The Crack of DoomThis is Mount Ngauruhoe, a volcano within Tongariro National Park on New Zealand’s North Island. The peak is a fairly young stratovolcano, built up of alternating lava flows and pyroclastic eruptions with a mostly andesitic composition.The volcano is part of the larger Tongariro volcanic complex and is the largest peak in that group at a height of 2291 meters. It last had a major eruption in 1975, sending out pyroclastic flows that included large blocks of lava that are termed block & ash flows.The volcano has been built over at least the last 2500 years. Written records suggest it has erupted 60 times since the mid-1800s but it has been much quieter since 1975. In 2006 there was a series of earthquakes below this peak, but no eruption took place. It is currently a common target for hikers,but even seemingly quiet volcanic peaks still can host dangers.This peak of course is being featured here in part because of its other role. This peak played the role of Mount Doom in the filming of the movie “The Return of the King”, part of the Lord of the Rings trilogy.-JBBImage credit: Matt Hobbs (Creative Commons)https://www.flickr.com/photos/ultrahi/230061574/Read more:http://www.doc.govt.nz/parks-and-recreation/tracks-and-walks/central-north-island/ruapehu/mount-ngauruhoe-summit-climb/http://info.geonet.org.nz/display/volc/Ngauruhoehttp://www.volcanolive.com/ngauruhoe.htmlhttp://www.gns.cri.nz/Home/Learning/Science-Topics/Volcanoes/New-Zealand-Volcanoes/Ngauruhoehttp://lifeasageologist.wordpress.com/2011/05/08/finding-mt-dome-mt-ngauruhoe/http://www.doc.govt.nz/parks-and-recreation/national-parks/tongariro/features/central-north-island-volcanoes/ -- source link
