Repairing deep plaster cracks in ceilings and foundations, anchoring overhead lighting fixtures to the ceiling and following local seismic building standards will help reduce the impact of earthquakes. For example, the South Napa earthquake of August 24, 2014 failed to produce appreciable landsliding in the presence of steep topography despite PGA estimates in excess of 0.5g. 0 February 28 2015 Page 1 1.0 Introduction This report describes the performance of lifelines systems due to the South Napa, M 6.0 earthquake of August 24, 2014. The Napa tremor is the largest to hit the Bay Area since the magnitude 6.9 Loma Prieta event in 1989. The M6.0 South Napa earthquake occurred at 3:20 a.m. on August 24th, 2014. Although earlier earthquakes have been documented—such as significant movement on the southern San Andreas fault all the way back to the 1600s—the earliest reported earthquake in California was on July 28, 1769, noted by members of a Spanish expedition to chart a land route from San Diego to Monterey. Secondary effects of earthquakes sometimes include widespread landsliding where strong ground motions exceed 0.2g PGA, although many earthquakes that generate sufficient ground motions do not have landsliding. Identifying potential hazards ahead of time and advance planning can reduce the dangers of serious injury or loss of life from an earthquake. Through an online survey, interviews, and home inspections, a large amount of new data were collected about the characteristics of Napa area houses and the effects of the quake. Event Overview.
