Volcanism at Ruapehu is caused by the subduction of the Pacific Plate under the Australian Plate at the Hikurangi Trench to the east of the North Island. A second, larger lava dome appeared in May, which continued to grow over the following months and had emptied Crater Lake of water by July.. Rock formations that date to this period are collectively named the Te Herenga Formation, and today these formations be seen at Pinnacle Ridge, Te Herenga Ridge, and Whakapapanui Valley, all on the northwestern slopes of Ruapehu. , At 8:16 p.m. on 25 September 2007, volcanic tremor was detected underneath Ruapehu, which was followed at 8:26 p.m. by an explosive surtseyan eruption. GNS Science Reference:  A snow groomer on the Whakapapa skifield narrowly avoided being caught in the lahar there. Here you overlook Crater Lake, and beyond is Tahurangi, the true summit of Ruapehu. An eruption warning system operates in the ski field to warn skiers in the event of another eruption.. Each of these four stages of activity has left behind distinct rock formations, named the Te Herenga Formation (erupted 250,000–180,000 years ago), the Wahianoa Formation (erupted 160,000–115,000 years ago), the Mangawhero Formation (erupted 55,000–15,000 years ago), and the Whakapapa Formation (erupted 15,000–2,000 years ago). The most impressive ones are the volcanoes in the central plateau. The volcano is forested below its line of permanent snow cover. Walk the glaciers yourself by checking out How to Get to Mt Ruapehu’s Crater Lake in Winter. This prevents build-up of pressure and results in relatively small, frequent eruptions (every 20–30 years on average) at Ruapehu compared to other andesitic volcanoes around the world. It was a moderate phreatic eruption, which blasted rocks up to 1 km northwest of the crater and sent lahars down several valleys. Since then, the volcano has built up in four main phases.  The explosive phase of the eruption lasted for less than a minute and blasted ash, mud, and rocks northward, reaching to about 2 km from Crater Lake.  Ash in the Tongariro River also damaged the intake turbines at the Rangipo power station., and ash clouds caused airport closures as far away as Auckland and Wellington. It is 23km northeast of Ohakune and 23km southwest of the southern shore of Lake Taupo, within Tongariro National Park.  In historic times, major eruptions have deposited a tephra dam across the lake's outlet, preventing lake overflow into the Whangaehu valley. , On 5 July 2003, about 350 skiers and 70 skifield staff were trapped on the mountain overnight at Top o' the Bruce when a sudden snow storm blew up and within a few minutes made the access road too dangerous to descend. Bursts of earthquake activity immediately preceded rapid rises in the temperature of Crater Lake, with the surface temperature reaching 51.4 °C in January 1995—one of the highest temperatures recorded in 30 years and about 10 °C higher than its usual peak temperature.  The same storm also trapped an experienced Japanese mountaineer when the weather unexpectedly closed in on him, but he built a snow cave and sheltered in it until he was rescued days later.  A lava dome was observed in Crater Lake on 19 March but was destroyed in a series of explosive eruptions over the following week. New Zealand’s mountains support 3,153 inventoried glaciers, 99.4 % of this number (_99.9 % by volume) on South Island, and the remaining few on Mt. 1. The Mangatoetoenui Glacier on Mt Ruapehu is moving at a generally slow speed of 20m (66ft) a year, which has been calculated thanks to a plane crash that happened in 1952. During the late Pleistocene, a small ice-cap existed on Mt Ruapehu, with a series of small (< 10km-long) valley glaciers radiating out from a dome centred on the summit area (McArthur and Shepherd, 1990). Nearly half of the water in Crater Lake was erupted into the air, which subsequently rained down onto the summit, generating lahars down several river valleys. Although severe weather is unusual and generally forecast, it has claimed several lives over the years, including a party of five NZ Army soldiers and one RNZN naval rating, caught in a week-long storm while undergoing winter survival training in 1990. This southern crater erupted three times, and lava flows from this crater traveled nearly 14 km to the south. The club Tukino field is on the east of the mountain and is open to the public.

The small eruption was marked by a magnitude 2.9 volcanic earthquake and sent waves 4–5 metres (16 ft) tall crashing into the wall of the crater.  Minor phreatic or hydrothermal eruptions occur every few years on average, with notable minor eruptions occurring in 1969, 1975, and 2007. There are 18 glaciers on Mt Ruapehu, but only six sprawl over a hectare or more. , Ruapehu entered an eruptive phase in March 1945 after several weeks of volcanic tremors.  A tephra dam had formed at the lake's normal outlet during the eruptions, which eventually collapsed on 24 December 1953 causing a lahar that led to the Tangiwai disaster with the loss of 151 lives when the Tangiwai railway bridge across the Whangaehu River collapsed while the lahar was in full flood, just before an express train crossed it. In 2000, the Eastern Ruapehu Lahar Alarm and Warning System (ERLAWS) system was installed on the mountain to detect such a collapse and alert the relevant authorities. 4. Mt. The first indication of an eruption was reported on 8 March, with ashfall seen on the eastern slopes. , The first significant eruption took place at 8:05 a.m. on 18 September 1995, raining tephra onto the summit region and sending lahars down the mountain. The other-worldly treasures are hidden away until you get to the rim and then it's all on.

Two climbers were caught in the eruption at Dome Shelter, an alpine hut approximately 600 m from the crater, when the hut was struck by the surge. , Andesitic clasts found 100 km southwest of Ruapehu, near Whanganui, demonstrate that volcanism may have begun in the Ruapehu area as early as 340,000 years ago.  During the Te Herenga stage of activity, magma rose quickly through the crust during eruptions.  A minor eruption occurred on 26 April, which sent waves against the walls of the crater and damaged some monitoring equipment there.
