Summary & Purpose
Open-vent volcanic systems with active degassing are particularly effective at producing infrasound that exhibits resonant tones controlled by the geometry of the volcano’s crater. Changes in the infrasound character can thus provide constraints on a crater’s lava level, which may vary dynamically in the lead-up to an eruption. Here we show that the increasing frequency content and damping characteristics of the resonant infrasound at Volcán Villarrica (Chile) relate to lava lake position in its crater/conduit preceding its 2015 eruption. We model the acoustic response of Villarrica’s crater to determine that the lake began to rise on February 27th and reached the flared upper part of Villarrica’s crater before oscillating during the two days prior to the March 3rd paroxysm and 1.5 km-high lava fountain. This study demonstrates the utility of remote infrasound monitoring for future eruptions of Villarrica and other analogous open-vent volcanoes.
