00:03The Yellowstone National Park is one of the United States' greatest natural wonders, featuring geysers and other incredible beauties.
00:11But the reason for many of the park's remarkable sights is due to the caldera supervolcano that lurks underneath it.
00:16And experts have recently made a pretty interesting discovery about that very volcano.
00:20Scientists have previously believed the conditions under the surface led to around a 10% melt factor for magma.
00:26Now they say that number is likely closer to between 16% and 20%, or nearly twice what was initially
00:31thought to be the case.
00:33So should we start worrying, as an eruption from the Yellowstone supervolcano is likely to change the planet as we
00:38know it?
00:38Not quite, say the researchers, saying in their paper, quote,
00:41Although our results indicate that Yellowstone's magma reservoir contained substantial melt at depths that fueled prior eruptions,
00:47our study does not confirm the presence of an eruptable body or imply a future eruption.
00:52So how much melt would be needed for Yellowstone to go boom?
00:54Experts estimate that previous eruptions occurred when magma levels reached between 35 and 50%.
