The new lobe Sinabung, rapidly growing since the last major pyroclastic flow, marked a dangerous imbalance on March 3, 2015, shown in the photo above.

That night, a (partial but important) collapse was accompanied by a large pyroclastic flow that has spread 4.5 km to the south, and forest fires. The plume was approximately 3,000 meters, much higher after the VAAC Darwin.

The penetration of the pyroclastic flow in the Lao river caused a secondary reaction, with a white cloud of steam at the meeting between the pyroclastic flow and the cold waters of the river.
