53°23'49" N 168°9'58" W, Summit Elevation 3520 ft (1073 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED
Satellite images show discrete plumes with weak ash signals that are reaching altitudes between 20,000 and 35,000 ft and moving E to SE from the volcano. Seismicity continues strongly in a pulsating nature. These pulses are strong enough to be easily identified on seismometers on Makushin Volcano on Unalaska Island. Based on these observations AVO increased the aviation color code at Okmok volcano to red at July 28, 4:51 pm AKDT (20080728/0051Z).
Stronger explosive activity could resume at any time with little or no warning.
