The M w 6.0 South Napa earthquake of 24 August 2014 caused slip on several active fault strands within the West Napa Fault Zone (WNFZ). 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. This is because most deaths from earthquakes are caused by buildings or other human construction falling down during an earthquake. This report is an overview of the lifeline performance.
