The spatial distribution of Holocene cryptotephras in north-west Europe since 7 ka:implications for understanding ash fall events from Icelandic eruptions
We present distribution maps for all cryptotephras (distal volcanic ash layers) younger than 7 ka that have been reported from three or more lakes or peatlands in north-west Europe. All but one of the tephras originates from Iceland; the exception has been attributed to Jan Mayen. We find strong spa...
