Tongariro

Stratovulcano · New Zealand · 1978 m

Snow-capped Ngauruhoe, seen here from the NE, rises 800 m above its surroundings and is the highest peak of the Tongariro massif. This large massif is located immediately NE of Ruapehu volcano, and is comprised of more than a dozen cones and craters. Frequent explosive eruptions have been recorded from Ngauruhoe since 1839.

Sintesi geologica

Tongariro is a large volcanic massif, located immediately NE of Ruapehu volcano, that is composed of more than a dozen composite cones constructed over a period of 275,000 years. Vents along a NE-trending zone extending from Saddle Cone (below Ruapehu) to Te Maari crater (including vents at the present-day location of Ngauruhoe) were active during several hundred years around 10,000 years ago, producing the largest known eruptions at the Tongariro complex during the Holocene. North Crater stratovolcano is truncated by a broad, shallow crater filled by a solidified lava lake that is cut on the NW side by a small explosion crater. The youngest cone, Ngauruhoe, is also the highest peak.

Sintesi da Wikipedia

Il Tongariro è un vulcano complesso facente parte della zona vulcanica di Taupo, nell'Isola del Nord della Nuova Zelanda. Si trova a 20 km a sud-ovest del lago Taupo ed è la struttura più settentrionale del gruppo costituito dai tre vulcani attivi che dominano il panorama dell'Isola del Nord centrale.
