Mw 7.3 Southeastern Missouri

updated 22 January 2023

report

On 23 January 1812 a major earthquake occurred in Southeastern Missouri. The seismic event occurred at 15:00 UTC and had an estimated moment magnitude (Mw) 7.3.

The estimated primary trigger of this seismic event is critical lunar geometry with Jupiter and Saturn due to Earth's position between the two Jovians, which were on opposite sides of the Solar System in 1811-1812.

On 17 January 1812 a Jupiter-Mercury-Saturn conjunction occurred due to the positions of Jupiter and Saturn on opposite sides of the Solar System. Major earthquakes already occurred in the region in December 1811, after critical lunar geometry with the two Jovians occurred. The same geometry occurred on 19 January and on 22 January 1812. A fourth major earthquake in the region occurred on 7 February 1812.
