Yellowstone National Park, which covers parts of Wyoming, Idaho and Montana, is more of a supervolcano could effectively eliminate the United States if it were to explode. The last time he did, there are 640 000 years, he has expelled 240 cubic kilometers (think of it) of rock remains in the sky.
Thursday morning, southern Montana residents feared the worst when a magnitude 5.8 earthquake shook the region. Although the epicenter was located just 230 miles from Yellowstone, the US Geological Survey (USGS) says that seismic activity was not illegal and that the supervolcano should not explode quickly.
“The solution of the localization and focal earthquake mechanism is consistent with the right side fault in combination with defects in Lewis and Clark line, a prominent zone of sliding, sliding and oblique gliding that tends towards north east-southeast of Idaho for East of Helena, Montana, southeast of the earthquake, “the USGS said.
The earthquake, which was the eighth largest ever recorded in Montana and the largest in 34 years, occurs only weeks after a dozen earthquakes hit the region. The swarm of activity began on June 12 and at the end of the month, about 900 earthquakes were recorded near the supervolseur Yellowstone, along the western edge of the park.
Although increased seismic activity has sparked fears of a possible eruption supervolonnement Jacob Lowenstern USGS told Newsweek that is unprecedented.
“The swarm in 2010 on the Madison plateau lasted at least three weeks. In 1985, there was one that lasted for several months,” he said. “Yellowstone has had dozens of such seismic swarms in the last 150 years it has been visited.The last volcanic eruption in the caldera was there 70,000 years.For the magma reaches the surface, it is necessary to create a new vent that requires a large Amount of intense geological activity.
The USGS puts the probability of a volcanic eruption at 1 730 000. Even if an eruption were to occur, it would likely lead a lava flow instead of a cataclysmic explosion. Although this has an effect on Yellowstone, this does not mean the end of the United States as we know it.
The 5.8 magnitude earthquake that shook Thursday morning Montana may have hit dinner and woke up some residents, but the supervolcano was quiet night.
