View of Loihi Seamount looking northwest from a perspective high above and southeast of the Island of Hawaii (green); illumination is from the east. The shield of Mauna Loa Volcano is to the left of top center. Recent mappping of Loihi by Moore and Chadwick identified three landslides that slipped from the seamount's east, west, and south flanks. Each "produced cookie-cutter style amphitheaters reaching nearly to the crest of the volcano, and masses of hummocky debris extending downslope. The extraordinary extent of mass wasting on Loihi has left its rift zones as narrow blade-like ridges that do not display as much of the lobate and hummockly morphology of the other submarine rift zones ridges" from Hawaii's other volcanoes. |
