甘肃省地震烈度衰减关系研究

Study on the Attenuation Relationship of Seismic Intensity in Gansu Province

摘要:

选取了甘肃省内1950-2004年间主震震级M≥5.0、震中烈度I0≥V的地震20次,回归分析得出了适合本地区特点的地震烈度衰减关系,并与目前甘肃省广泛使用的西部地区地震烈度衰减关系进行了比较和分析。

Abstract:

For the purpose of acquiring the intensity attenuation relationship fitted the Gansu province,in this paper,20 earthquakes occurred from 1950-2004 in Gansu province are selected,the host shake＇s magnitude of which were all greater than or equal to 5.0 and the epicenter intensity were greater than or equal to V.On the basis of above materials,the attenuation relationship of this area was achieved and some analysis and comparison were made between the attenuation relationship of Gansu area and the existing results of western of China.
