| 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. |
