Ruapehu

Estratovolcán · New Zealand · 2797 m

Ruapehu volcano, seen here from the south, forms a massif composed of at least four overlapping volcanic edifices. Located at the southern end of the Taupo volcanic zone, it contains an active crater lake near the summit. Phreatic explosions have produced mudflows that have affected ski areas on the upper flanks and river valleys below the volcano.

Resumen geológico

Ruapehu, one of New Zealand's most active volcanoes, is a complex stratovolcano constructed during at least four cone-building episodes dating back to about 200,000 years ago. The dominantly andesitic 110 km3 volcanic massif is elongated in a NNE-SSW direction and surrounded by another 100 km3 ring plain of volcaniclastic debris, including the NW-flank Murimoto debris-avalanche deposit. A series of subplinian eruptions took place between about 22,600 and 10,000 years ago, but pyroclastic flows have been infrequent. The broad summait area and flank contain at least six vents active during the Holocene. Frequent mild-to-moderate explosive eruptions have been recorded from the Te Wai a-Moe (Crater Lake) vent, and tephra characteristics suggest that the crater lake may have formed as recently as 3,000 years ago. Lahars resulting from phreatic eruptions at the summit crater lake are a hazard to a ski area on the upper flanks and lower river valleys.

Resumen de Wikipedia

El monte Ruapehu es uno de los volcanes más activos de Nueva Zelanda, en la zona volcánica de Taupo de la isla Norte. Es, además, la montaña más elevada de dicha isla, alcanzando su pico principal una altitud de 2797 m, con los dos picos secundarios de Te Heuheu (2755 m) y Paretetaitonga (2751 m). Está a 23 km al noreste de Ohakune y 40 al sudoeste de la costa sur del Taupo, dentro del parque nacional de Tongariro.
