The sound of the implosion was captured on June 18, 2023 by a moored passive acoustic recorder roughly 900 miles away from the deadly event. The brief clip begins with a few moments of relative silence before a deep, sustained rumbling that nears 400 Hz, according to an accompanying frequency graph.
