Another Cascadia Earthquake? ...

[HB of CJ]

On 16 Nov., 2020. A 3.7 10 km deep off the Southern Oregon Coast. Might be off the Northern CA coast also. Not sure here.

That is all.

Thursday, 26 November, 2020. A 2.9 or soosss about 15 minutes, (tsunami speed!) West of Crescent City CA. About 10.0 km deep again.

That is all.

A couple just about one hour ago about 150 miles West of Petrolia CA. Shallow. One about 4.1, the other about 2.7 or so.

That is all except Chuck Yeager died. ;(

A 3.1 today about 10 km deep about 185 km West of Bandon Oregon. On the fault? Seems so.

That is all.

 

[HB of CJ]

A 3.5 today, 15 December, 2020 about 185 km West of Bandon Oregon. 10 km deep. On the fault? Seems so. I am beginning to get a bad feeling about this.

That is all.

Faults typically do stay active. A little activity all the time is usually better than nothing for a long time.

In reality "the big one" could happen in the next ten seconds, or it could happen 500 years from now. In geologic time both of them are barely a blink.

That is all.

Keep in mind that is not a vertical fault, those quakes are on or near the 'trailing' edge of the plate boundry. The 'leading' edge, or bottom if you want to think of that way is a few hundred kilometers East.

You can bring up the tremor map like DutchSinse does on his videos. It the show the tremor map of the Juan De Fuca Plate.

The magnitude is less than a 2.0 but you see the movement from Vancouver Island, Washington, Oregon, and Northern California. You can select by date.

Today, a 4.3 or so about 10 km deep about 110 km W. of Port Mcneill BC. Northern end?

That is all.

Two more today; a dinky one and a pretty good one W. of Bandon Oregon. 10 km deep. Did anybody along the central Oregon coast feel these?

That is all.

Hike into Cape Lookout and view the splash line caused by the Cascadia event...clear to see, full on scrub line 90' up the face of the vertical rocky cliff above the beach. Mind you, that's not caused by a wave, it's caused by the entire ocean being lifted up and surging east....happens again, say goodby to every coastal neighborhood not on a high hill for miles inland.

A 3.9 today off the Oregon Coast. About 10 km deep.

That is all.

A swarm of approximately 100 went off on the south flank of Mt. Hood yesterday. Largest was only 2.7, and all were deep. The graphic looked like someone shot a map of the Southwest side of Hood with a shotgun...

I actually vetoed my daughters ski trip today because of that. Mt Hood is expected to blow laterally. Last eruption was in late 1700s. It’s coming due, and I didn’t like the full choke pattern.

 

[GWS]

If Mt. Hood blow out on the south side, what's in the way?

 

[JeremyK]

We’re really worried about a theoretical earthquake at this point?

Worried, not so much. Interested, yes, most definitely.
Local emergency management is very concerned about a Cascadia subduction zone earthquake that is supposedly imminent and earthquakes, especially swarms of earthquakes may be indicators of something greater.
If seismic activity bores you, perhaps you should consider following another thread.

A 4.6 about 2.2 km deep, (quite shallow) about 234 km West of Ferndale CA. May be south of Cascadia. Dunno fur sures.

That is all.
