I created this mashup about 5 or 6 months ago, but could never put it on my website until I had php5. Now that I’ve made a change to Host Monster, running php5, I can make this script live.
Here is the mashup. It basically puts all of the earthqakes above a 5 in magnitude on the map. It gets its updates automatically from the U.S. Government.
The script encorporates AJAX for the data points, RSS feed parsing for pulling the data from the USGS Earthquake Feed. I used php5’s DomDocument for the xml that is consumed by the Google Map.
