震磁效应研究及进展

Study and development of seismomagnetic effects

系统地介绍了目前人们对于压磁效应、感应磁效应、流变磁效应、电动磁效应、热磁效应及岩石破裂过程中的电磁效应机理的认识、研究进展以及利用震磁效应激发的地磁异常从地磁场的长期和短期变化中提取地震前兆的方法。在此基础上,提出了对震磁效应进一步研究的建议,强调应从加强地磁台网观测、改进震磁效应的实验及引入提取震磁异常新的方法3方面加强震磁效应的研究,更好地发挥地磁观测在地震监测预报中的作用。

We have systematically introduced study and development about the knowledge of mechanism of ”piezomagnetic effect”,”induced magnetic effect”,”rheological magnetic effect”, ”electrokinetic magnetic effect”,”thermomagnetic effect”,”electromagnetic effect during the fracture of rocks ”,and the various methods for extracting earthquake precursorfrom the secular and short term variations of geomagnetic field.This paper has put forward proposal for further study of seismomagnetic effects which is including strengthening geomagnetic observation,improving the seismomagnetic experiments and introducing advanced methods into the seismomagnetic anomalies extracting.We hope that the geomagnetic observation can play a important role in earthquake monitoring and predicting.
