【摘要】 大多数火山口处的地震震源深度都非常浅,振幅也较小。因此,长白山天池火山地震监测台网的建设应满足以下三点要求。一要突出火山区小震和火山颤动的监测能力;二要突出火山地震与构造地震的分辨能力;三要考虑天池火山区的特殊地理环境特点。根据上述原则,分析在长白山天池火山区0～60 km范围内18个测震台站的布局及台网的监测效能,进一步为火山地震监测、预警、预报研究提供基础信息。更多还原

【Abstract】 Focal depths of majority of earthquakes at crater are very shallow and amplitudes are also small,therefore,Tianchi volcano seismic monitoring network construction should meet the following three requirements.First one is that the network must have monitoring capacity for small earthquakes and volcanic tremor in volcanic region.Secondly,network must have high resolution for volcanic earthquakes and tectonic earthquakes.Thirdly,the special geography of Tianchi volcano must be seriously counted.According to the requirements above,layout and monitoring performance of 18 seismic stations in range of 0～60 km range in Tianchi volcano of Changbai Mountain are analyzed,which will provides basic information for earthquake monitoring,early warning and prediction study.更多还原
