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!

If you're going to worry about shit, you should probably try to understand it a little bit better than this.

Not really. It is true that geologists have identified some patterns in large quakes causing smaller quakes at significant distances.

A major quake that takes hundreds of years to build up stress in a fault, however, would almost certainly have to be just about ready to slip regardless for a smaller quake to trigger them. I can't tell you exactly what that means, but I would guess it would be a matter of causing a quake that was going to occur "soon" to instead occur maybe a few months, or perhaps a year or two earlier.

Unless geologists identify a pattern of seismicity along the Cascadia subduction zone that suggests to them a rupture is imminent, I'm sticking to my plan of general readiness to shelter in place (whether sheltering in place or evacuating is the best option depends where you live, and what the disaster is): Keep at least 3 days worth of food and water, and a way to stay safely warm if the power is out, etc. Visit ready.gov if you want more disaster prep advice.

We keep a well-stocked pantry, my camping gear serves for cooking when the power is out, and if we completely drained our water heater, and it didn't rain, I also have a camping water filter good enough to remove bacterial contaminants, or I can boil water to help tie me over for a couple weeks while waiting for relief supplies to reach the whole region.

Nah, there are slim chances that will affect anything here. And the Nisqually quake was a wild ride so bring it.
