Listening to volcanoes: constraining eruption properties from infrasound observations.
Volcanic activity at all scales generates sound waves in the atmosphere. These sound waves are primarily at low frequencies below human hearing (< 20 Hz) and hence are termed infrasound. By studying the observed infrasound signals we can learn about the properties of volcanoes and eruptions. In this talk I will provide an overview of the volcano infrasound and its utility for volcano monitoring before discussing two modeling projects that attempt to relate infrasound observations to eruption properties.
