A series of earthquakes off the Oregon coast were recorded Saturday by the US Geologic Survey, with the strongest registering at 5.4 about 10 kilometers deep.




USGS


So far there have been eight quakes off the coast of Oregon today. This is not highly unusual but not normal either. I am always up for some good EQ doom porn. This zone is worth keeping an eye on. A big quake at this location could cause huge problems. Lets hope it doesn't happen anytime soon, but the odds are there will be a megaquake in this zone at some point.

This is from 2018, but still relevant.

The geologic record suggests that the fault has produced catastrophic quakes of magnitude 8.0 to 9.0, along with destructive tsunamis, at least every 500 years or so. The last major quake rumbled up the coast in 1700, with an estimated magnitude of 8.7 to 9.2.


The Next Cascadian Megaquake May Be Sooner Than You Think

A megaquake along the Cascadia subduction zone could cause massive damage to America's Pacific Northwest coast by triggering landslides and tsunamis. It would also cause a lot of damage elsewhere if a large tsunami is produced. Take a look at the video. It shows a simulation of the megaquake in 1700.

Isn't that near where the underwater volcano is? Could it just be reloading it's magma chamber?

Good point, there are a number of volcanoes in the area.

Cascade Volcanoes


Because the population of the Pacific Northwest is rapidly increasing, the Cascade volcanoes are some of the most dangerous, due to their eruptive history and potential for future eruptions, and because they are underlain by weak, hydrothermally altered volcanic rocks that are susceptible to failure. Consequently, Mount Rainier is one of the Decade Volcanoes identified by the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) as being worthy of particular study, due to the danger it poses to Seattle and Tacoma. Many large, long-runout landslides originating on Cascade volcanoes have engulfed valleys tens of kilometers from their sources, and some of the areas affected now support large populations.



The Axial Seamount is in the area.


Axial Seamount received significant scientific attention following the seismic detection of a submarine eruption at the volcano in January 1998, the first time a submarine eruption had been detected and followed in situ. Subsequent cruises and analysis showed that the volcano had generated lava flows up to 13 m (43 ft) thick, and the total eruptive volume was found to be 18,000–76,000 km3 (4,300–18,200 cu mi). Axial Seamount erupted again in April 2011, producing a mile-wide lava flow. There was another eruption in 2015.


And a few others.

I'm thinking that this will not be a good prognosis for some people living in that area, including some of Northern California.. I read some articles about quakes in that region years back and it could lead to a big quake in that area and lower down. It may not be an indicator of a large quake, but then again, any quake in that particular area could be a pre-quake of a much larger event.

I don't live there, so I did not study it extensively, I only read about five articles on it the last time the series of little quakes hit in that region. I am sure that they will warn the people if the risk goes up....
yeah right, they will not put their reputation in jeopardy by trying to predict something if they do not have positive proof.

Had one here in Nebraska at 4am today (Saturday).
