Physical Sciences: Hekla Eruption Clouds

Abstract

THE black clouds from the eruption in 1965 of the Icelandic volcano Syrtlingur are reported1 to have included as a major constituent particles containing high concentrations of heavy metals, supposedly produced by decomposition of the silicates in the magma followed by vaporization and progressive condensation of the decomposition products. The 1970 eruption of Hekla volcano in Iceland provided an opportunity to determine whether this behaviour is a general characteristic of Icelandic volcanic eruptions.
