Mw 6.6 Java Sea
updated 8 August 2021

On 19 October 2016 a strong earthquake occurred in the Java Sea at a depth of 645 km(!). The seismic event occurred at 00:26:02 UTC and had an estimated moment magnitude (Mw) 6.6.

Two planetary alignments on the 15th and 17th preceded the earthquake, while a third occurred at the time of the earthquake when lunar geometry reached index 13. Particularly critical was the Full Moon on the 16th in combination with a Moon-Uranus conjunction. A first strong earthquake on the 17th (Mw 6.8) occurred as a result. Note that no similar strong or larger seismic activity occurred in the three weeks before or after these two strong earthquakes.
