       This is a 3-D bathymetric map of the southernmost 2/3 of the Loihi summit platform. Three pit craters are the most distinctive features. The southwesternmost crater is a new feature formed during the 1996 seismic event. This crater, named Pele Pit, is roughly 300m deep. It formed in a location that was previously the high-point on the summit, the old Pele's vents area of hydrothermal activity. Adjacent to the New Pit was a breccia field of both fresh and altered pillow lava fragments. Examples of each type, sampled in 1996 using the submersible Pisces V, are shown below:



       Since the pit collapse, hydrothermal activity has resumed in the the pit, forming new chimneys of minerals built up at the places where these fluids issue onto the seafloor. Temperatures of over 200 °C have been recorded within these chimneys.
