22. Comparison & integration and Value Added products Pre-Izmit earthquake velocity field of the Marmara region. Map of GPS velocities relative to Eurasia and 95% confidence ellipses in the Marmara region for the pre-Izmit earthquake period (1988–1999) and location of the trans-NAF profile. Dashed lines show the width of the profile which includes the segment of the NAF that broke in the M = 7.4, 1999, Izmit, Turkey, earthquake (heavy, segmented line). Profile-normal velocity components and 1 sigma uncertainties plotted versus distance along profile. Profile-parallel velocity components and 1 sigma uncertainties plotted versus distance along profile. Coseismic and postseismic (first 75 days) displacements (black arrows) of GPS sites relative to ANKR. L eft figure shows map of Izmit region showing GPS sites and observed (including 95% confidence ellipses) and modeled (yellow arrows) horizontal co-seismic displacements relative to a station in Ankara. Right figure shows map of observed post-seismic GPS station displacements (black arrows) relative to ANKR during the first 75 days following the earthquake. Error ellipses indicate 95% confidence intervals.
