About Poco Leok
Poco Leok is a stratovolcano rising to 1,675 meters (5,496 feet) in Indonesia's Sunda-Banda Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Poco Leok is located in Indonesia, within the Sunda Volcanic Arc of the broader Sunda-Banda Volcanic Regions. Situated at 8.68° S, 120.48° E in the Southern Hemisphere, the volcano lies within a tropical climate zone. With a summit elevation of 1,675 meters above sea level, Poco Leok is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Poco Leok in western Flores Island consists of a heavily dissected edifice with a central 3-km-wide central caldera-like depression of uncertain origin. No pyroclastic-flow deposits are associated with the volcano, which is poorly known geologically (Casadevall, 1989, pers. comm.). There is andesite lava within the crater area, which Mahon and others (1992) attributed to the volcanic group immediately north. Volcanism is of Quaternary age (van Bemmelen, 1949), and four fumarole fields are located at elevations of 825-1,200 m within the depression. The Ulumbu geothermal field is located on its flank at 650 m elevation and includes hot springs, fumaroles, mud pots, and steaming ground.
