Steam and ash emission from solfatara field

On 10 March at about 1200 MarkAir pilot Jerry Chisum observed ash and steam emission from a solfatara field on the SSW flank (at 56.00°N, 159.81°W). The steam dissipated within 2 km of the solfatara field, but a grayish-brown ash horizon extended about 15 km N at 1,800 m altitude. On 17, 22, and 26 March Chisum made close observations of the region and noted only normal steam emissions. No previous eruptions are known in historical time.
