View of Lo`ihi Volcano on the southeast flank of Mauna Loa
Image of Lo`ihi derived from topographic and bathymetric data compiled by J.G. Moore and W.W. Chadwick.

View of Lo`ihi Seamount looking northwest from a perspective high above and southeast of the Island of Hawai`i (green); illumination is from the east. The shield of Mauna Loa Volcano is to the left of top center.

Recent mappping of Lo`ihi 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 Hawai`i's other volcanoes.
