Abstract
The 2010 Eyjafjallajökull summit eruption (Iceland) produced large
amounts of fine ash, disturbing air traffic across the North-Atlantic
and within Europe. Mössbauer spectroscopy of ash-samples and a
lava-bomb has been performed to study the material properties and to
gain insight into why the volcano produced so vast amounts of fine
grained material. Time series of ash samples reveal a changing ferric
to ferrous ratio and level of crystallization which can be related to
the different phases of the eruption. The lava bomb has a much lower
ferric to ferrous ratio, implying that this relatively high ratio for
the ash is a result of oxidizing phreatomagmatic steam explosions.
