Experts investigate Galapagos' Volcanoes

Experts from the Geophysical Institute of Ecuador, the University of Cambridge and the Galapagos National Park (PNG) investigated the volcanic activity of Wolf Volcano located in the Galapagos Archipelago, in order to improve the volcanic hazard assessment. In this context, the Geophysical Institute indicated that experts participated last June in a research mission on the eastern flank of Wolf Volcano, in cooperation with the Charles Darwin Foundation. "The aim of this research is understanding how volcanic eruptions in Galapagos are triggered, in order to improve the volcanic hazard assessment in the long and short-term," said the Geophysical Institute of the Polytechnic National School. He detailed that fieldwork was carried out on lava flows emitted during May-July 2015, and also on older flows associated with some eruptive periods of Wolf Volcano. Assisted by a drone, aerial images of lava flows were made in order to produce orthophotos and high-resolution numerical terrain models that estimate the volume of magma emitted during a eruption. He also mentioned that the samples of lava and slag obtained will be analyzed (petrology and geochemistry) at the University of Cambridge to determine the pre-eruptive conditions of the magma and define the configuration of the volcano's feeding system. The archipelago, which owes its name to the giant tortoises that inhabit it, allowed the English scientist Charles Darwin to develop his theory of the evolution and natural selection of species. The Galapagos Islands are listed as Natural Heritage of Humanity by the United Nations Educational, Scientific and Cultural Organization (UNESCO).
