An Analysis of Three New Infrasound Arrays Around Kīlauea Volcano

By Weston A. Thelen and Jennifer Cooper

Thumbnail of and link to report PDF (10.4 MB)Abstract

A network of three new infrasound station arrays was installed around Kīlauea Volcano between July 2012 and September 2012, and a preliminary analysis of open-vent monitoring has been completed by Hawaiian Volcano Observatory (HVO). Infrasound is an emerging monitoring method in volcanology that detects perturbations in atmospheric pressure at frequencies below 20 Hz, which can result from volcanic events that are not always observed optically or thermally. Each array has the capability to detect various infrasound events as small as 0.05 Pa as measured at the array site. The infrasound monitoring network capabilities are demonstrated through case studies of rockfalls, pit collapses, and rise-fall cycles at Halema‘uma‘u Crater and Pu‘u ‘Ōʻō.
