摘要/Abstract

摘要： 应力触发和应力影概念及其在地震预报中的应用,是学术界关注的热点,尚有一系列需要研究的问题。例如初始应力场的确定,合理流变模型的选取和计算,孔隙压力的变化和影响,断层强度随时间的变化等。特别在估计应力场变化时,人们现今只注意到大地震对应力场造成的变化。一些新的观测事实表明,大量的小地震效应,慢地震的效应和无震滑动的效应,也不容忽视。定量考虑它们的效应,是今后应力触发和应力影研究中应该注意的课题。

Abstract: It is a frontier of contemporary research to apply the concepts of stress triggers and stress shadows to earthquake prediction, there are, however, a number of questions deserved in depth study. Among them are determination of initial stress field, choice of reasonable rheological models and their computation, variations of pore pressure and its effects, variation of fault strength with time. Particularly, in the present calculation of variations of stress field produced by fault dislocation, only the effects of large earthquakes have been included, but latest observations indicate that effects of large amount of small earthquakes, slow and quiet earthquakes, and aseismic slip are not negligible. Quantitative study of their effects is a promising direction in the research on stress triggers and stress shadows.

Key words: Stress triggers, Stress shadows, Earthquake prediction
