Description

Sonification of year-long infrasonic records present unique challenges. In this video, infrasonic intensity for ~1.5 years (03-16-2011 17:30 UT -- 08-22-2012 09:30 UT) of eruptive activity at the Halemaumau vent of Kilauea Volcano is distilled, fused with infrared images from USGS and remapped into a classical audio theme. A lot of array processing, statistical sieving, and averaging went into this process, so many of the finer aural details are lost. In general, infrasound intensifies (staccato) during times of transition, and remains steady (bassline) during times of stability. With intriguing exceptions, of course. This work is a collaboration between USGS HVO and the UH ISLA. The IR was provided by Matt Patrick, and Anna Perttu compiled and DQd the array processing results.
