Calaveras fault

Scroll Up

Hollister has its faults … the earthquake kind, that is.

The active Calaveras fault passes right through the city, making Hollister one of only a handful of places where active faulting can be seen at the ground surface in an urban area. All you have to do is take a walk.

You can begin your tour of Hollister’s seismic claim to fame by walking along 6th or 7th Street to Dunne Park. The fault crosses through the park in a north-south direction.

Take a careful look along the sidewalk and curbs of 6th or 7th street. You’ll see they’re shifted to the right. This condition is caused by “right-lateral” strike-slip (horizontal) movement of the fault since the sidewalk was constructed.

Creep along the Calaveras fault is occurring at approximately 7 millimeters per year. A subtle linear hill in the grassy area of Dunne Park marks the location of the fault. The west-facing hill is called a scarp, and it shows that one side of the fault has moved upward relative to the other side. Similar offsets can be observed along many of the east-west streets in town.
