Kanlaon has a peak elevation of 2,465 m (8,087 ft), although it is reported as 2,435 m (7,989 ft) in some sources, with a base diameter of 30 km (19 mi), and is dotted with pyroclastic cones and extinct craters lining to the north-northwest. Just below and north of the summit is the active Lugud crater.
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
The Philippines' Kanlaon volcano erupted for nearly four minutes, shooting ash 2.5 miles into the sky and prompting the emergency evacuation of some 87,000 people.
On June 3, 2024, PHIVOLCS raised the alert level of Kanlaon from alert level 1 to alert level 2, indicating increasing unrest after an explosive eruption occurred on its summit vent at 6:51 p.m. PST. The eruption produced a voluminous and incandescent plume that rose 5,000 m (16,000 ft) above the vent and a probable short pyroclastic flow of ...
The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed.
Of the world’s roughly 200 impact craters, 31 are located in Canada. Quebec itself has 10 other known impact sites. In the presentation to the Meteoritical Society, Rochette showed how the ring ...
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).
