Understanding volcanic activity through water vapor emissions at Turrialba volcano, Costa Rica


We apply a novel, cost-effective remote sensing method on Turrialba volcano, Costa Rica, which relies on pixel brightness of digital images as a proxy for intensity of light scattered from water vapor emissions. Our data set consists of digital images of the Turrialba volcano crater and gas plume taken every second of the day for September and October, 2016. We found an unreported fire fountain eruption event during the night of September 19 2016, followed by the emergence of outgassing fluctuations over shorter periods than usual at around 100 seconds. The occurrence of shorter periods in the outgassing time series is consistent with magma ascent closer to the surface and could possibly be used as a precursor for some eruptions.
