Los Angeles is moving

. The Pacific Plate is moving northwestward at the rate of 0.048 meters per year, or about 5 meters every century, slowly carrying Los Angeles towards San Francisco. The North American and Pacific Plates strike and rub against each other like immense grindstones, producing earthquakes along their boundary known as the San Andreas fault. The dated circles denote places where very major earthquakes have occurred with magnitudes of 8 and over on the Richter scale.
