摘要/Abstract

摘要： 地震现场的构造磁学观测研究表明, 在地震之前与地震之时存在明显的磁场异常变化。震磁前兆基本上是近场效应 ,其震中距为几公里至几十公里, 其变化幅度为几 nT ,前兆时间为几天至一年多。火山构造磁学研究的新进展, 进一步表明了火山磁效应与地震、形变、破裂、喷发等火山活动状态密切相关 ,为监测与预测火山喷发灾害提供了重要的基础与方法。根据构造磁学的物理基础 ,积极开展了地震预测研究, 显示了构造磁学在地震预测研究中的良好前景 ,但目前仍处于积累资料与试验阶段 ,今后应当进一步观测研究。

Abstract: The tectonomagnetism investigations in the earthquake region show that obvio us anomalous changes in the magnetic field exist pre- and co-earthquakes. The seismomagnetic precursors basically are near-field effects; the epicentral distances are several to tens km; the change amplitudes are several nT; the time precursors last is several days to more than one year.New progresses of the research on volcano- tectonomagnetism further show that the volcano-magnetic effects are closely related to the volcano-activity states, such as volcano -earthquake, deformation, fracture and eruption; it provides important basis and method for monitoring and predicting volcano -eruption hazards. According to the physical basis of tectonomagnetism, earthquake prediction is actively carried out, showing a perspective earthquake prediction research by mea ns of tectonomagnetism. Ho w ever, it is still situated at the period of data accumulation and the trial stage, and further observation and research should be made in the future.

Key words: Tectonomagnetism, Seismomagnetic effect, Volcano-magnetic effect, Earthquake prediction
