Английская Википедия:East Molokai Volcano
Шаблон:Short description Шаблон:Infobox mountain 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 [[Molokai|MolokaШаблон:Okinai]] in the U.S. state of Hawaii.
Description
The East Molokai has a width of Шаблон:Convert and a length of Шаблон:Convert. 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, [[Lanai|LānaШаблон:Okinai]], West Maui, East Maui, Penguin Bank and [[Kahoolawe|KahoШаблон:Okinaolawe]], that formerly constituted the island of Maui Nui.
The highest point is the peak called Kamakou on the southern rim, at Шаблон:Coord.[2][3] The [[pepeopae|PēpēШаблон:Okinaōpae bog]] is just below the rim.[4]
The northern flank of the volcano has been truncated by enormous cliffs rising Шаблон:Convert 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 Шаблон:Convert into the sea, and generated a Шаблон:Convert-high megatsunami that inundated the rest of Molokai and severely damaged the surrounding Hawaiian Islands before eventually reaching the coastlines of California and Mexico.[5]
