South Napa Earthquake
All but one of Napa Valley Unified School District’s campuses will reopen for classes Wednesday after being closed for two days while engineers inspected them for possible damage from Sunday morning’s 6.0-magnitude earthquake near American Canyon, Superintendent Patrick Sweeney announced this afternoon.
There is a 25 percent chance of a strong and potentially damaging aftershock in the next seven days following Sunday’s 6.0-magnitude earthquake near American Canyon, U.S. Geological Survey officials said Monday.
An aftershock of the Napa earthquake, one of dozens of that have hit after Sunday’s 6.0 shaker, was felt Monday afternoon and registered a magnitude of 2.9.
Dozens of downtown Napa buildings have been left uninhabitable by Sunday’s 6.0 earthquake, so how are inspectors supposed to get a true idea of the damage to buildings that aren’t even safe to set foot in? One man thinks camera-equipped quadcopters could be part of the answer.
In just over 24 hours following the 3:20 a.m Sunday earthquake the USGS recorded 124 minor quakes and counting in the area. The seismic activity is clustered around the epicenter and to the north near the Geysers, a region known for regular ground shaking. The largest of the tremors was 3.6 magnitude, just hours after the initial earthquake.
