我国是一个多地震的国家,据资料记载,自公元前1813年至公元1985年,共发生7级以上地震145次,其中8级地震19)次。这些地震给我国人民带来了巨大灾难,特别是1966年至1976年的10年间,在我国人口稠密的地区相继发生了9次7级以上地震,其造成的伤亡和损失更为严重。据统计,在9大地震中共死亡近30万人。因此,实现地震预报,减轻人民生命财产损失成了地震工作者的当务之急。 地震预报是以观测为基础的科学。短临预报是地震预报的主要目标。
Our country is a country with many earthquakes. According to the records, there were 145 earthquakes of magnitude 7 or above from 1813 to the year 1985, of which 8 were of magnitude 19). These earthquakes brought great disaster to our people. In particular, during the 10 years from 1966 to 1976, 9 earthquakes of magnitude 7 or above occurred in the densely populated areas of our country, causing even more serious injuries and losses. Statistics show that there were nearly 300,000 deaths in the 9 major earthquakes. Therefore, it is imperative for earthquake workers to realize earthquake prediction and reduce people’s loss of life and property. Earthquake prediction is observation-based science. Short-term prediction is the main target of earthquake prediction.
