【摘要】 通过对现今和历史地震资料的分析研究可以看出:甘肃和山西两地地震存在着较好的相关性。这种相关性的内在联系可能依赖于它们共同所处的地质构造背景—祁连山、吕梁山、贺兰山的"山"字型活动构造体系,可能是欧亚板块东南部在印度洋板块向北俯冲作用力和太平洋板块向西挤压作用力的共同影响下,该活动构造体系产生的一种应激响应。更多还原

【Abstract】 The recent and historical seismic data are analyzed,and the results show that the earthquakes in Gansu and Shanxi provinces have better correlation.The inner connection of the correlation may be relied on their same geological tectonic background — Qilianshan-Lüliangshan-Helanshan mountains active tectonic system,perhaps southeast area of Europe and Asia block may be effected by Indian Ocean block toward north dive and the Pacific Ocean block to west extruding influence,so that this active tectonic system are responded.更多还原
