祁连山中东段三维构造物理模型及其在地震预报中的应用

THREE-DIMENSIONAL TECTONOPHYSICS MODEL FOR THE MIDDLE-EASTERN QILIAN MOUNTAINS AND ITS APPLICATION IN EARTHQUAKE PREDICTION

摘要:

利用近年来在祁连山中东段地区取得的丰富、完整、系统、可靠的地表活动构造定量化数据和测震学资料建立了本区全新世活动构造的三维构造物理模型,定性或半定量地描述了该区活动地块的运动状态,解释了不同活动块体的运动性质及块体之间的运动转换关系,归纳总结了不同块体内前兆异常及地震活动性特点.

Abstract:

The three dimensional tectonophysics model of Holocene active faults is set up by using plentiful,reliable and quantitative data about surface active structures and seismometric data obtained from Qilian Mountains area.The movement features of active blocks in the area are described qualitatively or semi quantitatively.The transformation relation of movements among different blocks is explained.The characters of precursory anomalies and seismicities within different blocks are summed up.
