Armand Vervaeck and James Daniell have created a page for cataloging Earthquakes in the US.
These guys do an amazing job of reporting earthquakes and keeping things current relative to seismic events. Take a look:

This page has been created to find out in real-time if an earthquake has been noticed by seismographs in or near the state you are living.
We have started to fill our database in January 2012. On top of the USGS notifications, we are also showing the earthquake details as published by other seismological sources in the world (only for the stronger earthquakes). We list all earthquakes greater than M 2.5 (as this is in average the level that people might feel an earthquake).
We hope that you will describe what you have felt, if an earthquake strikes near you. Your experience is of great interest to the scientific community as a whole.
