The volcanic eruption series at the Sundhnúksgígar crater chain began on 18 December 2023, with an initial eruption that lasted for three days. [ 8 ] [ 9 ] [ 10 ] This eruption was preceded by land uplift in the Svartsengi area, which subsequently deflated upon eruption, indicating the accumulation of magma at a depth of 4–5 km (2.5–3 mi ...
In recent months, more than a thousand minor earthquakes have rattled the area around the Campi Flegrei volcano in southern Italy, stoking fears that it may soon erupt again after nearly five ...
2023 20 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
Since 2011, the volcano has been at the level II (Waspada) of a four-tier alert system set up by the Volcanological Survey of Indonesia.

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 .
Experts fear the volcanic region of Campi Flegrei, or the Phlegraean Fields, near Naples could be reawakening after generations at rest.
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time. Numbers indicate millions of years before ...
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 ...
