The sharp-topped summit is ~11 km NE of the summit of Amukta and 35 km W of Yunaska volcano. The visible edifice is steep and strongly eroded. No eruptions have been recorded and its age is not precisely known.
Resumen de Wikipedia
Resumen en inglésChagulak Island is a small, uninhabited volcanic island in the Islands of Four Mountains group in the Aleutian Islands of southwestern Alaska, United States. The 1.9 mi (3.1 km)-wide island consists of a single cone that reaches an elevation of 3,747 ft. Chagulak is a stratovolcano and is separated from the nearby Amukta Island by a channel about 4.3 miles (6.9 km) wide; though the two islands are joined underwater. No eruptions have been recorded and very little is known about the volcano, as the only study done on Chagulak so far is a single chemical analysis of a "low-potassium, high-alumina basaltic andesite" from the north shore.
