- Abstract:
- Through abundant data of historical and modern strong earthquakes in Yunnan region,we analyze the time interval of strong earthquakes and established a time-prediction equation,tf=a+bβα,for strong earthquakes.According to the data of M≥6 earthquakes in Yunnan region,we fit the time-prediction equation in different periods and in different parts of Yunnan.The equation is effective in simulating the temporal characteristics of strong earthquakes from 1500 to 2008.The formula T(M)=D(T)/N(M) is also effective in estimating the recurrence period of strong earthquakes,based on time interval data of M≥6.5 earthquakes about 500 years in Yunnan region.The advantages of time-prediction equation for strong earthquakes in the paper are of high precision,small error and full use of abundant history data.The statistical analysis shows that strong-earthquake activities in Yunnan region will probably come to a dangerous period in the future.
