Abstract

Abstract: In order to obtain reliable the source parameters quickly, such as focal mechanism solutions for mid-strong earthquakes, an interactive inversion software based on CAP method is designed and implemented. The software has a graphical interface to read the earthquake waveform from regional seismic network. Stations used for inversion are selected by user. Then the software can be used to automatically process the observed waveforms, calculate the theoretical Green's function and invert the focal mechanisms of the earthquakes. It is proved that the software is convenient, reliable and robust by testing multiple earthquakes with different tectonic environments, different magnitudes and different types. The software is easy to quickly obtain focal mechanism solutions of the intermediate or strong earthquake. It is significance to provide the solutions data for emergency response, and it is beneficial to the study on seismic source properties.

Key words: Focal mechanism, CAP method, Interactive inversion software, intermediate or strong earthquake
