The animals are fleeing the area....... Yellowstone is estimated to erupt every 600, 000 years and is ready for another of his monstrous feat. The last eruption was estimated to spew enough ash to bury the State of California under 6 meters of ash; ash covered the whole western states of the USA and a large part of Canada. Projections suggest that such an eruption would be catastrophic to most of the United States, with half the country being “covered in ash up to 3 feet deep,” LiveScience says, adding, “But those same researchers say nothing suggests such an eruption is imminent. They point out, however, that Yellowstone seems to blow its top about every 600,000 years.” Concern over the dangers of the Yellowstone caldera have been renewed recently by a series of hundreds of small earthquakes in the park that began at the end of December. The earthquakes have all measured less than 4.0 in magnitude, and haven’t caused any damage. But increased seismic activity at Yellowstone National Park raises the question: is the supervolcano going to erupt? Scientists say the string of 500-plus tremors that have been felt there in the past week is certainly atypical, according to the Times of London. Furthermore, the floor of Yellowtone’s caldera—a volcanolike formation usually formed by collapsed rock after an eruption—has risen about three inches a year for the past three years, “a rate more than three times greater than ever observed since such measurements began in 1923.”
