巴山脉南端的下加利福尼亚州，向西北方向传播，并在余震集中在加利福尼亚州边界以北的地方终止。自从发生7.2兆瓦的埃尔梅杰-库卡巴地震以来，地震活动一直向北迁移，其中包括最近的2010年7月7日柯林斯山谷5.4兆瓦地震。这一快速奖励将加快现有国家科学基金会资助的项目(EAR-0908903)的仪器部署，该项目名为：沿圣哈辛托断裂带的合作研究：结构建筑和演化板块-边界过程。这是南加州大学、加州大学圣地亚哥分校、圣地亚哥州立大学和联合国志愿人员组织联合开展的项目。这一快速项目将利用联安部队的资源，为安装新的浅井传感器提供最具成本效益的方法。这笔资金仅用于浅孔钻探，因为南加州大学提供钻孔传感器，加州大学圣迭戈分校提供数据采集系统。这笔快速资金将允许安装7台。

On Easter Sunday, 4 April 2010, the Mw 7.2 El Major-Cucapah earthquake occurred with rupture initiating in Baja California at the southern end of the Cucapah mountains, propagating to the northwest and terminating where the aftershocks concentrated just north of the California border. Since the Mw 7.2 El Major-Cucapah earthquake there has been a migration of seismicity to the north that has included the recent 7 July 2010, Mw 5.4 Collins Valley earthquake. This RAPID award will accelerate the instrument deployment for the existing NSF funded project (EAR-0908903) entitled: Collaborative Research: Structural Architecture and Evolutionary Plate-Boundary Processes along the San Jacinto Fault Zone. This is a joint project between USC, UCSD, San Diego State University, and UNAVCO. This RAPID project will use resources of UNAVCO to provide the most cost effective method for installation of new shallow borehole sensors. The funds are solely for the shallow borehole drilling, since USC is providing the borehole sensors and UCSD is providing the data acquisition system. The RAPID funding will allow for 7 installations.
