【摘要】 东源M4.8级有感地震发生后,广东省地震局地震现场工作队在震中附近架设了3个流动台,现场组网监测余震的活动。通过10 d的观测,不但记录了大量ML0.0级以上地震,还记录更多的ML0.0级以下地震事件。统计分析表明,此次地震属主震-余震型。流动监测不但提高了地震监测能力和定位精度,还向数字化烈度迈进了一步,为今后的烈度速报打下了基础。更多还原

【Abstract】 After Dongyuan M4.8 earthquake,three mobile stations have been set up near the epcintre by earthquake field work team of Earthquake Administration of Guangdong Province for monitoring aftershock activities.Through 10 days of observation,lots of earthquakes more than ML 0.0,as well as earthquakes less than ML0.0 were recorded.Statistical analysis shows that the earthquake belongs to the main shock-aftershock type.Through mobile monitoring,seismic monitoring capability and earthquake positioning accuracy are improved,and we have moved a step forward to Digital Intensity,which has laid a solid foundation of intensity report in the future.更多还原
