A Geodetic network in the Novarupta area, Katmai National Park, Alaska
Kleinman JW and Iwatsubo EY. 1991. A Geodetic network in the Novarupta area, Katmai National Park, Alaska. Geophysical Research Letters. 18(8):1517-1519
A small geodetic network was established in 1989 & 1990 to monitor ground deformation in the Novarupta area, Katmai National Park, Alaska. Slope distances & zenith angles for three lines were repeated in 1990. A comparison of the two surveys indicates changes that are within the error of the measurements. Mean mark-to-mark slope distance changes are 1.17 + 1.46 ppm. Two benchmarks were added to the network in 1990 to configure a five-endpoint braced quadrilateral centered about the Novarupta dome.
