A major earthquake hit southern Mexico this morning near Oaxaca. This measured M7.4 and triggered a tsunami warning along regional Pacific coastlines. As of this post time, a small tsunami less than 1 meter (3.3 feet) was observed.

If you are keeping track, this is with 48 hours of the ring of fire solar eclipse and less than 3 days after the summer solstice.

Videos from the region have been uploaded. I’ve gathered a few here.  See the regional report and history from USGS below:

From The USGS

The June 23, 2020, M 7.4 earthquake near Oaxaca, Mexico occurred as the result of reverse faulting on or near the plate boundary between the Cocos and North American plates. Focal mechanism solutions for the event indicate rupture occurred on either a shallowly dipping thrust fault striking towards the west or on a steeply dipping reverse fault striking towards the ESE. The depth and focal mechanism solutions of the event are consistent with its occurrence on the subduction zone interface between these plates, approximately 100 km northeast of the Middle America Trench, where the Cocos plate begins its descent into the mantle beneath Mexico. In the region of this earthquake, the Cocos plate moves approximately northeastward at a rate of 60 mm/yr.
