Robin Matoza uses seismic and infrasonic waves to understand Earth processes, with applications primarily in volcanology. Infrasound is atmospheric sound with frequencies below 20 hertz, which is the lower limit of human hearing. Analyzing infrasound enables him to learn about the mechanisms and dynamics of explosive eruptions and shallow volcanic degassing. He also uses seismology to study magmatic, hydrothermal, and faulting processes occurring within and around volcanoes.

Matoza’s research is centered on understanding the geophysical signatures of volcanic unrest and eruption, which has applications in monitoring and mitigating volcanic hazards. More generally, he is interested in all aspects of infrasound and seismo-acoustics research, including numerous natural and anthropogenic sources as well as infrasound propagation through the atmosphere.
