Triggered (Induced) Earthquakes
Colorado is world famous for its triggered (induced) earthquakes. Many scientists prefer calling human-caused earthquakes ‘triggered’ rather than ‘induced’, because it is believed that a fault must have stress stored on it, in order for a human activity to release it in an earthquake. A variety of human activities in Colorado have triggered earthquakes during the past half century including chemical fluid disposal, coal mining, reservoir filling, brine disposal, nuclear explosions, and oilfield waterflood.
