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 Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory , Ottawa, under the direction of Carlyle S. Beals . Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
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.
The catastrophic June 1991 eruption, which formed a caldera, later filled by a crater lake, had global environmental effects. Mount Bulusan in Sorsogon; Mount Kanlaon and Mount Talinis in Negros; Mount Arayat in Pampanga; Mount Iriga and Mount Isarog in Camarines Sur; Mount Mariveles and Mount Natib in Bataan; Mount Malindig in Marinduque
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 ...
