Mw 8.2 Off West Coast of Northern Sumatra

updated 28 January 2023

report

On 11 April 2012 a great earthquake occurred off the west coast of Northern Sumatra at a depth of 10 km. The seismic event occurred at 10:43:10 UTC and had an estimated moment magnitude (Mw) 8.2. It was the second great earthquake in two hours.

The estimated primary trigger of this seismic event is critical lunar geometry on 9 April 2012.

A convergence of critical planetary geometry (PGme, PGve) occurred on 4 April 2012 and was followed by a planetary conjunction Mercury-Sun-Jupiter on 5 April. Due to Earth's close proximity to the Mars-Neptune vector critical lunar geometry in the form of opposite right and semi-right angles occurred on 6 and 9 April with both outer planets, while lunar conjunctions with Saturn and Jupiter occurred on 7-8 April. The critical lunar geometry on 9 April coincided with critical planetary geometry (PGme).

The planetary and lunar geometry involving Mars and Neptune in April 2012 is comparable to the geometry in January-March 1957 that resulted in a mega-thrust earthquake in March.
