Figure 1. Map of the Midplate experiment. The explosive source was a 200 m deep chemical blast in the South Paci¢c Ocean
Figure 3. T waves recorded during the Midplate experiment. A shallow 200 m deep underwater explosion has generated hydroacoustic T waves, and seismic T waves have been observed at two seismic stations: DIN on the Mururoa Atoll and FGA on the Fangataufa Ato
Figure 4. Set of diagrams showing wave-front information in a vertical section. Note the high number of geometrical and hybrid caustics found during the hydroacoustic T-wave propagation
Figure 5. The main geological units of the continental slopes at both FGA and DIN are volcanic formations (o p ~3400 m s {1 , o s ~1963 m s {1 , o~2350 kg m {3 ) and carbonate formations (o p ~2800 m s {1 , o s ~1617 m s {1 , o~2270 kg m {3 )
