Seismometer Installation at Castle Rocks, Denali National Preserve

The National Park Service (NPS) is considering a request from the Alaska Earthquake Information Center (AEIC) (located at the University of Alaska Fairbanks Geophysical Institute) to install a new seismic monitoring station in Denali National Park and Preserve (DENA). This station would be located near the Castle Rocks by the southern edge of the northwestern preserve unit. The proposed seismometer would complement existing seismometers in DENA on Thorofare Ridge and Wickersham Dome and outside DENA at Lake Minchumina and Purkey Pile. These sites are used to monitor frequent seismic activity along and near the western portion of the Denali Fault. Data from the site would be analyzed to improve earthquake detection and hazard forecasting in the region.
