Magnitude 2.5
Date-Time

* Thursday, April 14, 2011 at 02:28:21 UTC
* Wednesday, April 13, 2011 at 07:28:21 PM at epicenter

Location 38.407°N, 118.757°W
Depth 0.9 km (~0.6 mile) (poorly constrained)
Region NEVADA
Distances

* 18 km (11 miles) SW (222°) from Hawthorne, NV
* 23 km (14 miles) WNW (299°) from Qualeys Camp, NV
* 26 km (16 miles) SE (132°) from Wichman, NV
* 237 km (147 miles) E (93°) from Sacramento, CA

Anyone seen this? Army geothermal drilling info (with maps) around Hawthorne, Nevada... interesting...

This document has a map of known faultlines in Mineral County, Nevada: mercurystorageeis.com... and a map of the magazine depot at Hawthorne

Remember the seismologist that predicted a major quake for California at the end of April? While it did not materialize in the predicted time frame, I get the feeling he was only off by a little, this may be the precursor to some major activity in that region.

Hoping I'm wrong of course, really hate to see another major region devastated by seismic activity.

Another 3.0

7 mins later a 2.8 (revised to 3.1)

Guys, there's a reason why it's rockin' and rollin'...volcanic!! Actually, I have a few geologist friends that have been keeping a wary on this location. Of all the volcanoes in California, this one area has vulcanologist worried. Be interesting to see how this shakes out. (No pun intended.)

Here are some links for you guys to peruse.

www.monolake.org...

volcano.oregonstate.edu...

From the link:

Eruptions at the Mono-Inyo Craters volcanic field occurred at 500-year intervals over the past 2,000-3,000 years. The most recent eruption in the region was at Mono Lake between 1720 and 1850 A.D. A dome grew on the lake floor and emerged to make Paoha Island.

offshoot fault from the San Andreas that runs right through this area

Yes I remember that now and the maps I looked
at didn't show it. Any idea what the distance
might be from the tip of the offshoot fault to
the area getting the quakes?

It honestly looks like it;s right on top of it. There look like there are 3 different faults there...more or less a single one through that run straight to that point and end right at HAwthorne.

Yes, I am also more concerned with its proximity to Long Valley than its proximity to the San Andreas. Tectonic quakes in a rather isolated area aren't that concerning, but the idea lingers in the back of my mind that there could be a volcanic connection. Take a look in google earth and you'll see some old craters and basalt flows in the area.

Mag 2.3 in Arizona

That area is pretty shaky.....

They seem to be getting stronger.
Close observation on this one.

reply to post by crazydaisy


Yeah. They certainly don't seem to be trying to go away. Too steady of a shaking for my liking on this one....

Don´t want to fearmonger,but could it be that Cascadia is getting ready to Slip? Probably not,since those Quakes seem to be to concentrated in one Area...

Hey everyone
I just punched in the cords from USGS - 38.391°N, 118.753°W
into google earth & it looks like some mining
in the area. Sorry no pic I can't attach one ATM.
Could this have something to do with it?

Edit: I just noticed the depth of the 4.0 is 6.2 miles.
Is this normal?

I moved to Las Vegas in 1995, stayed until 1999 experienced one small EG a 3.0 in 1999 like 3 am local time...

Well that got all the "ole timers" retired guys sippin scotch in the hotubs...people born and raised there..talkin.

Anyways I kept hearing that Las Vegas valley...was/is an unactive super cauldara sp? volcano..

I got to looking around and yes by looking at topo maps and visually looking around the horizon line the entire area is surrounded by mountains....I think its debatable, maybe confirmed...just had not seen anyone mention this, and I am not sure if it's relevant to the topic here...

Update since Alaska's 3.0

Nevada:

a 3.9 then a

4.0

and another 4.0

within minutes

Could that be related to this link MoorfNZ posted earlier?

Could recent tremors be more practicing?

Cluster atomic bombs?

Nonsense maybe, but plausible to some degree.

Bingo we have a winner,, star for u.

quoted from :www.idealist.ws...

Re-criticality can occur in Nevada as in Fukushima

The startling finding of re-criticality, or the resumption of atomic chain reactions, at the reactors at Fukushima suggest that the same might occur in unexploded or partially exploded nuclear bombs in underground areas of the Nevada National Security Site (NNSS). This inventory of nuclear UXO (unexploded ordnance) includes at least two atomic bomb devices - one damaged during emplacement and another that failed to detonate; two attempts by the Department of Energy in 1979 to use nuclear blast-induced shaking of underground areas to 'destroy' the UXO likely failed. A permanent deployment of radioactive noble gas monitors ringing the NNSS to detect abnormal increases of leaked gaseous fission products at the site could prepare for the possibility of unanticipated nuclear excursions or explosions in Nevada.
