Even though I do not write a lot on this thread because Apex is doing a great job with it.
I have to admit that I keep a close eye on quakes by means of many websites of Earthquakes Centers Worldwide.

Did you noticed that there seems to be an increase of seismic activity?

I mean in California & Nevada, but specially California (southern and northern, as well as Baja California, México)...

Do you mean like how there are currently nearly 800 quakes on the America maps? I thought that was quite a lot too.

Yes, Apex, that is exactly what I mean. It is amazing the high number of quakes

Up to now, today:

4.8 Off the Coast of Oregon
3.2 Nevada
3.2 Southern California
2.6 Central California
2.5 Central California

I do not like to say this, but is it possible that something big is going to happen?
Aren´t they more frequent and extended?
I mean, what about Nevada, Oregon, Ohio... ? They are also active.

Could all this be caused or affect the Yellowstone area?
And what could happen if there is a strong quake, say for instance in California?
Of course, there is no historical data and experience to know if it could trigger the Yellowstone Supervolcano, but I think that many parts are connected underground and therefore, can possibly react to such an event.

We have to keep an eye on this.
Don´t you think so?

Well, I vaguely remember seeing a large number of quakes (about 700 I think) sometime in 2005 on those maps, and nothing happened then, but It's impossible to tell what might be about to happen. I think it is possible that something could happen elsewhere such as Yellowstone, Although the quakes around the Juan de Fuca plate are quite worrying too, Rainier and St Helens are up there, and something in that area could be really bad. Having Said that, the Long Valley Caldera hasn't erupted in a large way for something like 780,000 years I believe, and that is in California.

Of course, the San Andreas is a transverse fault, so it may not affect the volcanoes at all, but the long distance energy could potentially I suppose. The difficult thing is, I think, knowing what other consequences there could be, like Merapi erupted, and there was that quake near to it as well. Whilst to my knowledge the Volcanoes in the area near the Indian Ocean Tsunami quake did almost nothing after that. Small things have been noticed with large distances from quakes, but never anything really big, so how can we tell?

So yes, I think checking this is a good idea.

Thanks for your answer and comments, Apex.


And keep up the good work!

As you said, we will have to wait and see...

Will keep you updated if I find something unusual.
