Recent Earthquakes in the Intermountain West.

The supervolcano Yellowstone Caldera, considered as an active volcano, covers a 25 mile by 37 mile area of Wyoming. During its last big blast about 640,000 years ago, a large crater was formed in the area. After the big blast, the supervolcano averages 30 minor eruptions. The most recent eruption of the supervolcano was 70,000 years ago that produced the areas’ flat landscape.

Scientists noticed in 2004, that the Caldera‘s ground rises at the rate as high as 2.8 inches (7 centimeters) annually.

3.3 is bupkis...but if it is a precursor....we are DOOMED

"According to geologists however, the Yellowstone caldera itself is unlikely to experience large earthquakes because the weakened bedrock is less likely to burst due to high subsurface temperatures."

Gee that is reassuring /not

High subsurface temps and a weakened bedrock - EQUAL BIG BANG!

In alot of places a 3.3 is called ‘settling’.

If the Yellowstone caldera blows it’s lights out for everyone except maybe about 10K people around the globe, if that.

2012 is fast approaching...

3.3 is nothing. I can fart that magnitude. :-)

We often have these type of earthquakes. I’m surprised it made the news. The 1959 quake was a different. All of my family & friends have a “this is where I was” story on that one. I’m glad I missed that one (not born yet).

[Mr. K]

wasnt there about a 3.3 in Japan before the 9.0?

It’s just Yogi Bear doing the Cha Cha.

Caldera blowing would be a perfect end to today.
