项目摘要
The Scripps Institution of Oceanography of the University of California San Diego will prototype a new generation of sensitive motion detector of the earth. The fiber-optic-based sensors are deployed in deep boreholes and record movements as small as the width of a human hair over times that range from a fraction of a second to years. The new instrument package will record behavior from sudden earthquakes to slow movements that do not generate seismic waves. The instrument can be located where dangerous faults or volcanic hazards exist near human populations, as well as where induced earthquakes associated with fluid extraction or injection might occur. This project is aligned with NSF's mission of promoting the progress of science to advance the nation's health, prosperity, and welfare. The Scripps Institution of Oceanography will develop a geodetic/seismometer package that can detect a range of earthquake-related phenomena from sudden slip to continuous slow slip and episodic tremor. The package will provide key data for understanding the physics of fault movement. The robust fiber-optic-based sensors will have a long instrument lifetime and be resistant to high downhole temperatures. The comprehensive instrument will measure vertical and horizontal ground velocities, gravity, tilt, and strain. The prototype instrument will be installed in an existing borehole at the Pinon Flat Observatory for testing and comparison with existing seismic and strain systems. The new package is expected to significantly expand the network of geodetic/seismic observations both on land and beneath the sea floor.
加州圣地亚哥大学斯克里普斯海洋研究所将研制新一代灵敏的地球运动探测器原型。 基于光纤的传感器部署在深钻孔中,并记录从几分之一秒到几年的时间内小到人类头发宽度的运动。 新的仪器包将记录从突发地震到不产生地震波的缓慢运动的行为。 该仪器可位于人类附近存在危险断层或火山灾害的地方,以及与流体抽取或注入有关的诱发地震可能发生的地方。该项目符合NSF的使命,即促进科学进步,以促进国家的健康,繁荣和福利。 斯克里普斯海洋学研究所将开发一套大地测量/地震仪,可以探测一系列与地震有关的现象,从突然滑动到持续缓慢滑动和间歇性震颤。该软件包将为理解断层运动的物理学提供关键数据。坚固的光纤传感器将具有较长的仪器寿命,并能抵抗井下高温。 综合仪器将测量垂直和水平地面速度,重力,倾斜和应变。原型仪器将安装在Pinon Flat天文台现有的钻孔中,用于测试和与现有的地震和应变系统进行比较。预计新的成套设备将大大扩大陆地和海底大地测量/地震观测网络。
