Two shallow M5.9 earthquakes hit off the coast of southern Oregon, U.S. at 07:52 and 08:17 UTC on June 4, 2021, at a depth of 16.6 km (10.3 miles) and 14.5 km (9 miles), respectively. They were located around 12 km (7.4 miles) from each other and followed by 5 moderately strong aftershocks over the next 15 hours. 13 M6+ earthquakes have occurred within 200 km (124 miles) in the last 50 years. The largest of which was a M7.2 earthquake on June 15, 2005.
These earthquakes occurred as the result of shallow strike-slip faulting within a deformed section of the southernmost oceanic crust of the Juan de Fuca plate, commonly called the Gorda plate, west of the Cascadia subduction zone, the USGS said.
Focal mechanism solutions indicate that rupture occurred on either a left-lateral northeast-southwest-striking fault or on a right-lateral southeast-northwest-striking fault. Near the location of the earthquakes, the Juan de Fuca plate moves to the northeast relative to the North America plate at a velocity of about 30 mm (1.18 inches) per year.
"Earthquakes are common in the Gorda plate, which is subjected to internal deformation originating from interactions with both the Pacific plate to the south and the North American plate to the east," USGS said.

I feel the earth move under my feet.
Didn’t feel a thing.
About a half hour ago we had about a 5.2 shaker located in Calipatria near El Centro, east of San Diego, near where the San Andreas fault runs into the Gulf of Baja. Felt a good jolt where I live in Alpine, 30 miles east of San Diego.
Focal mechanism solutions?
Too funny!
Thanks
I feel the sky come tumblin’ down.
Just now another 5.3 off Calipatria CA
Looking at the USGS site, it’s been SUPER active around Calipatria all day, with minor shallow quakes every few MINUTES!
Is that the cluster near the Salton Sea?
Yes. It looks to be quite active indeed!
Saint Andreas, hear our prayer!
Meanwhile remember that man is in charge of the earth.
There has been more than normal activity in this area for a couple years.
Hmmm

A good tsunami might relieve some of their severe drought conditions.
