I've given my Earthquake Mashup yet another overhaul. And another URL, please update your bookmarks and links.
After finally finding another provider for live earthquake data, it was time to add a selector within the application to switch between different feeds. So now you can choose between data from the USGS, EMCS and GFZ. See the help page for more information and what these acronyms mean.
With the ugly status bar at the top of the page gone, I think this now truly looks like a Web 2.0 application.
