Massive Volcano That Is Under Yellowstone Park Has Record Number Of Geyser Eruptions

Underneath Yellowstone Park is a massive supervolcano that if it blows up will severely incapacitate the US. It is believed that the “mouth” of this volcano is or is near the Old Faithful Geyser.

In light of the recent California earthquakes, the geyser has experienced a record number of eruptions:

The world’s tallest active geyser — whose major eruptions shoot water more than 300 feet into the air — is known to be unpredictable. But if there was ever a year to witness Steamboat’s spectacular surge of water, this might be it.

We’re just over halfway through 2019 and the Steamboat Geyser has already erupted 25 times, according to the US Geological Survey. That puts it on track to surpass last year’s record of 32 eruptions — the largest number ever recorded in a year. The record before that was 29 eruptions in 1964.

The Steamboat Geyser erupted seven times just last month alone, the USGS said. June’s outbursts, which occurred on the 1st, 7th, 12th, 15th, 19th, 23rd, and 28th, also smashed the record for the shortest interval between eruptions

Scientists aren’t sure what’s behind the recent increase in activity, but the short answer is that this is just how geysers work.

“They’re mostly random and experience phases of alternating eruptive activity,” Michael Poland, the USGS scientist-in-charge of the Yellowstone Volcano Observatory, wrote in an email to CNN. “So while fascinating, it’s not unusual, nor cause for concern.”

The Steamboat Geyser has experienced periods of more frequent eruptions in the past. The geyser saw an uptick in eruptions in the 1960s after being dormant for about 50 years, and also saw increased eruptions in the 1980s.

Some scientists have attributed increases in Steamboat’s eruptions to thermal energy shifts caused by earthquakes.

But there is no clear correlation between the geyser’s eruptions and earthquake activity, according to the National Park Service.

“The dynamic nature of this geyser basin, and the geology of Yellowstone as a whole, keeps everyone guessing,” the National Park Service says on its website.

Until 2018, the Steamboat Geyser had been mostly calm for about 15 years.

Yellowstone National Park is home to about 10,000 hydrothermal features, including hot springs, geysers and mud pots, the National Park Service says. It has about 500 geysers as well as the largest concentration of active geysers in the world. (source, source)
