地震分布规律研究(2)

Abstract

本文考察了近17年世界和中国大地震的分布规律。世界大地震多数发生在环太平洋地震带(环太平洋周边的斜坡上)，中国大地震多数发生在喜马拉雅山脉及青藏高原周边斜坡地区。从近千年中国发生的产生较大伤亡的大地震来看，南从云南丽江附近，北到辽宁海城附近，形成一条近乎直线的地震带，在这附近发生大地震的几率较其他地方大得多。 This paper investigates the distribution of major earthquakes in the world and China in the past 17 years. Most of the world’s major earthquakes occurred in the Pacific Rim seismic belt, and most of the China’s earthquakes occurred in the Himalayas and the slopes around the Qinghai-Tibet Plateau. According to the large earthquakes happened in China in the past thousand years, a linear seismic zone was formed from Lijiang in Yunnan to Haicheng in Liaoning. The probability of a major earthquake in the vicinity was much higher than other places.
