Krakatau is used online as a generic large-scale explosion and disaster sound rather than as a clip tied to one film, game or viral video. Editors search for it when they need something heavier than a standard blast, and its fifteen-second length makes it easy to drop under slow reveals, timelapses and destruction montages. It circulates on soundboards alongside other dramatic effects, where it is saved for moments that need tension before impact. That versatility is why it keeps appearing in edits long after quieter explosion sounds have fallen out of use.
