Bif, Bam, Boom

If you've ever worried that you might be on the sharp end of a meteorite strike, check out The Earth Impact Database, which catalogues all known impact craters. There are quite a few. The largest is a little dimple in South Africa 300km across!, and the smallest is a less-dramatic 15m-wide feature in Kansas. In between is the famous Chicxulub crater off the coast of Mexico, the impact of which is thought to have brought the end of the dinosaurs. The thumbnails pictured here are Manicouagan crater in Quebec, Canada, and the famous Barringer crater in Arizona.

You can search by continent: this is the map of Australia, with all the bullseyes marked. Click on any of the splat-marks and you will see more details.
And each of the listings is linked through to Google Maps so you can look at the terrain directly. I love smart websites like this!
