地震预报与活断层分段

文章回顾分析了地震预报的经验与问题,对地震短期预报需进行新的探索与研讨,才能更快地前进。文章重点论述了地震预报和地震危险性评估方面有关的断层分段性问题。如何在众多的活断层上确定近期可能发生强震的地段,是地震预报中突出的重要问题之一。有关活断层分段性问题是近年来十分引人注目的课题。段是断层的破裂单元,断层的分段就是对断层进行独立的破裂单元的划分。断层分段有4种,当前讨论的主要是活断层破裂分段。

EARTHQUAKE PREDICTION AND ACTIVE FAULT SEGMENTATION

Author reviews and analyzes the experience and question of earthquake prediction, and recognizes that the short-term earthquake prediction is only searched and discussed further, it will rapidly achieve progressing.This paper mainly discusses the fault segmentation associated with earthquake prediction and risk evaluation. It is one of the most important problem how to determine that strong earthquake will probably occur in a certain segment of many recent active faults. The problem of active fault segmentation is very noticeable task in recent years. The segment of a fault are referred to as the rupture element of the fault. It is the fault segmentation that the independent rupture element of fault is divided. There are four methods in the fault segmentation. What is discussed recently is mainly the rupture segmentation of the active faults.
