A small, explorable slice of NASA/JPL CNEOS reports: bright meteoroids that detonated in the atmosphere, many over empty ocean, a few over cities, all measured in kilotons of TNT.

The source is the public NASA/JPL Center for Near Earth Object Studies (CNEOS) Fireball and Bolide Reports, which list date, location, altitude, velocity and estimated impact energy for atmospheric asteroid impacts observed by U.S. Government sensors and other systems.
I chose it because it makes the “space hazard” problem feel both intimate and planetary: a city-shaking event like Chelyabinsk sits in the same table as dozens of invisible blasts over the Pacific, the Southern Ocean and Antarctica. The data below is an inline representative sample, not the full archive.
