Abstract

This study explores the use of crowdsourcing to expand volcano monitoring records. A survey of people in Aotearoa New Zealand regarding the sounds heard following the 2022 Hunga Tonga-Hunga Ha'apai eruption revealed observations that aligned well with geophysical records. The crowdsourced data filled gaps in instrumental records, providing insights into the audible frequencies and the wave's interaction with the environment thousands of kilometers from the source. The study demonstrates crowdsourcing as a reliable, low-cost method to supplement traditional volcano monitoring.
