One thing that worries scientists is a small meteor—maybe 15-20 feet wide—that survives most of the entry into the Earth’s atmosphere then suddenly explodes a few thousand feet above the ground. Such an explosion could result in a blast with the equivalent explosive yield of several thousand tons of TNT and could cause tremendous damage in the unlikely chance it explodes of a city.
That sounds like the Tungusku scenario. If a small chunk hit Nicaragua, it could have been a small companion to the larger asteroid that gravity pulled away. I’m surprised no light streak was reported.
