Abstract
Seismic slip extends from maximum expected depth through the crust in 45-75 Ma oceanic lithosphere in the Indo-Australian intraplate region off the Sumatra-Andaman trench. Large (magnitude greater than 7) strike-slip earthquakes in this region can rupture multiple differently oriented faults. Rupture directivity modeling provides tentative support for active east-west oriented faults.
