ACOUSTIC SURVEILLANCE FOR HAZARDOUS ERUPTIONS (ASHE): A PROPOSAL FOR A PROOF-OF-CONCEPT EXPERIMENT

This paper proposes an experiment to test both the practical utility of infrasound as a regional-scale volcanic eruption detection tool, and the feasibility of using such an infrasound system to contribute to the aviation industry timely operational alerts through Volcanic Ash Advisory Centres (VAAC). Ash spewed into the atmosphere from volcanic eruptions poses a major hazard to aircraft operations. In principle, infrasound monitoring will complement both satellite remote sensing and seismic observation to improve continuous monitoring of vast regions of potential volcanic eruption hazard at modest costs. The authors propose a field deployment of several small prototype infrasound arrays in a suitably selected region, sending data in real time to a central data centre where algorithms for volcanic eruption detection may be prototyped. The results will be distributed on a test basis to participating VAACs to compare them with the performance of existing warning systems.
