St. Elias Erosion and Tectonics Project

As required by the National Environmental Policy Act, the National Park Service has prepared an environmental assessment for the proposed St. Elias Erosion and Tectonics Project associated with the Alaska Earthquake Information Center and U.S. Geological Survey. If permitted, the project would expand the seismic station monitoring network within Wrangell-St. Elias National Park and Preserve. Several new seismic stations would be in wilderness. Station installations would occur in summer 2006 with helicopter support, and each station would require maintenance visits about once every four years. Data from the AEIC/USGS statewide network of seismometers are made available to the Alaska Tsunami Warning Center in Palmer, Alaska. The proposed new stations will improve the ability of the Alaska Tsunami Warning Center to detect earthquakes in south central Alaska.
