Do avalanches make noise?

The “whumph” noise is a warning sound that an avalanche may be imminent. It occurs when a deep layer of light, fresh powder piles high atop a dense layer of frozen ice beneath it. The whumph noise is the sound of that powder compressing, shifting or sliding a bit downhill. That’s how avalanches get started.
