FACT: Earthquakes are sudden rolling or shaking events caused by movement under the Earth's surface. An earthquake is the ground shaking caused by a sudden slip on a fault. Stresses in the earth's outer layer push the sides of the fault together. Stress builds up and the rocks slip suddenly, releasing energy in waves that travel through the ...Information available includes the age of the most recent activity on each fault segment, surface rupture areas, and whether or not the faults are visible at the surface.
