Abstract

This paper briefly introduces the parameters of the M 8.1 earthquake on April 25, 2015, which is a low angle thrust fault movement in the middle of the Himalaya orogenic belt. The characteristics is that the source is very shallow, the intensity of the earthquake reaches to Ⅺ degree and the earthquake damage is severe. The rupture zone have a strike of the North West-South East, crossing the Nepalese capital Kathmandu, where the construction suffered serious damage. The earthquake was the largest earthquake in Nepal since 1934, which marking the end of the period of peace in Himalaya since 1950. Since entering the new active period in 2005, the great earthquake occurred in Nepal has reached the climax of the event in 2015, which is expected to last ten to several decades. According to the analysis of data of historical earthquakes, it may have a migration along the Himalayan zone in the future, and there will be larger earthquake in the eastern part of the Himalayan belt, so as to reach the top of earthquake tide and then have a end. There may be serious damage to the border of India, Bhutan and east-south region of Tibet. It is also possible to move northwardly along with the Himalaya belt in the vertical direction (i.e. horizontal migration), causing destructive earthquakes in Tibet, Qinghai in a few years. It needs to do a good job in monitoring, forecasting, and disaster prevention.
- earthquake climax,
- earthquake migration,
- seismic trend
