Teleconnection between Great Earthquakes in Japan and Moderate-Strong Earthquakes in China and Its Vicinity

We quoted total 67 seismic events of M_s=6.9-9.0 in past 110 years (during 1900 to March 2011) in five divided regions from north to south in Japan and total 569 moderate-strong earthquakes of M_s≥6.0 in China and its vicinity to study their correlativity. The corresponding comparison was carried out to compare each Japanese earthquake and earthquakes occurred in China and its vicinity within 4 years (predominantly, M_s≥6.0). It is found that there are good correlations between great earthquakes in Japan and moderate-strong earthquakes in China and its vicinity. By studying the correlation characteristics, there are lag intervals, mostly from 6 months to 2 years but no more than 4 years, when earthquakes occurred in China after earthquakes in Japan. The "teleconnection prediction method" to predict the moderate-strong seismic risk regions in China and its vicinity is applied and positive results of 82% correctness (6 false predictions in 34 earthquake regions) are obtained. We try to use a "spider web" model of reverse reaction to explain the correlativity of earthquakes which we studied.
