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.

2010年4月4日复活节星期日，埃尔马约尔-库卡帕地震发生了7.2级，破裂始于库卡帕山脉南端的下加利福尼亚，向西北传播，并在加州边界以北的余震集中地终止。自El Major-Cucapah 7.2级地震以来，地震活动向北迁移，包括最近的2010年7月7日柯林斯谷5.4级地震。该RAPID奖将加速现有NSF资助项目（ESTA-0908903）的仪器部署，该项目名为：合作研究：结构体系结构和沿沿着圣哈辛托断层带的演化板块边界过程。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UNAVCO之间的一个联合项目。 这一快速项目将利用联合国难民事务高级专员办事处的资源，为安装新的浅井传感器提供最具成本效益的方法。这些资金仅用于浅井钻探，因为南加州大学提供钻孔传感器，加州大学圣地亚哥分校提供数据采集系统。RAPID的资金将允许安装7个装置。
