Being able to detect if an avalanche has released and its path is obviously important for avalanche warning and mitigation efforts. But how do you detect an avalanche? They often happen at night, in poor visibility hopefully far enough away from people.
One way to do that is by using infrasound, the low frequency sound that our human ear can not hear.
In this podcast we talk with Jeffrey B. Johnsen, a professor and infra sound specialist from Boise state university (USA).
If you would like to hear what the avalanches sound like you find the link to the sound from an intense avalanche cycle in Little Cottonwood Canyon (LCC) in Utah, U.S. here
