YELLOWSTONE (Worthy News)– Yellowstone is more than twice as big as previously thought according to a leading scientist.
Dr. Smith has been studying Yellowstone’s earthquakes and it’s Super Volcanos for almost sixty years.
He pointed out, “And these giant eruptions, supervolcanos if you wish, probably last many, many months, maybe even years.”
Not only that, they’re huge, thousands of times larger than Mount St. Helens. Smith and his students use siesmographs to map the magma pool underneath Yellowstone’s volcano, and satellites to determine how much the land swells or bulges. They found that the magma is, “2.5 times larger than we had originally imaged.”
The magma movement is signaled by earthquakes. Smith mentioned the 4.8 magnitude Norris area earthquake that damaged Lake Hotel last spring.
He explained, “It’s the biggest earthquake in 30 years.” — Source
