Map of the GEONET dense GPS receivers network where the location of the epicenter of the Tohoku Earthquake is marked by a star. The polar view of the elevation and azimuth angles of the GPS satellites from 5:30 UT to 8:30 UT as seen by receiver 0979 (shown on the map) is plotted in the inner panel. The dots indicate the satellite geometry at the seismic origin time.
