Did you know that there was a 5.3 magnitude earthquake in Trinidad in 2011?

All 50 states and all U.S. territories are vulnerable to earthquakes.  Most people are surprised to learn that earthquakes occur right here in Colorado.  Even though Colorado is considered a region of minor earthquake activity, many uncertainties exist because of the very short time period for which historical data is available.  Some earthquakes in Colorado occur naturally; some are caused by human actions.  Natural earthquakes occur when two blocks of the earth suddenly slip past one another. Humans can also trigger earthquakes through activities including oil and gas extraction, reservoir impoundment, fluid injection, or mining. 

Earthquakes strike suddenly, without warning, and they can occur at any time of the year, day or night.  Earthquakes can be felt over large areas, although they usually last less than one minute.  During an earthquake, remember to DROP, COVER and HOLD ON. Drop to the floor and get under something for cover, then hold on until the shaking stops.  Explore the information below to learn more about what you can do to stay safe in the event of an earthquake!
