Review for eQuakeAlert! by Paul McCarthy
Rated 5 out of 5 stars
Beta version (4.1.1.7) - should really provide a link to the USGS description page for the earthquake if this is where the extension is getting real time information. However it does provide enough info so I can look up the details of the earthquake.
