The lava dome was incandescent at night. Incandescent avalanches from lava-flow fronts traveled as far as 1.5 km E down the Batuawang and Kahetang drainages.
Seismicity decreased, but continued to be dominated by avalanche signals. The Alert Level remained at 3 (on a scale of 1-4); visitors and residents were warned not to approach Karangetang within a 4-km radius.
