Mw 6.8 Washington

updated 15 December 2022

report

On 15 December 1872 a strong earthquake occurred in Washington. The seismic event occurred at 05:40:30 UTC and had an estimated moment magnitude (Mw) 6.8.

The estimated primary trigger of this seismic event is a convergence of a planetary conjunction and right angle plus a lunar conjunction on 10 December, followed by a lunar conjunction with the Sun (Full Moon) early on 15 December 1872.

On 10 December 1872 a critical planetary conjunction Venus-Mercury-Jupiter converged with a critical planetary right angle of Venus with Earth and Neptune, and a lunar conjunction, also with Neptune. The next lunar peak occurred on 13 December, two days before the earthquake.
