Increased activity was recorded by PHIVOLCS in September, starting with a series of volcano-tectonic earthquakes on September 9. [13] On September 10, Kanlaon produced its highest volume of sulfur dioxide emissions since 2009, at 9,985 tonnes, prompting PHIVOLCS to raise concern over its possible first magmatic eruption since 1902.

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 ...
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 .
The Centre of Volcanology and Geological Hazard Mitigation recommended that a 7 km (4.3 mi) radius around the volcano be evacuated. [75] Seven villages were affected by the eruption. [76] A larger eruption occurred on 7 November. [77] On 8 November, the volcano erupted several times, one bearing an ash plume with a height reaching 10 km (6.2 mi ...
The last time Campi Flegrei erupted was in 1538, and one of the system’s biggest explosions occurred around 39,000 years ago.. In September, the former head of the Vesuvius observatory at Italy ...
Tejeda Caldera, Gran Canaria, Spain; 13.9 Ma; the 80 km3 eruption produced a composite ignimbrite (P1) of rhyolite, trachyte and basaltic materials, with a thickness of 30 metres at 10 km from the caldera center [71] Gran Canaria shield basalt eruption, Spain; 14.5 to 14 Ma; 1,000 km3 of tholeiitic to alkali basalts [72]
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 ...
