Abstract
The map is geology around the Hawaiian Islands derived from GLORIA data collected in 1986-1989 from the southeastern Hawaiian Ridge EEZ (Exclusive Economic Zone), which covers more than 1,000,000 km2 of sea floor. The seafloor is characterized by a variety of volcanic and sedimentary processes. Cretaceous age seafloor underlies both subaerial and subaqueous erupted lava forming the Hawaiian Ridge and various Cretaceous seamounts. Subaerial lava quenches and brecciates as it enters the ocean forming smooth slopes. The mobile flanks of the islands have given way into slumps and debris avalanches.
