Monitoring Entiat Earthquakes in Chelan County, Washington

Entiat, Chelan County is one of the most seismically active regions in Washington. There are no 3-comp stations to record current shallow earthquake activity in the area. Relocation studies have not been successful for this area due to lack of poor station coverage. USGS is suggesting to install more stations to better record the earthquakes in the area (Tom Brocher, written communications). WA DNR- Geology and Earth Resources will install (5-10) rapid deployment stations to record the earthquakes in this area in next 6 months (maybe with extension of another 6 months). This effort will help understand the earthquake activity caused by an active fault that have not well characterized. This active fault have a potential to generate sizable damaging earthquakes in the area.
