QUAKE SWARM----Interesting earthquake swarm in northwestern Nevada

[nikto]

The quake swarm is occurring in a sparsley-populated area near the California border where scientists have located
several ancient calderas which are thought to be an extension of the Yellowstone eruption sequence.

Could the quakes be volcanic-related?

1. I always thought it would be cool if a new volcano grew somewhere like Paricutin did in

Mexico in 1943. As long as it is a small volcano though

2. Latest report is a 4.7 at 5km which could indicate a volcanic disturbance. I agree,

a small one, we hope.

7. Dunno, too widely scattered for a typical eruption

but it was my first question when I noticed the swarm of shallow quakes, myself.

It looks like there is movement over a wide area. It would be nice to know if the area is rising or sinking.

10. I had the same thought

I've traveled around a lot of those remote CA/Nev desert areas,
and those places have lots & lots of cinder cones, probably many thousands of years old,
many only a 100 or so feet high (no doubt eroded).
I've seen cows grazing on them in places.

It seems the eruption area/magma field must have shifted away from those areas so those cinder cone vents stayed small.

Parícutin, only 70 years old, has since grown and is bigger at 600-700 feet.

In human time, it's been a while since a CA/Nev eruption (except for Lassen, circa 1915).

We normally think of eruptions as happening at big volcanoes.
But I'm sure those cinder cones go off pretty hard when they are created, even if geologically,
they turn out to be "1-shot deals".
Could be pretty spectacular.


Maybe a new cinder cone is on the way?

3. Wow. I remember in grade school my teacher telling us volcanoes can erput anywhere...

don't know how true that is, but this is probably what she was referring to.
Thanks for posting!

4. Quite a few earthquakes yesterday per USGS map

5. 17 of magnitude 2.5 or greater in the last 24 hours

Worth keeping an eye on.

6. Did you notice the ones in OK? I didn't know that was earthquake country. Fracking? nt

[Warpy]

8. OK earthquakes, which have been going on for several years,

are almost certainly the result of fracking.

[nikto]

11. Fracking is the cause in most cases, for sure

A shallow epicenter is one clue (often under 3Km, although a few deeper quakes can result as well).

9. It's all cracking open!
