In recent years, the Steamboat Geyser has once again captured the attention of scientists following a series of eruptions. Although such unusual behavior hadn’t been observed since 2003, its renewed activity has brought it back into the spotlight.
Located in Yellowstone National Park in the United States, Steamboat is the tallest active geyser in the world. This park is home to nearly half of all the geysers on the planet. Geysers form in volcanic areas and have sometimes been explored as an alternative source of clean energy.
According to previous records, Steamboat hasn’t shown this much activity since 2014. For years, it lay dormant, giving no hint of its ability to shoot water more than 100 meters into the air. Recently, however, it has been making its presence known.
A Noticeable Sign
In light of this activity spike, scientists have issued alerts and begun to observe Steamboat’s seismic data more closely.
Experts clarify that this activity doesn’t necessarily mean an imminent volcanic eruption is imminent in Yellowstone, which spans Wyoming, Montana, and Idaho. Geologist Jake Lowenstern explained to NPR that “the park hasn’t had a volcanic eruption in 70,000 years,” while “geysers erupt all the time.”
Still, Yellowstone is not just any park. Beneath its surface lies a supervolcano with the potential to cause eruptions up to 100 times more powerful than those of an average volcano. Nevertheless, there is no current indication suggesting a real threat. In fact, Michael Poland, head of the Yellowstone Volcano Observatory, confirmed to the Washington Post that “there are no signs of an imminent eruption.”
In any case, Steamboat’s activity could be considered a good sign: it indicates that the hydrothermal system still has water flowing through it. If it were dry, it could mean magma is dangerously close to the surface.
How a Geyser Works
Simple in theory but complex in practice, a geyser erupts when underground water comes into contact with extremely hot rocks. The water heats rapidly, expands, and under pressure, boils explosively (like an uncovered pressure cooker).
In 1904, the Waimangu Geyser in New Zealand set a record of 457 meters. Meanwhile, Steamboat has reached 115 meters, retaining its title as the most powerful active geyser in the world.
