The 1950 Meteor Airburst and following Cetacean Deaths

1950, June 21. Australia, Tasmania. Meteor Airburst. Called the “Tasmanian Incident”. Time: Approximately 12:15 AM to 12:30 AM. Described as a violent event. This was a rare, slow-moving bolide that traveled from the NW to the SE, exploding over the Tasman Sea. Reports note that residents as far away as Launceston and the Huon Valley felt the "violent" rattle, over 170km apart. Duration: Witnesses described a slow-moving, brilliant object that took nearly one minute to cross the sky. This long duration suggests a very shallow entry angle (an "earth-grazer"), which allows the shockwave to be distributed over a massive horizontal distance rather than a single point. As it moved toward the Tasman Sea, it culminated in what was described as a "violent explosion" or series of detonations. Residents across Tasmania—from Hobart to the north coast—were jolted awake. Many reported the rattling of windows and a low-frequency rumble that lasted for several seconds after the visual flash had disappeared. Marine Impact High (Acoustic coupling with water).

1950, July 3 (Reported). Tasmania. A 50ft. A dead whale floating bottom up caused a wreck scare. People who saw it about three miles-off Lisdillon.

1950, July 4. Tasmania, Iron Pot / Derwent. 2 Cachalots (Sperm Whales) seen "disoriented" and "unresponsive." Witnesses stated they were "milling aimlessly" near the Iron Pot lighthouse at the entrance to the Derwent. They noted they seemed unresponsive to the noise of passing fishing vessels—a classic sign of acoustic nerve deafness.

1950, July 9. Tasmania, Tasman Peninsula (near Safety Cove/Port Arthur area). A Beaked Whale live-stranded; appeared "exhausted." This date is critical because it represents the "final exhaustion" phase. The animal likely spent the weeks since the June 21 burst unable to dive or feed due to balance (vestibular) failure caused by the airburst's pressure wave. It reportedly made no effort to return to the water even as the tide rose, suggesting total vestibular (balance) failure.

1950, July 15. Tasmania, South Arm. Reports of "large carcasses" seen floating offshore.
