Overview

The basaltic-to-andesitic Pulosari stratovolcano at the western end of Java lies south of the 15-km-wide Pleistocene Danau caldera. The summit contains a nearly 300-m-deep crater open to the ENE with active solfataras on its wall. It is SW across a low saddle from the higher Karang volcano, which was constructed on the SE rim of Danau caldera.

Regional Volcanic Activity
The Sunda-Banda Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

The small circular, forested volcano at the center of this NASA International Space Station image (N is to the top right) is Pulosari. The stratovolcano has a nearly 300-m-deep summit crater with fumaroles along its walls. The volcano lies SE of the 15-km-wide Pleistocene Danau caldera, whose northern and eastern rims and light-colored floor are visible at the upper right.
