Table S7. Goodness of fit for various arrivals in models to verify the existence of a lower velocity structure extending to a depth of 18 km beneath the Dead Sea Basin. Run06l - Make layer 4 velocity under the basin similar to that in the surrounding areas. Phase RMS(s) Chi Squared Number of Points 41 0.252 6.383 562 42 0.190 3.621 1086 Run06k - Same as Run06l and make layer 3-4 interface flat under the basin. Phase RMS(s) Chi Squared Number of Points 41 0.276 7.634 598 42 0.198 3.940 1088
