在台站少、台距大、地震小的情况下,如何发挥单台在监视震情中的作用,是值得探讨的课题.近十年来,国内已有不少人在这方面做了工作,并将几种方法逐步用于实践,取得一定效果,积累了不少经验.本文只对测震方面的几种方法作些介绍,以供台站的同志参考.一、单台测定震源位置单台测定震源位置,将为台站及时掌握当地地震动态,与群众业余队伍相结合,为开展预测预报提供依据.在地震活动区或靠近地震活动区的台站,单台往往记到很多微弱的地方性地震,别的台因台距大而记不到或记不好,故必须谋求使用单台资料测定地震参数方法.单台记到微弱的地方性小震,其特点是“近”和“弱”.因为“近”,震源深 In the case of few stations, large stations and small earthquakes, it is worth discussing how to play the role of a single station in the surveillance of earthquake conditions.In the past ten years, many people in China have done their work in this respect, And several methods are gradually used in practice, and achieved some results, has accumulated a lot of experience.This article only on the seismic measurement methods to introduce some of the methods for the station’s comrades reference.One single determination of source location single Taiwan determination of focal position, the station will be able to grasp the local earthquake dynamics, with the masses of amateur team combined to provide the basis for forecasting and forecasting.Seismic activities in the area or close to the seismic area of ​​the station, a single often remember a lot of weak For local earthquakes and other stations that can not remember or remember badly because of large stations, it is necessary to seek ways to measure seismic parameters using a single station. A single station records a weak local small earthquake characterized by “near” and “Weak.” Because “near”, deep source
