摘要:
利用云南测震台网记录的汶川MS8.0地震及其余震序列共28个数字地震波形,对MS≥6.0余震进行波形特征分析、MS≥5.0余震进行地震定位分析。根据主震波形分析结果,汶川8.0级主震有别于其它余震。比较四川台站和云南台站的定位结果,云南测震台网的地震定位精度与台站布局关系密切。
Abstract:
We analyze 28 waveforms of the Wenchuan MS8.0 earthquake and the aftershock sequence recorded by the Yunnan seismic network,and give the waveform characteristics of MS≥6.0 earthquakes and the location results of MS≥5.0 earthquakes. The analysis of the mainshock waveform shows that the mainshock is obviously different from the aftershocks. Comparing the location result of the Yunnan seismic network to that of the Sichuan seismic network,we find that the accuracy of the former's location is closely related with the distribution of stations.
