Iliamna volcano (Cook Inlet (SW Alaska)) activity update: increased seismic and fumarolic activity
Thu, 22 Mar 2012, 07:32
07:32 AM | BY: T
Seismicity at Iliamna volcano continues to be above background levels and fumarolic activity and steaming has increased as well.
Satellite images acquired during 9-16 March showed a plume drifting 56 km downwind that was likely water vapor. The report noted that long-lived fumaroles at the summit of Iliamna frequently produced visible plumes, but the current plume appeared to be more robust than usual. Scientists aboard an overflight on 17 March observed vigorous and plentiful fumaroles at the summit, consistent with the elevated gas emissions. Gas measurements indicated that the volcano was emitting elevated levels of sulfur dioxide and carbon dioxide.
