The East Molokai Volcano, sometimes also known as Wailau for the Wailau valley on its north side,[1] is an extinct shield volcano comprising the eastern two-thirds of the island of Molokaʻi in the U.S. state of Hawaii.

Description

The East Molokai has a width of 70 km (43 mi) and a length of 150 km (93 mi). It is overlapped by the West Molokai, Lanai and Haleakalā shield volcanoes. Its shield formation began two million years ago and ended 1.5 million years ago whereas its postshield eruptions occurred 1.5 to 1.3 million years ago. The pahoehoe shield volcano of the Kalaupapa Peninsula postdates the main shield volcano of East Molokai and is considered to represent the last volcanic phase of East Molokai.[1]

East Molokai was one of the seven principal volcanoes along with West Molokai, Lānaʻi, West Maui, East Maui, Penguin Bank and Kahoʻolawe that formerly constituted the island of Maui Nui.

The highest point is the peak called Kamakou on the southern rim at Lua error in package.lua at line 80: module 'strict' not found..[2][3] The Pēpēʻōpae bog is just below the rim.[4]

The northern flank of the volcano has been truncated by enormous cliffs rising Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). from the sea. The sea cliffs were formed when the northern third of the East Molokai Volcano suddenly collapsed and slid off into the sea, about 1.4 million years ago. The landslide was so fast and powerful that it extended Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). into the sea, and generated a Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). high megatsunami that inundated the rest of Molokai.[5]
