See What’s Shaking: Earthquake Mashup
The U.S. Geological Survey (USGS) provides excellent data on earthquakes around the world. And, since they make it available as GeoRSS, it’s a popular example for maps. So, it was a natural to include in my book, as one of the five example mashups in the final chapter.

Rather than simply overlay the GeoRSS, I chose to provide icons that helped visualize an earthquake’s magnitude. And, since some parts of the world have more seismic activity than others, I provided a means to snap zoom to the hotspot zones.
If you’re looking to recreate this mashup, you’ll want these image files to make it happen:
Hi, I'm Adam. I'm writing a book about developing maps on the web. This site is where I'll share the things I find and help you create your own maps. 
I am glad I found your site. These are some great working mashups. I like to be able to point people to live examples like this to give them an idea of what can be done nowadays.
