M 6.7 earthquake Central Mid-Atlantic Ridge

last updated 24 May 2021

A strong earthquake occurred on the Central Mid-Atlantic Ridge on 18 September 2020 at 21:43 UTC. The estimated moment magnitude is 6.7.

No critical planetary geometry occurred prior to this earthquake. Lunar geometry prior to the earthquake was similar to that of 20 August, before to the M 6.9 earthquake deep under the Banda Sea, i.e. 135° with Mars and Saturn.

Update 28 May 2021: A WPG peak formed on the 14th followed by a higher lunar peak (geometry index 10) on the 16th and 17th, partly due to the geometry involving Mars and Saturn.
