Q: With all of the earthquakes in Nevada recently, it makes me think that Nevada my have a Volcano Brewing! Earthquakes usually in a certain area, occur prior to Volcanoes!
Makes me wonder.
Do you think that this is even possible?
One Answer: No. These earthquakes are not part of a volcanic system or even on a major fault.
Geologists and seismologists are not sure why a system of small faults seems to be growing in seismic intensity. It is possible that it will generate a very large quake but no one really knows what to expect and they could die down without that.
Earthquakes that produce eruptions are only associated with volcanoes and these are caused by lava moving up into the magma chamber of an existing volcano.
Another:
At least one geologist in Nevada says he doesn't think volcanism is causing the quakes due to how shallow the quakes are.
Some of the local geologist admit they don't know what is happening and are more than a little nervous about it.
I wonder if they are keeping quiet regarding any theories that could cause public panic?
It is a volcanically active region that has the potential make things very interesting for the people living there.
Volcanos kill trees near Mamoth.

Why were there many active volcanoes in southern California about 10,000 years ago, but not now?

It seems possible that we may be headed towards a major event.Scott Rowland wrote:
I will give you two hypothesis.
The first one is that perhaps the volcanoes in that region (which part of California you're talking about, I don't know) aren't really extinct. There are a number of volcanoes that have average repose periods between eruptions that are measured in thousands of years. To a human it might seem as if the volcano is dead, but in fact it is just between eruptions.
The second idea is that magma is required to produce volcanoes and the tectonic setting of California has changed from one that produces magma to one that doesn't. Tectonic changes such as these take millions of years to occur though, so I don't think this second hypothesis is very likely.
