IMAGE 154141
AVO Image

USGS geochemist Christoph Kern collects a gas sample from a fumarole near the summit of Makushin Volcano. In this sampling technique named after esteemed volcanologist Werner Giggenbach, acid gases are dissolved into a caustic solution in the sample bottle, thus allowing the collection of a much greater gas volume than would otherwise be possible.
