How big is the biggest geyser in Yellowstone?
How big is the biggest geyser in Yellowstone? Tucked away in the Norris Geyser Basin is Steamboat Geyser, the world's tallest active geyser. Its major eruptions shoot water more than 300 feet (91 m).
What would happen if Yellowstone erupted?
As pressure is released, gases dissolved in the magma come out of solution, turning the magma into a boiling froth. The total energy released would be equivalent to an 875,000 megaton explosion. The shockwave would kill 90,000 people. Most of the lava would fall back into the crater.
Has Old Faithful ever not gone off?
Old Faithful Geyser got its unique name in the 19th century because its eruptions were so regular and predictable. But during parts of the 13th and 14th centuries, the geyser did not erupt at all.
