Voronoi图和双曲线联合方法在地震快速定位中的应用

Apply of Voronoi Diagram and Hyperbola Methods on Earthquake Rapid Location

摘要:

基于Voronoi图和地震震中近似满足双曲线分布,提出了一种联合应用V图和双曲线的地震预警快速定位方法。并对青海地震台网记录的地震进行了重新定位处理。研究结果发现,该地震定位方法能满足地震速报的精度要求,在时效性上也可满足地震预警的需要。该方法在地震预警方面有应用前景。

Abstract:

Based on the concept of the Voronoi diagram and distribution of earthquake conforming to the distribution of hyperbola approximately, a new methods for earthquake rapid location in the earthquake early warning is presented that using the V-diagram and hyperbola jointly. The earthquakes recorded by the digital seismic network of Qinghai province are relocated with the new method. The result shows that the new method can meet the need of location precision and the timeliness of rapid report in the earthquake early warning, and is better than other ways. So the method has a good prospect of application in the earthquake early warning system.
