Description: Using continuous pressure records from eight infrasonic observatories around the world, the authors have compiled statistics on infrasound occurrence and on the background noise distribution that affects the detectability of infrasound. With triangulation, the source locations for over 200 infrasonic events have been established. The most frequently detected sources appear to lie in or near certain mountainous regions throughout the world.
