祁连山-六盘山地震带中强地震活动特点及震前异常特征

FEATURES OF MODERATE-STRONG EARTHQUAKE ACTIVITY AND ANOMALOUS FEATURES BEFORE EARTHQUAKES IN QILIAN MT.-LIUPAN MT.EARTHQUAKE BELT

摘要:

将祁连山-六盘山地震带分为东、中、西三段,以分段的方式研究了该带中强地震的迁移特点,并对各段地震活动进行了统计研究,得到各段的迁移规律和各段中强地震震前异常特征.

Abstract:

In this paper, Qilian Mt.-Liupan Mt. earthquake belt is divided into three sections:the east, the middle and the west section.The migration features of moderate-strong earthquakes among sections are studied, and the statistical study on seismicities of every section is done also. So the migration regulations and the anomalous features before moderate-strong earthquakes in three sections of Qilian Mt.-Liupan Mt. earthquake belt are obtained.
