Continuous Volcano Monitoring Using a Field-Portable Helium Isotope Detector
The injection of magma into subvolcanic magma reservoirs is one of the most significant triggers of volcanic eruptions. It is often manifested by an increase in CO2 emissions and in the helium isotopic ratio (3He/4He) measured in discharged gases. Temporal variations of helium isotope ratios in volcanic gases preceded eruptions at Ontake Volcano in Japan (September 2014) and at Etna Volcano in...
