TRAVELTIME TOMOGRAPHY t1 = 3s V1 > 2 blocks (1 m X 1 m) with unknown velocities > 2 traveltime measurements > can you determine ? V1, V2 t1, t2 V2 t2 = 5s V1, V2
t1 t2 = SOLUTION <strong>1.</strong> Solve for V1 using t1 : V1 = 0.3333 m/s 2. Insert in solve for : OR Solve matrix equation 3 5 V2 = V2 = 0.5 m/s 1 0 1 1 1 V1 1 V2
