A new eruption started at the volcano abruptly Sunday (27 Mar) afternoon at 16:16 local time (00:18 UTC). An explosive eruption with lava fountaining produced an ash plume that quickly rose to approx. 20,000 ft elevation (6 km) and the Aviation Color code was raised to red.

The activity continued and reached its peak over the next 24 hours, when a sustained, continuous ash plume extended more than 700 km (400 miles) to the northeast over interior Alaska, with a maximum height of 37,000 ft (9 km) altitude.
Lava fountaining from the summit crater was observed throughout the night by mariners, pilots, and by residents in Cold Bay, located 37 miles (60 km) to the SW.
Volcanic mudflows (lahars), generated by rapidly melting ice and snow, are likely descending on the flanks of the volcano and could present a hazard in the local river valleys.
Alaska Volcano Observatory recorded continuous strong tremor accompanying the eruption. As of today (Tuesday morning), the eruption continues at much reduced intensity and the Aviation Color code has been lowered to ORANGE.
