During repose periods, volcanoes can release large amounts of gas as visible (fumaroles, solfataras, plumes) and non-visible (diffuse degassing) emanations. The surface dynamics of gas emissions are usually controlled by local volcano-tectonics and hydrology, as permeable tectonic structures are the main pathways for the transport of gases to the surface. Because CO2 is the major gas species after water vapour both in volcanic fluids and in magmas and is an effective tracer of subsurface magma degassing, diffuse CO2 emissions at volcanoes have played an important role in volcano monitoring.
The goal of this study is to evaluate 2019 diffuse CO2 emissions from the Tenerife NSRZ volcano and compare these value to previous data. The two selected students for this programme will collaborate with field and lab work related to the INVOLCAN’s diffuse volcanic degassing monitoring of Tenerife North–South Rift Zone (NSRZ) volcano, Canary Islands.
During this program students will learn how to:
