Nah. Different fault lines.

Very excited to go spend Christmas 40m from the epicenter of the Cali one though 🫠

From the USGS comments, it sounds like it is actually related, but still not a specific concern:

https://en.wikipedia.org/wiki/Gorda_Plate

> ...in the vicinity of the Mendocino triple junction – the region where the Pacific, North America, and Juan de Fuca/Gorda plates meet. Focal mechanism solutions indicate that rupture occurred as a result of strike-slip faulting on a steeply dipping fault striking either southeast or southwest. The location, depth and faulting mechanism indicate that this event likely occurred within the subducting Gorda Plate.

Since the Gorda plate is described by the USGS as connected to the Juan de Fuca plate, and the eastern boundary of the Gorda Plate is considered part of the Cascadia subduction zone, this does seem pretty relevant.

However, they also note that this level of activity is pretty typical in this area. They mention a M6.2 earthquake only 20 km away last year, and 40 quakes over M6 in the general vicinity over the last century, including 6 over M7.

Enjoy. I graduated from HSU, oh sorry Cal Poly Humboldt. (Stupid name)

Save the Gorda Plate!
