Title

Acoustics of Volcanic Eruptions

Abstract

Volcanic eruptions, and the ash produced by such, have the potential to cause problems to air travel as well as to the environment in general. Our goal is to detect the quantity of volcanic ash ejected into the air through acoustical measurements. Infrasound sensors, as in the world-wide infrasound network, can detect volcanic eruptions. The question now is how do these acoustic signals relate to the strength and ash content of the eruptions. Our method is to use scale-model explosions to measure acoustic intensity, sound power and directivity. We are making preparations to participate in research with the University at Buffalo New York. Our goal is to correlate the acoustical measurements with the depth of the crater and the strength of the explosions.
