Degassing plume at Kīlauea in 2013

Detailed Description

At left, the degassing plume at Kīlauea in 2013 as seen by a standard, visible-light camera. Note that plume is mostly transparent, with some blue/brown tones from aerosol scattering, and hard to distinguish from background cloud. At right, the plume from the same vantage point as seen by a UV camera. The SO2 in the plume absorbs UV and makes the plume appear dark. USGS photos by C. Kern.
