According to the U.S. Geological Survey, there have been 3,678 earthquakes in the United States during 2011 as of October 10th. The USGS estimates that there are several million earthquakes worldwide each year, but many go undetected because of their remote locations or lack of magnitude.
The USGS also detects about 50 mine blasts each business day and maintains a separate explosion list -- just to keep the two straight.
No earthquake of a magnitude 3.5 or greater has occurred in my beloved State of Texas in the past thirty years. Now, if you want to talk about hurricanes, we've got you covered.
