List of aftershocks of the April 2015 Nepal earthquake

Add article description


The following is a list of aftershocks that occurred after the earthquake in Nepal on 25 April 2015. There was some seismic activity in the Jumla district before the main shock.[1][2] However, they are not foreshocks to the main shock. As of 7 June 2015, over 304 aftershocks have occurred.[3] The large number of aftershocks after the earthquake is considered normal by seismologists.

According to seismologist Roger Musson, the standard pattern for aftershocks is that the biggest aftershock will be one day after, and one magnitude less. Thus, the 6.7 magnitude aftershock on 26 April 2015 following the 7.9 magnitude main shock would fit this pattern. It is highly unlikely that the earthquake was a foreshock preceding an even larger earthquake. Therefore, an earthquake larger than 7.9 in the near future after 25 April 2015 is not expected.[4]
