Fumarolic emission from Chiginagak volcano on the Alaska Peninsula. This is a long-lived side of steam and volcanic gas emission, but in late September 2014 there was an apparent increase in temperature and perhaps flux from the fumarole. This resulted in a more robust cloud, visible from space by satellite, detectable quantities of sulphur dioxide, and what appears to be a melt channel in the surrounding glacier. No regional earthquakes have been detected, although AVO does not maintain any seismic stations near this volcano and very small events may have gone unnoticed.
