More than 800 million people around the world live at risk of being negatively affected by volcanic activity, yet the number of people living near active volcanoes is increasing every year. On the island of Tenerife we explore how the physical and chemical processes of volcanism and geohazards are shaped by geodynamics and geology. You will develop field skills to reconstruct a geological history based on your own observations. We study the deposits from volcanic plumbing systems to lava flow, catastrophic caldera-forming eruptions, volcanic plumes, explosive magma-water interactions and the evidence of volcanic island collapse. This module helps students understand how the economic benefits and beauty of a volcanic landscape are juxtaposed against the threat of evacuation and loss of life, property and infrastructure.
