摘要
应用多重贝努利独立试验模型,研究2006~2020年问大陆发生7级以上大地震的频次及其概率,以及最大震级的预测问题。研究结果表明,2006~2020年问大陆发生7.0~7.9级和7.5~7.9级大地震1次以上的概率为1.00,发生8级大地震1次以上的概率为0.67,或者说其间肯定会发生7级大地震,而发生10次7.0~7.9级和1次7.5~7.9级大地震的可能性最大。若按超过概率水平0.10而论,发生7.0~7.9级地震最少发生8次,最多发生12次;发生7.5~7.9级地震为l~4次,发生1~2次8.0~8.9级大地震可能性最大。2020年前中国大陆发生最大地震的震级可能为7.5~7.9级。不排除发生8级地震的可能。
A study on prediction of number and maximum magnitude of great earthquakes (Ms≥7. 0) before 2020 in Chinars continent has been down by using n-multi Bernoulli model of independence test. The results show that the occurrence probability of earthquakes with Ms=7.0-7. 9 and Ms=7. 5-7. 9 are 1. 0; the occurrence probability of earthquakes with Ms≥8.0 is 0.67 before 2020 in China's continent. According to the preceding probability level of 0.10, numbers of earthquakes with Ms = 7.0 - 7.9, Ms = 7.5-7.9 and Ms≥8.0 would range from 8 to 12, 1 to 4 and 1 to 2, respectively. Therefore, the maximum magnitude of great earthquakes would be 7.5 - 7.9, and it doesn't exclude the possibility of earthquake occurrence with Ms≥8.0 before 2020 in China's continent.
