Abstract
The long duration and high frequency of P and S phases from earthquakes along the West Indian island are are deseribed. These phases have been described previously in the literature without explanation. It is shown that the long duration, high frequency, and velocity of both phases can be explained as due to a minimum velocity channel slightly below the M-discontinuity. Other observations are shown to indicate the probable presence of the minimum velocity channel.Keywords
