This is a much better visualization of the earthquake data than the static image on the USGS website. Really cool usage of google maps. I wonder if it could do a worldwide map, there probably are a lot more earthquakes in the rest of the world!

The GeoRSS feed from USGS makes doing simple apps showing recent earthquakes pretty simple. Here's one I did a year or so ago: http://swingley.appspot.com/maps/eq

If you zoom out on the example you'll see it already shows the entire Earth.
