Meteor airburst shows how devastating they can be when they occur over the ocean

Small Airburst in Australia. It's incredible to think that it was only 82,000 kg/TNT. What if it had been in the millions, or even just in the hundreds of thousands? Then imagine this over water and above cetaceans. The one off the coast of Mexico on March 27 was 2.4 million kg/TNT. 

2025, April 21. Australia, New South Wales, near Queensland border at the Gibraltar Nature Reserve. Airburst. Coordinates: (29.1 South, 151.6 East). Travelling NW or NNW was seen from Melbourne in Victoria to Bundaberg in Queensland, over 1600 km apart. Colour: Blue-Green. Energy: e = 2.3 × ^10j. -e = 0.082 or 82,000 kg/TNT. Altitude: 41km. Velocity: NA. Time: 09:27 UT, 19:23 AEST. The sound had delayed and concurrent properties. The sonic boom was heard at Stanthorpe (NSW) 58km away and was described as “a massive boom”. At Sandy Flat, houses were shaken shortly after the meteor exploded. A witness stated they, “saw the flash from lounge room window and shortly after heard a big bang, shaking the house like bad thunder”. 

The trajectory in the map below is preliminary.
