Booming dunes roar like distant thunder when dry sand avalanches

On a few deserts worldwide, a dry slip-face avalanche can emit a deep, sustained boom that travelers compare to distant thunder or a low organ note.

Well-sorted, rounded grains sliding together set the dune’s surface vibrating; moisture or mixed sizes often mute the song.

Silence is not the desert’s only soundtrack. Booming dunes prove sand itself can be an instrument when wind and dryness tune it.
