Newsweek • • science
Key Points:
- The Echinus Geyser in Yellowstone National Park erupted for the first time since 2020, with activity resuming in early February and eruptions occurring every two to five hours by mid-month.
- Known as the largest acidic geyser on Earth, Echinus features mildly acidic waters caused by a mix of acidic gases and neutral groundwater, with eruptions reaching 20 to 30 feet and lasting two to three minutes.
- Historically, Echinus erupted frequently in the 1970s through the 1990s, sometimes blasting water up to 75 feet, but it has remained dormant at times since then; recent eruptions provide new data on geyser activity cycles.
- Scientists use temperature monitoring to predict eruptions,
