This evening, a 7.0 magnitude earthquake struck California, caused by the movement of tectonic plates under the earth's surface. The two plates that run along the San Andreas fault rubbed against each other until one released, triggering the quake. Most of the population of San Francisco has evacuated, and those still in the affected area are urged to follow officials' orders and watch out for aftershocks. The local news reporter provided this update to inform viewers and direct them to relief organizations like the Red Cross.
