Volcanic Glass Particles

Images 1-5 are of volcanic glass particles fallen in Aberdeen on 24 May 2011 following the eruption of the Icelandic Grimsvotn volcano. The particles were observed using a Scanning Electron Microscope. They range in size from 2 to 3 micrometres to approximately 30 micrometres (1 micrometre = 1/1000th millimetre). Image 6 shows particles from the Eyjafjallajokull eruption in 2010 and is added for comparison.

Additional analysis was carried out on the sample from Lerwick, Shetland on behalf of Scottish Environment Protection Agency (SEPA).
