旱震关系与大地震中期预报 总被引：4，自引：0，他引：4
本文论述了作者在研究孕震过程中的气象效应问题时发现:6级以上大地震的震中区,震前一至三年半时间内往往是旱区.旱区面积随震级大小而增减.在旱后第三年发震时,震级要比旱后第一年内发震增大半级.据此提出运用旱震关系进行大地震中期预报的方法原则。 相似文献

In order to approach the medium-range prediction of great earthquakes with Ms≥6, the author investigated the relation between drought and earthquakes and believed that the drought-earthquake relation is an effective method for the medinm-range prediction of great earthquakes.When the author studied the meteorological effects on the earthquake preparation, he found that the epiecntral regions of great earthquakes with M≥6 are usually dry for one to three and a half years before earthquakes. The draught area changes with the earthquake magnitude proportionally. If an earthquake occurs in the 3rd year of drought, its magnitude is 0.5 higher than that in the 1st year of the drought.According to the above-mentioned facts, the author puts forth the medium-range prediction method and principle of great earthquakes by the drought-earthquake relation: (ⅰ) the magnitude is defined in accordnce with the area of the drought regious; (ⅱ) the possible risk area is defined on the basis of the location of the droug 相似文献
