What does that mean?
That is a large burst by fireball standards: the Chelyabinsk fireball of 2013 released about 440 kilotons. If the object was stony rock entering at this speed, it was roughly 5.8 metres across and weighed around 300 tonnes.
Most objects of this kind break up and burn away high in the atmosphere, but larger ones can drop small meteorites. About 70% of Earth is ocean, so most fireballs like this fall into the sea.
