Problems solved by technology

The epicentral distance obtained by empirical parameters in the current epicenter location method has poor accuracy. The existing wave velocity travel time method assumes the same wave velocity. This method assumes that the P-wave velocity of the formation is constant. Therefore, a method that considers different soil layers, The space-alienated wave velocity traveltime fast epicenter location method proposed by the difference of wave velocity in the crustal layer improves the accuracy of epicenter location

Description

technical field [0001] The invention relates to the field of earthquake early warning, in particular to a method, device, equipment and readable storage medium for determining the location of an earthquake epicenter. Background technique [0002] Earthquake is a random and extremely destructive natural disaster. The earthquake early warning system is mainly realized by the speed difference between P wave and S wave. The epicenter location is a key parameter in the earthquake early warning system. On the one hand, it affects the accuracy of magnitude estimation, and on the other hand, it also affects the accuracy of the earthquake early warning disposal range. The epicentral distance obtained by empirical parameters in the current epicenter location method has poor accuracy. The existing wave velocity travel time method assumes the same wave velocity. This method assumes that the P-wave velocity of the formation is constant. Therefore, a method that considers different soil ...
