Description

Marine sediment cores collected during the Amadeus and Atacames oceanographic cruises reveal numerous turbidite and ash deposits, which are related to major earthquakes and volcanic eruptions that occurred along the Ecuadorian margin during the Holocene. We provide 14C ages performed on planktonic foraminifera present in hemipelagic layers to constrain the age of turbidite sequences, as well as geochemical analyses of ash layers to identify their source.
