| Seismic Creep, USA Images |
 |
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. |
