Summary: Pliocene to Pleistocene volcanic sand turbidites recovered 320 km west of the island of Hawaii at Ocean Drilling Program Site 842 contain fragments of fresh, weakly vesicular glass and tests of Pleistocene and Eocene radiolarians. This sand is probably related to turbidity currents generated from debris avalanches produced by giant landslides on the flanks of the Hawaiian Islands. On their way to Site 842, the currents flowed over the ∼500-m-high Hawaiian Arch, indicating that the turbidity currents were at least 325 m thick. Similar sand has been reported 930 km south of the islands. Thus, Hawaiian giant landslides play a significant role in central Pacific deep-sea sedimentary processes.
