Alamagan Island

Alamagan is roughly elliptical in shape, with a length of 4.8 kilometers (3.0 mi), width of 4 km (2.5 mi), and area of 13 km2 (5.0 sq mi). The entire island is the summit of a stratovolcano which rises over 4,000 meters (13,120 ft) from the ocean floor, to an altitude of 744 m (2,441 ft) above sea level at Bandeera Peak, at the north-western edge. The volcano is topped by a caldera, 700–900 meters in diameter and about 370 m (1,210 ft) deep. There are three smaller cones to the north, northwest and south of the main crater. The volcano has not erupted in historical times, but by radiocarbon dating, eruptions occurred in 540 AD and 870 AD, with a potential dating error of around 100 years. These eruptions involved pyroclastic flows and had a VEI of 4. Claims of the most recent historical eruptions are not clear, eruptions might have occurred as late as 1887. Within the main crater and on the western slopes are a number of active fumaroles.
