Mw 7.7 Potosi, Bolivia

updated 26 January 2023

report

On 29 November 1957 a major earthquake occurred in Potosi, Bolivia at a depth of 232 km. The seismic event occurred at 22:19:50 UTC and had an estimated moment magnitude (Mw) 7.7.

The estimated primary trigger of this seismic event is a convergence of critical planetary and lunar geometry from 25 to 28 November 1957.

From 21 to 30 November 1957 five critical planetary conjunctions occurred involving Mercury and Venus. Following the planetary conjunctions that converged with lunar conjunctions involving the Sun (New Moon) and Saturn on 21-22 November, a clustering of strong earthquakes occurred with the next lunar peaks on 25-26 November. The planetary conjunction Mercury-Sun-Uranus later on 26 November was followed the next morning by a lunar peak, partially due to a lunar conjunction with Uranus. Following the Venus-Sun-Mars conjunction on 28 November, the major earthquake in Bolivia occurred with the lunar peaks on 29-30 November. The planetary conjunction on 28 November was also the first in a series that formed a near quadruple conjunction on 1-2 December that resulted in a great earthquake in Mongolia on 4 December.
