The long-term earthquake prediction And short-term earthquake prediction, the long-term earthquake prediction can be achieved, mainly based on the fault of seismologists and geological structure of the study (Figure 4). The long-term earthquake prediction than the prediction of climate (long-term weather forecast) better, because the earthquake occurred in a certain place with a big geological structure, an 8 earthquake will not happen in the Ordos platform such as the stability of the geological unit . The human fault, and other geological studies have been hundreds of years of history and knowledge to provide the long-term earthquake prediction on the basis of the information. As for the prediction of climate, the wet weather next year, where the flood occurred, it is difficult to judge.这个是关于地震的长期预告的 我还有图 可不能发图 这俩个网站的不错 虽然是中文的 找个在线翻译过来就行了
