Seismologists say Friday's earthquake may not have been strong enough to release all that built-up tectonic pressure. There have been predictions that an 8 magnitude earthquake could see horizontal surface displacement of more than 6 metres along the mountains.

"The 2015 was not a mega earthquake, that one is still coming," warned Surya Narayan Shrestha of the National Society for Earthquake Technology (NSET) in an interview with Nepali Times on Nepal’s Earthquake Safety Day on 15 January this year.

Written records in monasteries in western Tibet chronicle a big earthquake at 6AM on 1 June 1505, and that could have been the last big one that shook western Nepal. Estimated at 8.9, there are also historical records in Moghul India of destruction in Agra and other cities at the time.
