地震预警中的单台综合定位方法
A INTEGRATED SINGLE-STATION SEISMIC LOCATION METHOD FOR EARLY WARNING
【摘要】 基于日本基盘强震观测网中某个地震事件首个地震台记录的震级在4级以上、震中距为30~100 km的强震数据,运用B-Δ法和Voronoi多边形法相结合的方法计算震中距。结果表明,B-Δ法和Voronoi多边形法相结合计算出的震中距与单用B-Δ法的计算结果相比,单台定位所用时间相同,但其定位精度明显提高。
【Abstract】 From the strong motion data at the first station which received seismic signal of a certain event downloaded from KIK-net of Japan,whose magnitude are more than 4 and epicentral distance range from 30 km to 100 km,we computed the epicentral diatance with the combined B-Δ method and Voronoi polygon method.The results show that with the combined method and the calculated epicentral distance can be more accurately than with only B-Δ method as consune the same location time.
