I remember reading somewhere that there are various active faults that criss cross the Las Vegas Valley, and there is one particular fault near Frenchman Mountain, that if conditions are right, could cause a quake large enough to level the entire city

Oh wow certainly don't want that!

I never worry about the 'big one', overhere in New Zealand we're well overdue for the 'big one' but I don't let it get to me.

Am always interested in all the faults and what not in CA and NV and what they're doing.

the most noticible is driving west on ALTA between Decatur and Upland...that hill isn't just a hill

The Walker-Lane fault system which is the most eastern part of the San Andreas fault system runs from Reno to the Boulder Dam. This Fault has moved in the Las Vegas Valley before as a strong quake and the evidence is the Decatur Uplift that you encounter when you drive west along Sahara or Charleston. This uplift is a vertical fault displacement of at least 100 vertical feet. The springs at the Springs Preserve are caused by water moving up this fault to the surface. I can see evidence in the street in front of my house (cracked asphalt) that the earthquake in Wells also occurred here in Henderson but at a much lessor strength. I suggest you expect more earthquake activity in the Las Vegas Valley during the next two years. We have been lucky and soon our luck will change.

A 6.0 magnitude earthquake struck Nevada on Thursday, the U.S. Geological Survey reported.

The quake, centered 15 miles southeast of Wells, Nevada, struck at 7:16 a.m. PST, with a shallow epicenter of 3.7 miles.

Do you mean Walker LAKE fault?

Why do you think there will be earthquake activity in the next two years?

Once or twice, I've seen in the news that there may have been a slight trimmer, but nobody felt them. We did feel one that was in California a few years ago, but that's the only one I've ever heard and felt, or had anyone else say they noticed.

You're right though, we have been lucky, and we could have an earthquake sometime. Do you happen to know when the last one was?

Dont you remember Buzzard.....we were both there for it.....

Poor Wells! When I was doing my rural Nevada trip in May, being in Elko and so close by, I was curious to see how they were recovering from that nasty quake they had in 2008.

There was barricades up and down the streets downtown, didn't look like they were doing anything to restore the town. Some empty motels I saw leaving town. Very sad and pathetic.

I got the feeling that this poor town has given up!

The USGS records earthquake activity every day for the California-Nevada area. They post their findings on earthquake maps that can be seen by logging onto the USGS and the associated websites. The most major fault adjacent to Frenchman Mountain was key to the uplift that caused the mountain to reach its current height. Should this fault move (resulting in an earthquake) there would be a fairly large seismic event that would shake the Las Vegas valley strongly. I am aware that a great deal of the housing construction in the Las Vegas valley is wood based with stucco covering and has a heavy tile roof. Such would not do well if an earthquake were to cause the ground to move back and forth sideways. When an earthquake hits the Las Vegas valley with any strength (4 to 6 on the Reighter scale used by the USGS) it will cause such swaying. There could be a lot of homes damaged. The probability of such an earthquake of this magnitude hitting the Las Vegas valley within the next 2 to 4 years is greater than 35% (per the USGS local office). The new PBS television facility has been built earthquake proof because of this prediction.
