Not sure the source for location or elevation. The peak is much higher than 1,210 m (3,970 ft) acording to either GNIS or Pukui. I think the coords are of the historical village on the coast. Might better to use the rough center of the caldera or something like that. W Nowicki (talk) 20:30, 12 November 2010 (UTC)
The coordinates and elevation are from the book "Volcanoes of North America: United States and Canada", which is used a as a source in the article. Volcanoguy 12:37, 7 November 2012 (UTC)
I oppose the recent move to East Molokai Volcano. If this article should be renamed East Molokai Volcano I suggest Mauna Loa be moved to West Molokai Volcano, Haleakalā be moved to East Maui Volcano and the West Maui Mountains be moved to West Maui Volcano. Just because the USGS prefers East Molokai Volcano does not mean Wailau is not an appropriate name even though there is a valley of the same name at the volcano. Is the valley named Wailau notable enough for an article? If not then it was unnecessary to move the article title to East Molokai Volcano. There are no Hawaiian volcano articles other than this one that use "XXXX XXXX Volcano" as its title. Volcanoguy 02:22, 4 February 2014 (UTC)
It's a matter of WP:COMMONNAME. The volcano on Maui is almost always called Haleakalā. The volcano on East Molokai is almost never called Wailau. I think you're relying on a single source for the name Wailau, a 2001 book on the volcanoes of all of the US and Canada. The only other source I can find which used the name Wailau for the volcano is a 1920 report by Powers, cited in this 1976 USGS report at page 3. I suspect that the authors of the 2001 book used the 1920 report, but it seems pretty clear that the use of Wailau to refer to the volcano is more or less obsolete. Note that the 1976 report had to gloss the term Wailau to clarify that it referred to the East Molokai volcano. I'd go with the USGS as the better source. It's also called East Molokai Volcano in academic sources here, here, here and here.
On the other hand, if you look on Geonames you will find that Wailau there refers there to the abandoned populated place (or to the ancient administrative division), not to the volcano. If you search Google for Wailau, Molokai you will find many references to the valley, the beach, the stream and the trail which led to the valley, and little or nothing about the volcano. I think you would find that on Molokai people would get very confused if you referred to the volcano as Wailau.--Mhockey (talk) 03:34, 4 February 2014 (UTC)
