Mw 7.8 South of Puerto Chacabuco, Aisen, Chile
updated 27 August 2021

On 6 June 1960 a major earthquake occurred South of Puerto Chacabuco, Aisen, Chile at a depth of 15 km. The seismic event occurred at 05:55:48 UTC and had an estimated moment magnitude (Mw) 7.8. While this earthquake could be considered an aftershock or after-effect of the intense seismic activity two weeks earlier, the planetary geometry explained below suggests that the stress release was specifically initiated.

Three planetary alignments from 3 to 5 June preceded the earthquake, all of which involved Mercury. Critical was the Mercury-Earth-Jupiter alignment on the 3rd and especially the Venus-Mercury-Neptune alignment on the 5th, about 24 hours before the earthquake occurred. Following this planetary geometry, a lunar peak occurred on the 5th peaking 8, but it involved an alignment (opposition) with Mars, a synchronicity seen repeatedly before large earthquakes, such as two weeks earlier (conjunction), and also with the second largest earthquake on record in 1964.
