Elsewhere, as in the Gulf of Alaska, a buried marginal trench has not yet been revealed by seismic stations. In the continental margins of the Atlantic, Indian, Arctic and Antarctic Oceans, and the Mediterranean Sea, the continental rise generally represents the Category III provinces. The Pacific, however, is bounded by an almost continuous line of marginal trenches. The high seismicity, vulcanism and
