Kathy Gibson reports – Scientists have confirmed that a big meteorite exploded close to Gqhberha last week , with witnesses reporting the flash and sound from hundreds of kilometres away.
Most of these are small and are deflected by our atmosphere, but larger meteorites penetrate through the earth’s shield and burn brighter and longer. As they approach the earth’s surface they become more dense and their landing is more impactful. She relates how the story unfolded: “I was out cycling and when we heard the noise we first thought it might be thunder or an earth tremor.”
On Thursday and Friday, they collected reports from eye-witnesses and ear-witnesses, collaborating the flight path and strewn field.Prof Gibson explains that a bolide explodes in a terminal blast and often forms fragments. Much of it is burnt up, but some pieces do get through – in fact, about 10 to 15 meteorites make it to Earth every day.
More than 150 eye- and ear-witness reports show sightings were as much as 600km to 650km apart, with loud booms and vibrations focused along the coast near Gqeberha.CNEOS confirms that the bolide was travelling at 20,1km per second, with energy of 92 tons TNT, and exploding at an altitude of 38km.
