The expertise on ultra-high resolution remote sensing surveying with UAV by ZEPHYRUS/P&M research team, especially under extreme environments, lead Gonçalo Vieira to collaborate in the project MEGAWAVE – Unravelling the hazard potential of tsunamis triggered by volcanic flank collapses, lead by Ricardo Ramalho (IDL-ULISBOA). The objective of the field work was surveying relict coastal deposits in Sal Island. The campaign was very successful despite the challenging permament strong winds that prevail from November to May in Sal Island. It is great to work in the Tropics!
