  • Title: Using 1-Hz GPS data to measure deformations caused by the Denali fault earthquake.
    Author: Larson KM, Bodin P, Gomberg J.
    Journal: Science; 2003 May 30; 300(5624):1421-4. PubMed ID: 12750480.
    Abstract:
    The 3 November 2002 moment magnitude 7.9 Denali fault earthquake generated large, permanent surface displacements in Alaska and large-amplitude surface waves throughout western North America. We find good agreement between strong ground-motion records integrated to displacement and 1-hertz Global Positioning System (GPS) position estimates collected approximately 140 kilometers from the earthquake epicenter. One-hertz GPS receivers also detected seismic surface waves 750 to 3800 kilometers from the epicenter, whereas these waves saturated many of the seismic instruments in the same region. High-frequency GPS increases the dynamic range and frequency bandwidth of ground-motion observations, providing another tool for studying earthquake processes.
