59.3633°N 153.4333°W, Summit Elevation 4134 ft (1260 m)
Current Level of Concern Color Code: ORANGE
Seismic data indicate that eruptive activity continues intermittently and has changed little in character or intensity over the past 24 hours. Ash clouds to altitudes greater than 15,000 ft. above sea level have not been observed on National Weather Service radar since 06:21 AKST on January 30 (15:21 UTC). Eruptive activity occurring now is characterized by low-level explosions, block-and- ash-flow style pyroclastic flows, and sustained production of ash. This type of activity is likely to continue for hours to days.
Further explosive activity producing ash clouds to altitudes over 25,000 feet may still occur with little or no warning. AVO is monitoring the situation closely and the observatory is staffed 24/7. Please refer to our hourly updates and information releases for the most up-to-date status of volcanic activity.
