Mw 7.8 Nepal
updated 28 May 2021 UTC

On 25 April 2015 a major earthquake occurred in Nepal. The seismic event occurred at 06:11:26 UTC and had an estimated moment magnitude (Mw) 7.8. It was followed by strong aftershocks, a Mw 6.7 at 06:45:22 UTC and also the following day at 07:09:10 UTC. A major aftershock measuring Mw 7.3 occurred on 12 May.

This seismic increase was anticipated and it was the first successful forecast by Ditrianum posted on 20 April 2015 because of the critical alignment of Earth with Mercury and Mars that could potentially result in larger seismic activity from the 22nd to the 27th.

More recent analysis confirms that the earthquake was also preceded by three WPG peaks from the 20th to the 24th, which was a decisive contributor.
