Fig. S4. Snapshots of the sea surface elevation during the first 1500 s of the Indian Ocean Tsunami for the full rupture, and the Southern and Northern ruptures for Model 2. The evolution of the tsunami from offshore of Sumatra and along the island chains of the Nicobar and Andaman islands is evident. Red indicates an elevated sea surface, blue a depression. Note the tsunami waves radiating outward from the southern section of the fault and those originating from the northern section of the rupture.
