Definition of 地震前兆 in the Chinese dictionary
Seismic activity, crustal deformation, groundwater level, geoelectric force, geomagnetism, and the response of animals and plants occurred abnormally before earthquakes occurred. However, the "precursors" that are bound to appear before the earthquake have not yet been confirmed. Therefore, a comprehensive analysis of earthquake precursors is needed to make an accurate earthquake prediction. 地震前兆 震前发生的与地震有内在联系的地震活动性、地壳形变、地下水位、地电、地磁和动植物反应等异常变化。但因地震前必然要出现的“前兆”尚未确证,故需对地震前兆作综合分析,以便准确作出地震预报。
