摘要

本文分析了1900年以来祁连山地震带发生7.0级以上强震后，中部地区5.0级以上地震的发生情况。研究发现，该地区距震中100~220 km范围内的5.0级以上地震在7.0级以上地震发生1~6年后明显增强，显示出地震活动性增强作用。23~56年7.0级以上强震后5.0级以上地震的地震活动性

Attenuation Characteristics of Earthquakes with M ≥ 7.0 in Qilian Mountain Seismic Zone Since 1900

In this paper, the occurrence of earthquakes with M ≥ 5.0 in the central area after strong earth-quakes with M ≥ 7.0 in the Qilian Mountain seismic zone since 1900 is analyzed. It is found that earthquakes with M ≥ 5.0 within 100~220 km of the epicenter are obviously enhanced 1~6 years after earthquakes with M ≥ 7.0 in this region, which shows the seismicity enhancement effect. The seismicity of earthquakes with M ≥ 5.0 after 23~56 years strong earthquakes with M ≥ 7.0 de-任雪梅，李文君

期刊介绍： Advances in Geosciences (ADGEO) is an international, interdisciplinary journal for fast publication of collections of short, but self-contained communications in the Earth, planetary and solar system sciences, published in separate volumes online with the option of a publication on paper (print-on-demand). The collections may include papers presented at scientific meetings (proceedings) or articles on a well defined topic compiled by individual editors or organizations (special publications). The evaluation of the manuscript is organized by Guest-Editors, i.e. either by the conveners of a session of a conference or by the organizers of a meeting or workshop or by editors appointed otherwise, and their chosen referees.
