Not to shamelessy bump my own thread, but we need some input from the volcano people.

I live in New Mexico, and know my Geography pretty well, and well lets just say that New Mexico's own supervolcano is no joke.
The Valles Caldera went VEI-7 1.15million years ago.
It is mentioned in this arcticle, on wikipedia en.wikipedia.org...
"
So any way, these eq's 4 of them, biggest a 3.1 happened today, very close to said supervolcano.
Doom.

Valles Caldera is one of the smaller volcanoes in the supervolcano class. The circular topographic rim of the caldera measures 19 kilometers (12 miles) in diameter. The caldera and surrounding volcanic structures are the most thoroughly studied caldera complex in the United States. Research studies have concerned the fundamental processes of magmatism, hydrothermal systems, and ore deposition. Nearly 40 deep cores have been examined, resulting in extensive subsurface data.en.wikipedia.org...

The best way to get the attention of an actual volcanologist is to leave a comment on the Eruptions blog:
bigthink.com...
The latest post is usually the best place. I'll be watching this one.
Out of curiosity is there a geothermal plant there or are they possibly fracking for natural gas?

I guess you would be referring to these 4 quakes?

Interesting that the Smithsonian talks about a low velocity area under the caldera, which would indicate molten rock perhaps.
Now it is also a fact that there are not that many quakes in the areas. This is the list for the past 365 days:

The activity seems bunched in three areas
I don't really believe that 4 quakes over several days is anything to be concerned about at a caldera that has not seen an eruption for 50-60,000 years. Obviously because of the thermal springs it is not extinct, only dormant, but I think you would be seeing very considerably more activity if it was about to awaken.

Gas and Oil production do take place in two of the areas of quakes, including the latest batch of 4 so that may well be the reason. You can see the last 4 quakes right on the edge of the Gas and Oil extraction areas which I have overlaid onto the map of the quakes.
The bunch in the North West corner is not explained by this. It is by the Northern Sangre de Christo fault, but not really any closer to that than the current quakes. If I get time I must investigate that more closely.

You are the exact person I was hoping to show up!
Thanks for your input!
There is a considerable amount of gas/oil production in the Northwest, and Southeast corners of New Mexico. And pockets randomly throughout the state. There are a lot of quakes over by Carlsbad, in the Southeast.
The only thing that concerned me was that the 4 quakes yesterday were in fact very near the Valles Caldera otherwise known as the Valle Grande. It seems that it might be the first step in that bad boy waking up. I'm definitely not saying it is going to blow any time soon, but there haven't been any eq's next to that caldera that I can remember.

Curious indeed, but no I don't believe it is a sign of the caldera waking up. I will see if there is any GPS data available for the area however.

Yeah, in my memory it hasn't been active at all, however I haven't really been paying attention for that long, maybe 5 years.
