Volcano Infrasound

Welcome to the new volcano infrasound website!

This site serves as a resource for the volcano infrasound community, partially created by the CONVERSE (Community Network for Volcanic Eruption Response) initiative, which stems from ERUPT and SZ4D. Here you will find information including FAQs on volcano infrasound, best practices for deployments, open-source codes and documentation, and more.

Recent Research Highlights

Infrasound from Giant Bubbles

Lyons et al. [2019] describe giant bubbles (radii of 50–220 m) from the 2016-17 submarine eruption of Bogoslof volcano, Alaska.

Infrasound Early Warning

Ripepe et al. [2018] present a scheme for using infrasound array processing to detect and notify authorities of explosive eruption onsets in real time.
