Napa 2016 Seismic Profiles Lines
Satellite image of the Napa Valley in California. Gray area is the City of Napa. Thin pink lines along the west side of the city are surface rupture traces of the West Napa Fault that broke during the August 24, 2014 earthquake. The two lines of red and yellow stars are locations of temporary seismographs that will be deployed for the 2016 survey. Two short turquoise-colored lines crossing the West Napa fault are locations where temporary seismographs were placed in 2014 to record aftershocks.
