Yellowstone National Park has been experiencing numerous tremors over the past week... Is this the end of mankind when the Yellowstone Caldera blows its top?

Since Dec. 26, about 400 temblors have rumbled under the park, centered under the northern end of Yellowstone Lake. The small quakes Friday registered up to a magnitude of 3.5.
Swarms of small earthquakes happen frequently in Yellowstone, but it's very unusual for so many earthquakes to happen over several days, says Robert Smith, a professor of geophysics at the University of Utah.
"They're certainly not normal," Smith said. "We haven't had earthquakes in this energy or extent in many years."
"Could it develop into a bigger fault or something related to hydrothermal activity? We don't know. That's what we're there to do, to monitor it for public safety."
Smith said it's difficult to say what might be causing the tremors. He pointed out that Yellowstone is the caldera of a volcano that last erupted 70,000 years ago.
Yellowstone has had significant earthquakes as well as minor ones in recent decades. In 1959, a magnitude 7.5 quake near Hebgen Lake just west of the park triggered a landslide that killed 28 people.
I recently watched a program on the End of the World scenarios and this was one...... And I think NBC did a special Docu-drama on this a few years ago,,,,
So if it blows.... It's been nice.... At least this would knock the Brett Favre soap opera off the headlines... That might be worth it...
