Infrasound and the Seismo-Acoustic Wavefield

Infrasound monitoring is used to detect and study a variety of natural and anthropogenic sources, as well as to probe temporal and spatial variations in the atmosphere. Many infrasound sources occurring above and within the solid earth or hydrosphere also generate seismic waves. This session focuses on coupled seismo-acoustic propagation through the Earth-ocean-atmosphere system. Consideration of the seismo-acoustic wavefield has the potential to both better constrain directionality and location for a variety of geophysical sources such as volcanoes, earthquakes and chemical or nuclear explosions and elucidate a wider variety of propagation phenomena than seismology or infrasound alone. To take full advantage of a seismo-acoustic wavefield over multiple distance scales, new sensor technologies and data fusion schemes are necessary.
 
We invite submissions detailing recent science results and research advances in infrasound, seismo-acoustics and similar multi-phenomenological research. Presentations that explore observations and/or interpretations of seismo-acoustic phenomena, existing and emerging source and propagation models, advances in instrumentation, inversion methods and signal analysis techniques are welcome.
