尽管短临地震预测非常重要,而且已经经过多年的研究,但仍然不能说是成功的。近期有许多关于地震的地磁前兆的文献报道。其中,ULF电磁现象和电离层扰动现象被认为是观测地壳活动的最有前景的方法之一。在台湾的东海岸,中/大地震出现的频率非常高,几乎是日本的10倍。因此,在台湾安装了地磁仪和电极来测量ULF地磁场和地电势差,以评价以前获得的研究结果,并试图阐明与大地震相关的ULF电磁现象的物理机制。同样,为了阐明大地震之前出现的电离层扰动现象的可能机制,还开始了监测大气电场的变化。本文中将会陈述台湾的地震电磁现象观测的策略及最初始的成果。
Although short-term and short-term earthquake prediction is very important and has been studied for many years, it still can not be said to be successful. There have been many recent reports of geomagnetic precursors for earthquakes. Among them, ULF electromagnetic phenomena and ionospheric disturbances are considered as one of the most promising methods for observing the activity of the earth’s crust. On the east coast of Taiwan, the medium / large earthquakes have seen a high frequency of almost 10 times that of Japan. Therefore, geomagnetic sensors and electrodes were installed in Taiwan to measure the ULF geomagnetic field and ground potential differences to evaluate previously obtained findings and to attempt to elucidate the physical mechanism of ULF electromagnetic phenomena associated with large earthquakes. Similarly, in order to clarify possible mechanisms of ionospheric disturbances that preceded the major earthquakes, the monitoring of changes in the electric field in the atmosphere was also started. This article will present Taiwan’s strategy for the observation of seismic electromagnetic phenomena and the initial results.
