Tphases from underwater explosions off the coast of Israel

T phases from underwater explosions off the coast of Israel were recorded at three temporarily installed seismograph stations. The T waves propagated as sound waves through the water with a velocity of about 1.53 km/sec, possibly in the so-called SOFAR channel. Three phases, constituting T, have been identified. These were traveling along the land path as P, S, and/or surface waves, with velocities of 2.5 km/sec and lower. Analysis of the maximum amplitudes and the durations of these phases, indicate low Q values for the material along the land path of the T phases. The quality factor, Q, of the sea water seems to be more than 10 times higher than that of the land. Relatively high scattering in the measured travel times, amplitudes, and durations reflect the structural and geological complexity of the region.
