| 摘 要： | 2001年3月7日在四川省凉山州布拖县境内发生Ms4.6级强有感地震，震中位于北北西走向的凉山断裂南段，邻近则木河断裂，分析认为，这是一次主震-余震型地震序列；进一步用西昌满腔遥测地震台网各子台的P波初动求得主震和最大余震的震源机制解，认为它们可能是北北西走向的凉山断裂活动的结果。

| Abstract: | An Ms4 6 Earthquake On 7 March 2001,which was intensively sensed by the local people,occurred in region of Butuo County,Sichuan province.The epicenter of this earthquake is located in the southern part of Liangshan faults with NNW trending and it is near to the faults of Zemuhe.We studied the seismic sequence data and find that the type of this earthquake is the main shock-after shock type.We use the first movement data of P wave recording from the seismic monitoring network of Xichuan to analyze the focal mechanism solution and consider that the earthquake may result from the activity of the faults of Liangshan. |
