Digital News Report – Residents of Oklahoma City felt a 4.0 magnitude earthquake today. Within 10-minutes the earthquake was followed by a 3.8 magnitude aftershock.

When you think of earthquakes you don’t think of Oklahoma, but since late Sunday night there have been two pre-shocks measuring 2.8 and 3.3 on the Richter Scale. It is uncertain whether this 4.0 tumbler was a pre-shock or the major quake.

Earthquakes are uncommon in the Rocky Mountains, but the USGS says they do occur. Although the ones along the San Andreas Fault are usually greater in magnitude, earthquakes can be felt all around the United States, including the east coast.
