Earthquake

The earthquake occurred at a depth of 9.4 km on a northwest oriented fault and occurred through right-lateral strike-slip motion. The epicenter of the earthquake was near the West Napa Fault, a previously unmarked fault.

Damage

Several unreinforced masonry buildings in downtown Napa suffered exterior damage as a result of the earthquake. Sixteen buildings were red tagged following the event and one hundred sixty eight were yellow tagged. Although the magnitude of the primary event was considered only moderate, shaking was intensified in the City of Napa and surrounding area due to the sedimentary soil on the floor of the valley. The earthquake caused an interruption of power to approximately 10,000 Pacific Gas and Electric Company customers. Several hundred houses suffered toppled or cracked chimneys and several instances of broken plumbing due to toppled water heaters were reported. Transportation infrastructure in the affected area did not suffer any significant damage from the earthquake.
