Abstract

On January 12, 2020, Taal volcano in Philippines erupted, 43 years after its previous eruption in 1977. This eruption was preceded by diffuse CO ₂ degassing precursory signals. Significant temporal variations in diffuse CO ₂ emission from Taal Main Crater Lake (TMLC) were observed across the ~ 12 years reaching high CO ₂ degassing rates in 2011 and 2017, with values typical of plume degassing volcanoes. In addition to these CO ₂ surveys at the TCML, soil CO ₂ efflux continuous monitoring was implemented at Taal volcano since 2016 and a clear increasing trend of the soil CO ₂ efflux in 2017 was observed. These geochemical observations are most simply explained by magma recharge to the system, and represent the earliest warning precursor signals to the January 2020 eruptive activity.
