摘要

本文对中国东部中强以上地震与日本海域强震的相关性进行了专门研究。结果表明，中国华东沿海地区中强震与日本板缘强震（Ｍｓ≥７．０）有很好的相关性，其滞后时间多在一年以内，而中国大华北（包括东北）的中强以上地震与日本海强震（ＭＳ≥６．０）有很好的相关性，其滞后时间多在一年半之内。本文根据相关性还概括了相关模式。这说明中国东部中强以上地震主要受相邻的太平洋板块俯冲运动的控制，因此本项目的研究结果可直接用于中国东部地区的中短期地震预报。
In this paper, a special study on correlativity of the strong and moderate earthquakes occurring in the east part of China and the strong earthquakes occurring in Japan marine regions was made. The results obtained show that the strong and moderate earthquakes (all events of Ms≥5.0 and some ones of Ms=4.8,4.9)occuring in East China land and sea regions have good correlativity with the strong earthquakes (Ms≥7.0) occurring in Japan margin region of pacific Plate, and the latent time is mostly in a period of 1 year,secondly, the strong and moderate earthquakes (all events of Ms≥6.0 and some ones ofMs=5.4-5.9)occurring in the Great North China (included the Northeast China) region has good correlativity with the strong earthquakes (Ms≥6.0)in Japan sea region, and the latent time is mostly in a period of one and half year; Four kinds of correlativity models are summarized for the both cases. The above-mentioned results indicated that the strong and moderate earthquakes in East China are mainly caused and controlled by the subducting movement of Pacific Plate. Moreover, the results obtained may be directly applied to the medium and short-term earthquake predictions for East China.
