A new seismic monitoring station in Nicasio received approval from the county last week, part of an effort by the United States Geological Survey to fill the gaps in its expanding earthquake early warning system. Once the station is built later this summer, West Marin residents will be alerted more quickly if a quake hits the area.
The station will be part of ShakeAlert, a warning system developed by U.S.G.S. and a coalition of institutions and agencies. The system, which came online in 2019 and is still being built out, can deliver smartphone alerts to those nearby a few seconds before they feel the shaking from an earthquake.
