Independent values of the velocity of P waves have been determined to a depth of 500 km below the New Guinea-Solomon Islands region from an empirical study of the arrival times at the surface from 185 earthquakes. The existence of a low-velocity channel with an axis at a depth of 150 km where P waves may be transmitted at a velocity of 7.6 km/sec, is inferred.
The use of preliminary earthquake epicenters, origin times, and depths of the United States Coast and Geodetic Survey (USCGS), has confirmed the greater reliability of such data since these were determined by electronic computer.
