Yasur Volcano Temporary Deployment, Summer 2016

The aim of this deployment was to create a dense seismo-acoustic network supplemented by geochemical and visual observation methods to examine Yasur volcano explosions in detail. Some main goals were to examine the directional radiation pattern of volcanic explosions using a novel approach of additional acoustic sensors on an aerostat, conduct high-resolution acoustic source location, and to examine the ballistic hazard associated with explosions. The geophysical deployment consisted of 12 ground-based infrasound sensors (Chaparral model 60), 3 infrasound sensors on an aerostat (BSU-type), and 8 broadband seismometers (Trillium compact posthole). All sensors were digitized using DATA-CUBE by Omnirecs.
