Tips
Red lines are known faults (orange lines are unnamed faults). Thin grey lines are roads. Magnitude = ? for new earthquakes until a magnitude is determined (takes 4-5 minutes). Earthquakes can appear near a fault without having occurred on that fault. To associate an earthquake with a fault requires viewing both of them in three-dimensions. Maps show events recorded in the past 7 days. Maps are updated whenever a new earthquake has been located. Try to reload this page if you do not have the most current map.
