云南7级大震前的中强地震密集现象研究
|
摘要
经研究发现20世纪云南7级大震前有中强地震密集的现象.根据中强地震的密集特征可对7级大震时间作出较好预报;再结合静中动地震的研究,可对7级大震地点作出较好预报.最后对二者的联系机理进行了讨论.
It is found that the phenomenon of concentration of medium-strong earthquakes before M≥(7.0) exists in 20th century in Yunan province.A flexible time prediction of main earthquakes can be made on the basis of the features of concentration of medium-strong earthquakes,and the epicenter of potential main earthquake can also be predicted through the study combining with "the earthquake in quiescence".At the end,the mechanism of relation between the foreshocks and main shock is discussed.
