Yellowstone volcano: Steamboat Geyser erupts record amount in ‘CHAOTIC’ 2019

Yellowstone Volcano Observatory Chief Scientist Michael Poland said: “This is sort of classic behaviour for a geyser.”

However, Mr Poland conceded for all the opportunities to study Steamboat’s eruptions this year, experts are still unsure what causes it to blow.

He continued: “It gets really chaotic when you get close to the surface.

“There’s nothing definitive that we can tie it to. And, we have some ideas, but it’s very difficult to test them because we don’t have the data that we need, and especially going back in time, lots and lots of data, to really nail down what we think might be happening.
