Loihi Survey

The Loihi Seamount survey covers the summit and rift zones, but not the steep flanks of the volcano. Lower resolution surveys of the entire seamount are presented by Fornari et al. (1988) and Moore and Chadwick (1995). The new data show that there are few cones, none of which are flat-topped, on Loihi’s rift zones compared to the rifts of the other surveyed volcanoes. 

The 1996 collapse pit in the southwestern part of the summit platform (1996 Loihi Science Team, 1997; Davis and Clague, 1998) is clearly seen, as are the two older collapse pits. The 1996 pit, with a volume of about 0.17 cubic kilometers, probably formed in response to magma withdrawal to feed an eruption down the south rift zone (Davis and Clague, 1998), although the eruption site has not yet been located.
