3. Eruptions

3.1. Greece

The Minoan eruption in Santorini.

The Minoan eruption happened around 1645 BC in the Late Bronze Age. It was one of the largest plinian eruptions in younger time. It erupted ca. 30-40 km3 rhyo dacitic magma and is ranked VEI=6 (Volcanic Explosivity Index after Simkin and others, 1981). The eruption was followed by collapse of the magma chamber that enlarged an existing caldera .The height of the plinian eruption column is estimated 36-39 km (Pyle, 1990). It dispersed tephra throughout the Eastern Mediterranean and might have led to global climatic impacts. Its deposits on Santorini consist of up to 50 m thick layers of white pumice and ash. The eruption destroyed an inhabited and culturally high-developed island which perhaps might be the origin of the Atlantis legend as many scientists believe. Since 1969 excavations near Akrotiri have brought to light an important marine Cycladic town famous for its well-preserved and magnificent wall-paintings
