A landslide triggered the 1650 tsunamigenic eruption of Kolumbo in the Aegean Sea

by Dave Petley 27 October 202327 October 2023

The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. In 1650, a destructive tsunami occurred in the Aegean Sea, which is an embayment of the Mediterranean sea, located between the modern Greece to the west and Turkey to the east. There […]
