A geyser hiding under Yellowstone National Park recently reawakened. But don’t worry: That doesn’t mean the supervolcano beneath the park will erupt soon, a new study finds. 

In March 2018, following a 3.5-year-long nap, Steamboat Geyser suddenly erupted, spewing steam, mud, sand and rocks into the air. The previously dormant geyser erupted 32 times in 2018, a record-breaking 48 times in 2019 and another 48 times in 2020 (its previous record of 29 eruptions was set in 1964), the U.S. Geological Survey reported Monday (Jan. 4).
