Over the last 250 years, the earth has experienced more than 90 volcanic tsunamis, accounting for about 25 percent of all fatalities directly attributable to volcanic eruptions.

At the source, volcanic tsunamis can exceed tectonic tsunamis in wave-height. The recent “orange” alert in July 2015 at the Kick ‘em Jenny submarine volcano off Granada in the Caribbean Sea highlighted the challenges in characterizing the tsunami waves for a potential submarine volcanic eruption.

At a December 12 AGU talk, a team of Georgia Tech researchers, including notable tsunami expert Hermann Fritz, will discuss modeling volcanic tsunamis at the NHERI-OSU wave basin.

The team deployed a novel volcanic tsunami generator to simulate submarine volcanic eruptions with varying initial submergence and kinematics. Learn about the team’s modeling technique and results. The measured volcanic eruption and tsunami data validate and advance three-dimensional numerical volcanic tsunami prediction models.

The talk is part of the AGU discussion in the field of natural hazards.
