%X 地震定位是地震学中一个最基本的研究内容，对于研究地震活动特性、地球内部结构、震源的几何构造等地震学中的基本问题均具有重要意义。但是直接计算获得震源位置信息和发震时间计算量较大，且不易实现。在本研究中，我们通过MABLAT实现了INGALADA方法定位以达到确定震源位置与发震时刻的目的。该地震定位方式可以实现非专业人士，不需要操作人员掌握深厚的计算机和数学知识便可以通过直接获得站台P波、S波的实际到时和台站的位置数据导入设计好的GUI展示界面中由于GUI界面具有便利性和直观性，可以让非专业人士直接获得INGALADA算法计算出的震源位置和发震时刻。地震定位可以提供一些重要的地理位置信息便于研究地质结构，对地震的研究发震有着重大的意义。<br />
Earthquake positioning is one of the most basic research contents in seismology, and it is of great significance for the study of the characteristics of seismic activity, the internal structure of the earth, the geometric structure of the source and other basic issues in seismology. However, direct calculation to obtain the source location information and earthquake occurrence time requires a large amount of calculation and is not easy to implement. In this study, we implemented the INGALADA method positioning through MABLAT to achieve the purpose of determining the location of the earthquake source and the time of occurrence. This earthquake positioning method can be realized by non-professionals. It does not require the operator to have a deep computer and mathematics knowledge. It can directly obtain the actual arrival time of the station P wave, S wave and the position data of the station and import it into the designed GUI display interface. Due to the convenience and intuitiveness of the GUI interface, non-professionals can directly obtain the source location and time of earthquake calculated by the INGALADA algorithm. Seismic positioning can provide some important geographic location information to facilitate the study of geological structure, and is of great significance to the study of earthquake occurrence.
