About Iyang-Argapura
Iyang-Argapura is a complex rising to 3,088 meters (10,132 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. The volcano has produced 1 recorded eruption.
Geography & Climate
Iyang-Argapura is located in Indonesia, within the Sunda Volcanic Arc of the broader Sunda-Banda Volcanic Regions. Situated at 7.97° S, 113.57° E in the Southern Hemisphere, the volcano lies within a tropical climate zone. At 3,088 meters above sea level, Iyang-Argapura rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Iyang-Argapura sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Indonesia near Iyang-Argapura, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is andesite / basaltic andesite, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
Eruption History Summary
Iyang-Argapura has 1 recorded eruption in the geological database, spanning from 1597 CE to 1597 CE.
GVP Reference Summary
The massive Iyang-Argapura volcanic complex dominates the landscape between Raung and Lamongan volcanoes in eastern Java. Several Holocene volcanic cones are present, and valleys up to 1,000 m deep dissect the heavily eroded basal Iyang volcano. No major eruptions have occurred within at least the last 500 years, although there was an unverified report of an eruption in 1597 CE. Fumaroles occur in some of the many explosion pits found in the summit crater complex.
