Naturally occurring sources of infrasound Free

There are growing numbers of potential applications for infrasonic observing systems. The evolving International Monitoring System for the nuclear test ban treaty (including 60 infrasonic stations) offers exceptional opportunities to make infrasonic data sets widely available and to explore their uses in geophysical studies. This is especially true because of the ability to perform synergistic studies with seismic and hydroacoustic systems in a processing environment where diverse data sets can be readily melded. Natural infrasound sources such as avalanches, earthquakes, geomagnetic activity, meteors, ocean waves, severe weather, turbulence, and volcanoes offer great resources for international cooperative research programs. Sources of low‐frequency sound from civilization processes offer a set of parallel opportunities. This paper will review the broad range of investigations possible using both individual and multiple infrasonic observing systems, as well as infrasonic systems in combination with other remote sensing systems.
