What does that mean?
That is a small burst by fireball standards: the Chelyabinsk fireball of 2013 released about 440 kilotons. If the object was stony rock entering at a typical 20 km/s, it was roughly 1.4 metres across and weighed around 4 tonnes.
It penetrated deep into the atmosphere, which makes it more likely that fragments reached the ground as meteorites. About 70% of Earth is ocean, so most fireballs like this fall into the sea.
