FAIRFIELD — Vallejo bore the brunt of the damage in Solano County associated with Sunday’s 6.0-magnitude earthquake just a few miles away in Napa County.
Between broken water mains and structural damage, the city late Sunday estimated that the quake caused $5 million in damage to the community. That total was expected to change through the week as more information on damage is discovered.
Proximity matters when you’re talking about earthquakes. Sunday’s quake happened 4 miles northwest of American Canyon and 6 miles south-southwest of Napa, just over the county line from Vallejo, in neighboring Napa County, according to the U.S. Geological Survey in Menlo Park and the Northern California Seismic Center at the University of California, Berkeley.
Solano County, like Napa County, is prone to seismic activity.
The Concord-Green Valley fault is perhaps Solano County’s most noteworthy earthquake zone. There’s a 4 percent chance it could generate a 6.7 magnitude or greater earthquake in the next 30 years, according to the U.S. Geological Survey.
The last monster quake on the Concord-Green Valley fault occurred between 200 and 500 years ago, a USGS report said.
Solano County’s other seismic faults include the Cordelia fault near Rockville, the Kirby Hill and Montezuma Hills faults near the Montezuma Hills and the Vaca fault near Vacaville.
Activity by emergency responders in Solano County consisted mainly of assessing the damage at the local level and providing support to emergency responders in neighboring Napa County.
- The California Highway Patrol reported shortly before 4:30 a.m. Sunday that Highway 37 at Sonoma Boulevard in Vallejo required closer inspection after the earthquake, and that drivers should expect delays in the area. The westbound connector from Interstate 80 to Highway 37 was later closed from I-80 to Highway 29 due to possible earthquake damage, according to the Coastal Transportation Management Center. The connector reopened at approximately 6:20 a.m.
- The CHP reported shortly before 10:30 a.m. that its personnel had inspected all area roadways, overcrossings and bridges within the CHP’s area of jurisdiction. Damage to highways and roads in or near Napa, and just outside of Calistoga.
- Vallejo’s city manager declared a state of emergency in the city as a result of the damage there that included 16 confirmed water main breaks. A stretch of Nimitz Avenue was closed through the morning as a result of the earthquake. At least one building on Georgia Street, with eight residential units, was deemed uninhabitable. A commercial building was evacuated due to structural concerns. A portion of Georgia Street and Indian Alley remained closed late Sunday until the buildings there can be assessed for damage.
- The Red Cross in Vallejo opened an evacuation center at the Florence Douglas Senior Center on Amador Street. The center was closed after everyone there found alternate living arrangements.
- The Solano County Sheriff’s Office and the Office of Emergency Services spent the morning inspecting such areas as local dams and waterways, radio and cellular towers, levees, roads, railroad tracks and bridges, and reported that no significant damage was found. The county’s emergency responders were also dispatched to Napa.
