The primary goal of this research is to use the concept of the strongest intersections of the circular arcs of earthquakes to predict the future strong earthquakes. Filtering down the seismic data through earthquakes of magnitude 6 ,when five points are approximately uniformly distributed along an arc ,it is called the strongest circular arcs of earthquakes. This thesis aims to find out the strongest intersections of the circular arcs of earthquakes and use statistics to analyze the strong events happen near the intersections, and try to find the connection between them.
The analysis of the intersections of the circular arcs of earthquakes was developed from the concept of stress concentration in crust and the strongest intersection of the circular arcs of earthquakes is named by Professor Hin-Chi Lei.
The purpose of the study focuses on the earthquakes in Japan area, from 1995 to 2004, recorded in seismic data of Japan Meteorological Agency. We have found 13 strongest intersections and 7 strongest double intersections of circular arcs of earthquakes . For every case , in the circular predicted region with the radius equalto the quarter of the smaller arc length of the intersections, at lease one magnitude 5.7 earthquake can be found within 3 years after the formation of the strongest intersection of circular arcs of earthquakes .This result confirms the connection between the strongest intersections of circular arcs of earthquakes and the strong earthquakes happened after them.
