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 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. Tens of thousands of people ...
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.
On October 19, 2024, the summit crater of the volcano exhibited continuous degassing, along with occasional weak ash emissions. PHIVOLCS recorded twenty-eight instances of ash emissions, ranging from four minutes to one hour and eighteen minutes in duration, producing grayish plumes that rose 300–800 m (980–2,620 ft) above the summit and ...
He said police will strictly enforce a no-entry regulation in a 4 -kilometer (2.4-mile) permanent danger zone around the 2,435-meter (7,988-foot) Kanlaon, the highest peak in the central Philippines.
The Philippines sits along the Ring of Fire, a 25,000-mile (40,000-kilometer) arc of seismic fault lines around the Pacific Ocean that hosts more than half of the world’s volcanoes.
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
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 ...
