New Zealand dormant volcano erupts after a century
A New Zealand volcano dormant for more than a century has erupted, sending up ash clouds, disrupting flights and closing roads. Mount Tongariro, one of three volcanoes in the centre of the North Island, became active just before midnight local time, with reports of loud explosions, spewing rocks and steam. Read more

Dr Nic Peet says that the Tongariro Alpine Crossing, the Tongariro Northern Circuit and the huts on the mountain will remain closed until the risk to public safety has eased. Read more
Small volcanic earthquakes have been recorded beneath Mount Tongariro. The sequence started on July 13, but soon declined, restarting on July 18 and increasing in number on July 19 and 20. These indicate unrest at Tongariro and give reason to change the Volcanic Alert Level to Level 1 and the Aviation Colour Code to Yellow. Read more
It's the composition of the rocks, not elfin magic, that makes New Zealand's mountains some of the steepest on Earth -- without being particularly prone to landslides. A new survey of the mountain ranges that form the spine of New Zealand confirms the steepest are made almost entirely of tough but otherwise unexciting rocks called greywackes and schists.
Mount Ngauruhoe is a 2,291 metres high cone shaped volcano on the edge of the Tongariro massif. The volcano is new Zealand's most active volcano with 61 eruptions since 1839.

The volcano is the `Mt Doom` in the movie Lord of the Rings. It is the youngest vent and highest peak in the Tongariro volcanic complex on the Central Plateau of the North Island, and first erupted about 2,500 years ago. It is technically a secondary cone of Mount Tongariro.

Visitors are being warned not to enter the crater of Mt Ngauruhoe in Tongariro National Park, New Zealand, due to an increase in its volcanic alert level.
The Institute of Geological and Nuclear Sciences says very small earthquakes under the volcano have increased over the past month to up to 50 a day at present. The scientific alert level has been raised from zero to one, which indicates some signs of unrest. Geologist Michael Rosenberg says scientists will be putting more monitoring equipment in, to determine whether rising magma is the cause of the earthquakes. The Department of Conservation is advising visitors to Ngauruhoe not to enter the crater area in case concentrations of volcanic gas have increased there.
The last significant eruption at Ngauruhoe was in 1975, but it has had minor seismic activity since then.
