It seems US is embracing not only for a worsening economic crisis, but also a possible natural disaster originating from under Yellowstone supervolcano caldera. The recent frequent earthquakes happening at Yellowstone National Park [wiki] had alarmed scientists to closely monitor the seismic activities around the area.
CHEYENNE, Wyo. (AP) — Yellowstone National Park was jostled by a host of small earthquakes for a third straight day Monday, and scientists watched closely to see whether the more than 250 tremors were a sign of something bigger to come. Swarms of small earthquakes happen frequently in Yellowstone, but it’s very unusual for so many earthquakes to happen over several days, said 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.”
Smith directs the Yellowstone Seismic Network, which operates seismic stations around the park. He said the quakes have ranged in strength from barely detectable to one of magnitude 3.8 that happened Saturday. A magnitude 4 quake is capable of producing moderate damage.
“This is an active volcanic and tectonic area, and these are the kinds of things we have to pay attention to,” Smith said. “We might be seeing something precursory.
“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.”
A terrific prospect from USNews.com if Yellowstone volcano caldera finally had a deadly spew:
And what if the supervolcano blew? Kind of like if a giant rock hit the Earth. A planet killer. An extinction-level event. Let me quote the words of President Tom Beck (Morgan Freeman) in the comet-hitting-earth film Deep Impact:
Within a week, the skies will be dark with dust from the impact and they will stay dark for years. All plant life will be dead within weeks. Animal life within a few months. So that’s it. Good luck to us all.
God Bless America!
