Christiana-Santorini-Kolumbo Volcanic Field

Talk

IODP Expedition 398 to the Christiana-Santorini-Kolumbo Volcanic Field unearthed one of the largest shallow submarine explosive eruptions from ancestral Santorini: The Archaeos Tuff (AT). This ~90 km3 eruption erupted at water depths of 200–1000 m, forming a megaturbidite up to 150 m thick in the surrounding marine basins. Shipboard biostratigraphic constraints initially suggested an age of...
