The world's largest acidic geyser has erupted in Yellowstone National Park for the first time since 2020. The eruption is reported to have occurred after a period of inactivity, with some outlets specifying the geyser had been silent for 6 years, although the exact duration of the inactivity is not consistently reported. The geyser's eruption has been confirmed by multiple sources, with all agreeing it is the first such event since at least 2020.
