A REVIEW OF THE RESEARCHES IN THE BOHAI SEA EARTHQUAKE |
| |
| Abstract: | A series of researches and summationes of the 1969 Bohai Sea earthquake (7.4M_S)as well asthe precursory phenomena and the source environment have been carried out for twenty yearsby the earth-scientists of our country with great progress.We will present the results of the re-vised basic seismic parameters,the focal-mechanism and the focal parameters;the principalcharacteristic of the earthquake sequence;the fault-plane and the source environment(geophysical and geological conditions);and the main precursory anomalies.It is suggested thatthe Bohai Sea earthquake as well as its precursors will play an important role in the research ofprediction of earthquakes in China. |
