A study of the utility of helium and carbon isotope and abundance variations as a monitor of magma-induced seismic activity was undertaken at Long Valley caldera in eastern California. The principal results of this study was that proximity to magma source and degassing history of that source are crucial factors in determining the sensitivity of the response of helium and carbon to localized seismicity. Further studies are underway to further gauge the response of helium and carbon to seismic events.
