Yellowstone volcano: USGS predicts ‘more big LAVA flows’ when Yellowstone erupts

Another 13 lava flows broke out beyond the volcano’s caldera and 40 produced so-called basalt vents – volcanic fissures oozing dark and scorching volcanic rock.

For Yellowstone to undergo another super-eruption in the future, it would need to produce more than 240 cubic miles (1,000 cubic km) of material.

All of that molten rock then needs to concentrate in point, a sponge-like magma chamber, and has to exceed 50 percent of all material in the chamber.

Mr Lowenstern all magma chamber imaging and predictions show there is only around 15 percent of melt in Yellowstone’s chamber, compared to solid rock and crystal.
