Abstract

A small geodetic network was established in 1989 and 1990 to monitor ground deformation in the Novarupta area, Katmai National Park, Alaska. Slope distances and 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. -Authors
