近年来,利用激光测量大陆板块运动、观测大地形变、监视断裂活动、记录岩石应变等,即利用激光测量距离的方法来研究地壳的变化,为人们提供地震前兆信息的工作逐渐得到开展。目前这些工作尚处于研究和收集资料的阶段,并未见到成功地预报地震,特别是预报离台站几千公里以外的强烈地震的三要素(发震时间、震中和震级)的报道。
In recent years, the use of laser to measure the movement of the continental plate, observe the deformation of the earth, monitor the fault activity, record the rock strain, that is, the use of laser distance measurement method to study changes in the crust, to provide people with earthquake precursor information gradually carried out. At present, these tasks are still at the stage of researching and collecting information, and no reports of successfully predicting earthquakes, especially the three elements of predicting strong earthquakes thousands of kilometers away from the station (epoch time, epicenter and magnitude) have not been reported yet.
