【摘要】 为了解决河南豫北地区地震的定位问题 ,对豫北台网内的 10个典型地震 ,使用了 7个地震台站的资料 ,用波速比求出横波速度 ;用和达定位法 (有的同时使用高桥法 )进行了精确定位 ,求出震源深度 ;测量了震中至各台的震中距 ,以此反算出了纵波速度。通过计算 ,确定出了较为适合河南豫北地震台网地区的波速。更多还原

【Abstract】 The data of 7 seismic stations for 10 typical events occurred inside the seismic network of Northern Henan province are used for more accurate earthquake locating.The shear wave velocity is worked out with ratio of wave velocity,accurate locations are made with Wadati method(for some ones,Takahashi method also being used),focus depths are worked out and longitude wave velocity is inverted out by measuring distances from epicenters to each station.Based on the result above,a more reasonable velocity model is set up.更多还原
