Singkut (Caldera(s)) · last erupted 1881
Tectonic setting: Subduction zone / Continental crust (> 25 km)
The Quaternary Singkut caldera is about 7 x 4 km with the S half of the rim topographically distinct. Post-caldera cones have filled much of the crater and the N rim, including Sibayak, Pintau, and Pratektekan. The 900-m-wide Sibayak crater is partially filled on the north by Pintau. A lava flow traveled through a gap in the western crater wall from the summit lava dome of Sibayak; the active geot…

Current GOES X-ray flux class
Solar wind speed and magnetic field strength indicate current space weather activity. Elevated or storm-level readings can disrupt satellites, GPS accuracy, and power grids. This is a planetary-scale signal, not specific to this location — typical quiet conditions run under 400 km/s wind speed and under 5 nT magnetic field.
