Earthquakes are measured in several ways: magnitude, intensity, and ground acceleration. The Colorado Geological Survey better breaks down how earthquakes are measured, as well as the most destructive ones that have happened in our state. Colorado's largest earthquake actually occurred just west of Fort Collins in 1882.
