| Abstract: | In this assay, the recording characteristics of earthquakes in Chile recorded by Wenzhou Seismic Station is analyzed, and the analytical method is also introduced in detail. It is found that if the epicentral distance of earthquakes in Chile equals 168 degree, the diffracted waves of PDIF seismic phase can still be recorded clearly. The recorded characteristics of the waves turn out to be single with gentle slope in the beginning and long period. Using the arriving time of obvious seismic phase such as PDIF, PKP, SKKS, SS to report the earthquakes rapid- ly is helpful to improve speed and quality of rapid reporting. |
