Northeast corner of 4th and Locust Streets, looking down 4th Street, in December, 1966. The movement along the fault is causing the standing wall to be slightly bent. Note the effect on the sidewalk, more discernible in the right view. Image Credit: Dr. Edward Berg. SOEST, University of Hawaii Seismic creep is the constant or periodic movement on a fault as contrasted with the sudden rupture associated with an earthquake. It is a usually slow deformation of rock resulting from constant stress being applied over a period of time. Sometimes aseismic slip is observed at the ground surface along a ruptured fault that has produced a substantial earthquake. Examples are from the Hollister and Hayward, California, region. Several of the slides are split images of a location, comparing fault movement over the years. |
