摘要
1986年8月22日11时3分在长白山西北约40公里的西土顶子发生M_s3.7级地震,震前在长白山天池地震观测站的测震、水氡观测中显示前兆异常。表明长白山区是一处地震前兆观测的敏感点。
At 11h03m07.5S on August 22, 1986, a MS3.7 earthquake occurred in Xitudingzi about 40 km northwest of the Changbaishan Mountain. Seismometry and radon-gas observation at the Tianchi (Heaven pool) seismological station in Changbaishan Mountain showed precursory anomalies before this event. The study shows that the Changbaishan area is a sensitive site for observing the earthquake anomalies.
