    Tectonic Summary

    The magnitude 6.8 southern Sumatra earthquake of October 24, 2007 indicates subduction related thrusting on the boundary between the Australian and Sunda plates. At the location of this earthquake, the Australian Plate moves northeast with respect to the Sunda plate at a velocity of approximately 60mm/yr. The October 24th event occurred within the rupture area of the magnitude 8.4 earthquake of September 12, 2007, which had similar fault slip. Since the September 12th earthquake, this section of the subduction zone has remained very active, producing more than 8 events greater than magnitude 6.0.
