| Abstract: | The fundermental principal and technique for earthquake focal mechanism (fault-plane solution) from compression and dilatation distribution of the first P motion data are presented brieftly. Take graphic technique as an example, the related physical idea and technique, are illustated step by step, to meet various needs (such as general understanding, study, applications, etc.) of various readers (such as students, teachers, disaster-managers, etc.) of various professional background (such as seimology, geophysics, geology, geodesy, engineering seismology, disaster-science, management science, etc.) |
