Rare Acid Geyser Awakens in Yellowstone: First Eruption in Five Years.

Echinus Geyser Resumes Erupting

According to TSN.ua: After more than five years of dormancy, a rare acid geyser known as Echinus has resumed erupting in Yellowstone National Park (USA). Scientists from the U.S. Geological Survey recorded the geyser's activity on February 7, 2023. This marks the first observed eruption of the geyser since 2020.

Echinus Geyser is known for its bursts of activity, which recur every two to five hours. During an eruption, it shoots columns of hot water up to about 6–9 meters high. Water temperature near the surface reaches roughly 93°C, and the geyser itself is approximately 20 meters in diameter.

Shifts in Geyser Activity

Notably, in the 1970s, the geyser erupted at intervals of 40 to 80 minutes, and during eruptions in the 1980s and 1990s, the water columns reached heights of over 20 meters. However, between 2018 and 2020, only isolated eruption events were recorded, indicating a shift in this natural phenomenon's activity. The resurgence of Echinus is drawing attention from both scientists and tourists, as the geyser is one of the park's rare natural wonders.

This renewed activity may signal changes in the geothermal dynamics of Yellowstone National Park. Such natural occurrences are crucial not only for studying the park's ecosystem but also for understanding the geological processes at work in the region. Given that Yellowstone is home to one of the world's largest volcanic systems, monitoring events like geyser eruptions helps researchers assess potential hazards and environmental shifts.
