We quoted total 67 seismic events of Ms=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 Ms≥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, Ms≥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. ©, 2014, China University of Geosciences. All right reserved. Source

The relationship between solar activity and earthquake in the world was studied by applying a dimensionless function of seismic energy √G to investigate the energy release time series of global large earthquakes (M≥7.0) occurred during the year of 1681-2011. From the study, we find that the distribution and activity of global large earthquake in 4 phases of solar cycle varied with magnitude. We suggest that it can be explained by a model of load-unload response of the earth crustal movement to solar storm. The findings of spatial and temporal distribution characteristics of 10 M≥9.0 super earthquakes in past years of 331 in the world and absence of super earthquake in solar maximum. The results are helpful to predict occurrence of future global large earthquake as reference. ©, 2014, China University of Geosciences. All right reserved. Source
