从1988年到1998年10年间,我国发生7级以上的地震就有7次,表明我国进入一个新的地震活跃期。地震是一种灾难性自然现象,为什么不能像天气预报那样准确地预报地震呢?关键问题是地震发生在地下少则十几公里、多则数百公里,其形成的机理极为复杂,难以侦察到地下恶魔的行踪。地震科技工作者目前手中尚未拥有一张地震“云图”王牌,故预报地震就很棘手,很困惑,且预报
During the 10 years from 1988 to 1998, seven earthquakes of magnitude 7 or above occurred in our country, indicating that China has entered a new period of active earthquake. Earthquake is a catastrophic natural phenomenon, why can not predict the earthquakes accurately as weather forecasting? The key problem is that earthquakes occur in the ground less than ten kilometers, as many as hundreds of kilometers, the formation of the mechanism is extremely complex and difficult to detect The whereabouts of the underground devil. At present, earthquake science and technology workers have not yet possessed an earthquake “cloud map” trump card, so the earthquake prediction is tricky and confusing, and the forecast
