Karangetang volcano (Siau Island, Indonesia): incandescent lava at summit, alert raised



September 5, 2013 – Indonesia A new eruption could be underway at the volcano. VSI raised the alert to 3 (Siaga, alert) on a scale of 1-4, following the observation of incandescent lava at the summit and glowing rockfalls on the eastern side into the Batuawang ravine. Strong degassing generates a plume rising up to 500 m. Satellite images show a hotspot at the summit as well. These observations suggest that new magma has been arriving at the summit where mild strombolian activity is taking place. If this activity increases, the occurrence of dangerous pyroclastic flows is a likely scenario, similar to what happened at Fuego volcano in Guatemala a few days ago.
