Abstract

After the vast volcanic eruption that took place around 1613 BC in Santorini island, Greece, broadly known as the “minoan,” activity continued inside the caldera that was created during historical times, with minor eruptions and lava extrusions. As a result, two new volcanic islands named Palea Kammeni and Nea Kammeni rose from the depths of the sea. These islands are made up of dacite lavas of different known ages. A discrimination of the lavas is attempted using a Landsat-8 satellite image, an air-photo, and light detection and ranging (LIDAR) data. Results are compared to the geological map of the islands. Enhanced satellite images offer a new perspective in mapping lavas of the same mineralogical composition. LIDAR intensity reflectance values generally increase with the age of lavas.
