The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
An eruption on April 11 ejected a cloud of volcanic gas and ash that reached a height of 20 km (12 mi) and spread over an area of 108,000 km 2 (42,000 sq mi). [10] Pyroclastic flows from the eruption traveled up to 19 km (12 mi) away from the volcano. [11] 3 Bezymianny [12] Russia 2022 15

Two long-dormant “supervolcanoes” on two separate continents appear to be stirring to life. Well, maybe. In recent months, more than a thousand minor earthquakes have rattled the area around ...
The next pre-collapse rhyolite eruption is the Green Canyon Flow in the north of Big Bend Ridge, with a mapped volume of about 5 km 3 (1.2 cu mi), dated at 1.2989 ± 0.0009 million years. [59] Its age is indistinguishable from that of the subsequent Mesa Falls Tuff , but the Henry's Fork Caldera fracture truncates the Green Canyon Flow ...
The INGV recorded 1,252 earthquakes in the Campi Flegrei area in the month of April 2024, most with a magnitude less than 1.0. ... The last major eruption of the supervolcano was in 1538, which ...
