加州工学院所用自动氡、钍监测器的位置示于图1。四个台站位于该断层大“拐弯”附近。圣安德烈斯断层自1857年的提宗堡地震以来,应变日益积累。其它台站位于横向山脉断层前沿。Melvin 等(1978)描述过监测系统的设计及其使用方法;从监测开始(1977),在一些小的当地地震前,可观测到氡异常;在两个断

The location of the automatic radon and thorium monitor used by the California Institute of Technology is shown in Figure 1. Four stations are located near the corner of the fault. St. Andres Fault Since the 1883 Tyuzzo earthquake, the strain has accumulated. The other stations are located at the forefront of the transverse mountains. Melvin et al. (1978) described the design of monitoring systems and their methods of use; from the beginning of monitoring (1977), radon anomalies can be observed before some small local earthquakes;
