Place it at the climax of an eruption sequence, after a slow build and just before the reveal. Follow it with Vine Boom for a second hit, or lead into it with Dun Dun Dun to signal what is coming before the blast.

This short clip captures a volcano in full eruption, with a low rolling roar, cracking rock and a rush of ash and gas building to a heavy blast. It feels tense, ominous and overwhelming, like standing too close to something far bigger than you, and it works best when a moment needs real scale and danger.
