South Napa Earthquake Links: USGS event page. The earthquake's epicenter was a few miles south of Napa Valley's renowned wineries, and the quake busted barrels and bottles of precious vintages. The Data Map displays earthquake damage and impact observations from EERI field teams and other contributors using EERI's Photo Upload … Gov. [31] 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. [29][30] A $1.75 million contract to repair damage to the Goodman Library was awarded in January 2017 and work on the building is expected to be completed in early 2018. One person died September 5 as a result of injuries from the quake. Please tell us about your experience. Open-File Report Several wine storage facilities also suffered damage and loss of property. 3:20 a.m.: The time the earthquake rattled residents awake across the region. The South Napa earthquake produced rare fissures. Maximum coseismic slip was greater than 40 cm and possibly as great as 60 cm, with the slip maximum located about 10 km north of the epicenter. 1 . The South Napa earthquake of August 24, 2014 caused the strongest shaking in the San Francisco Bay area since the 1989 Loma Prieta earthquake, 25 years earlier. Many streams and springs, which were dry or nearly dry before the 2014 Mw6.0 South Napa earthquake, started to flow after the earthquake. The developer plans to turn the building into a hotel. [11] The earthquake was the largest earthquake in the Bay Area since the magnitude 6.9 1989 Loma Prieta earthquake. Disaster relief: South Napa Earthquake. Firefighters were hampered in their efforts to fight this fire by a broken water main. [9] At least six of the injuries were classified as critical. Stability of rapid finite-fault inversion for the 2014 Mw6.1 South Napa earthquake Yong Zhang1, Rongjiang Wang2, and Yun-Tai Chen1,3 1School of Earth and Space Sciences, Peking University, Beijing, China, 2Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences, Potsdam, Germany, 3Institude of Geophysics, China Earthquake Administration, Beijing, China Governor Brown declared a state of emergency on August 242, and President Obama declared the South Napa Earthquake a major disaster on September 11, 20143. 10-20 seconds: The length of the earthquake, which hit about six miles south of Napa… 2014 South Napa Earthquake to refine and improve the survey. Another 900 to 1,000 properties have yellow tags. [18], Following the first round of building inspections by the City of Napa inspectors, a total of 613 structures had been tagged; 113 were red-tagged and 500 had been yellow-tagged. 0 . 64, No. Scientists have gathered at the USGS headquarters in Menlo Park to review the effects of the South Napa Earthquake. COVID-19 holiday risk: The safest and most dangerous activities . about viewing, downloading, and printing report files can be found here. LockA locked padlock The disaster was declared on September 11, 2014. Governor Brown declared a state of emergency on August 24, 2014 2. 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.

Earthquake warning systems could potentially give people time to take cover in the event of a quake, preventing injuries caused by falling debris, automatically stopping trains or shutting off gas lines. The M6.0 South Napa earthquake occurred on August 24, 2014. The West Napa Fault transfers slip between a group of related faults (including the Concord Fault and the Calaveras Fault) called the Contra Costa Shear Zone, which was assigned a maximum slip rate of 1mm/yr in the third Uniform California Earthquake Rupture Forecast. $ 362 million in August 2017 browser may not display or print intended!
