This resource provides an abstract. The authors used a dense array of Global Positioning System (GPS) stations to model how the Earth slipped during the 2003 8.0-magnitude Tokachi-Oki earthquake near Japan. Results indicate that displacements of more than one meter occurred in approximately 20 seconds on Hokkaido. It was found that while satellite data are less precise than traditional seismic data, GPS has the advantage in measuring displacement since seismometers cannot distinguish between the ground's acceleration and rotation.
