中文摘要
该项目正在测量井下地震仪和应变仪上的噪音水平,这些仪器是作为地球望远镜板块边界观测站的一部分安装的。这些测量确定了数据在什么时间代表背景噪声,以及在其他什么时间发生异常信号。这些异常信号既包括小地震,也包括其他信号,如最近才观察到的阵发性震颤,这些信号很难与噪音区分开来。更好地测量这些信号对于了解安装了这些仪器的断裂带的行为非常重要。
英文摘要
This project is measuring noise levels on the borehole seismometers and strainmeters installed as part of the Plate Boundary Observatory component of EarthScope. These measurements establish at what times the data represent background noise, and at what other times anomalous signals are happening. These anomalous signals include both small earthquakes, and other signals such as episodic tremor, which has only recently been observed, and which can be difficult to distinguish from noise. Better measurements of these signals are important in understanding the behavior of the fault zones around which these instruments have been installed.
