The United States Postal Service determined that repairing the building would be too costly and sold it to a developer for $2 million. Field observations and maps were integrated with airborne imagery, lidar, and InSAR to produce a comprehensive, large-scale digital map of fault rupture and zones of ground deformation. The preferred fault model for the 2014 South Napa earthquake has a cumulative seismic moment of 1.28 × 10 18 Nm during its 8 s of coseismic rupture. In Napa, 62 properties remain red-tagged, meaning they are too dangerous to access. This total included repairs made to 144 water mains, repairs or replacement of a compromised water tank in Brown's Valley that is part of the City's water system and repair of 294 locations where streets and sidewalks had been damaged.

The quake damaged many buildings, causing injury to over 170 citizens, power outages, fire hazard, and infrastructure failure. The map, observations, and photo database are summarized here in appendixes and figures and are also available as a series of digital data products within a companion U.S. Geological Survey data release (Ponti and others, 2019); the characteristics of fault rupture and ground deformation features are summarized in detail in the body of this report. The event was then the largest in the San Francisco Bay Area since the 1989 Loma Prieta earthquake, which measured 6.9 on the moment magnitude scale, but was later surpassed by the 2014 South Napa earthquake. Potential-field data indicate that the M6.0 South Napa earthquake and its aftershocks were influenced by complex structure among the West Napa-Carneros-Pinole-Franklin faults system. The Mw 6.0 South Napa earthquake of August 24, 2014, produced complex and extensive surface faulting and other ground deformation features. The results of this compilation reveal that faulting occurred within a 2-km-wide zone on six, roughly parallel traces within the West Napa Fault System. , 24 August 2014 earthquake centered in Napa, California, USA, "M6.0 – 6km NW of American Canyon, California", "Napa quake damage rises to $362 million", Napa, Calif., earthquake: Economic hit could reach $1 billion, "Napa's people, buildings hit hard by 6.0 earthquake", "Boats, grapes and Poseidon at Napa quake's epicenter", "The Mw 6.0 24 August 2014 South Napa Earthquake", "Northern California earthquake is area's strongest in 25 years", "After earthquake near Napa, up to 100 homes labeled unfit to enter", "Strong Earthquake Shakes Northern California", "Napa quake: Obama declares major disaster, freeing up aid", "Earthquake damage repaired, Napa's Native Sons building shines again", Northern California earthquake: Blue-collar Vallejo hit hard, "Earthquake cracks, buckles roads, but leaves bridges OK", "Wine industry tallies spilled wine, shattered barrels", "Napa quakes causes $80 million blow to wine industry, report says", "Napa tallies earthquake damage across city", "Napa earthquake death: 2 weeks later, quake claims first victim -", "First earthquake-related death reported", "Crumbled by Napa earthquake, Uptown Theatre mural rises again", "First Presbyterian church returns to quake-damaged sanctuary after almost two years", "After earthquake repairs, Napa Methodist church to reopen Sunday", "Napa awards repair contract for quake-damaged Goodman Library", "Napa's old post office sold for $2 million for a hotel", "Repair of earthquake damage to Napa courthouse to start soon", "Trefethen rebounds after the earthquake", "Napa quake jumpstarts stream flows, though probably only temporarily", "Surprise bonanza since Napa quake: dry creeks now flowing", "After big quake, Napa fault could move 6 inches in 3 years", "Napa's surprise fault line triggers earthquake study of the region", "Experimental warning system gave 10-second alert before California earthquake", "In Latest Calif.
