Scientists don’t know what caused the usually dormant geyser to erupt 3 times in the last 2 months. They say the recent eruptions of the world’s tallest geyser, Steamboat Geyser in Yellowstone National Park are not a sign that the caldera below is about to go supervolcano.

“There is nothing to indicate that any sort of volcanic eruption is imminent,"

-Michael Poland, U.S.G.S. Yellowstone Volcano Observatory

That said, they are increasing their monitoring via satellite, seismometers and temperature gauges to track this geyser that can shoot scalding hot 300-degree water into the air.

“The Yellowstone caldera is literally a bomb buried in our backyard that will one day go off and wreck the neighborhood, we just don't know when.”

If and when this caldera does go off, it would dwarf the eruption we saw of Mt. St. Helens in 1980.
