Early in the morning of the 27th, a summit hot spot is seen along with an active lava flow and an ash plume which stretches for several tens of miles. Later in the afternoon of the 27th, periodic bursts of ash and steam rise a few hundred feet above the summit of the volcano. According to sources at the AVO seismic activity is still high. Ash plumes rise 12,000 to 16,000 feet above sea level. Early in the day, lava fountaining and an active lava flow are observed.
Activity subsides later in the day and into the night.
