Mt Egmont/Mt Taranaki

My first view of  Mt Egmont from the Wanganui to New Plymouth road.  It really is an amazing sight and is visible from almost everywhere in the vicinity of New Plymouth. Mount Taranaki, Mount Egmont, or simply Taranaki is an active but quiescent stratovolcano. The 2518-metre-high mountain is one of the most symmetrical volcanic cones in the world. There is a secondary cone, Fanthams Peak, on the south side.

Ruapehu

On the day before I arrived in Taupo, Martin, Wendy and the children went up above the snowline on Ruapehu (pronounced Rua paywho). That is something I have yet to experience.

Mount Ruapehu, or just Ruapehu, is an active stratovolcano at the southern end of the Taupo Volcanic Zone. It is 40 kilometres southwest of the southern shore of Lake Taupo, within Tongariro National Park. The North Island's major skifields and only glaciers are on its slopes.

Ruapehu is one of the world's most active volcanoes and the largest active volcano in New Zealand. It is the highest point in the North Island and includes three major peaks: Tahurangi (2,797 m), Te Heuheu (2,755 m) and Paretetaitonga (2,751 m). The deep, active crater is between the peaks and fills with a crater lake between major eruptions.

It figures quite frequently in our news bulletins. At least it did when I was last here because the water level behind the dam was rising and a lahar or mudflow was expected. There had been a major one in 1953 which had caused the loss of 151 lives. Since then warning systems had been put in place. The lahar occurred on 18 March 2007 - a week after I had left New Zealand. No lives were lost.

The last major eruption took place in 1995 although there have been smaller ones since; the latest being in September 2007 which occurred without warning and injured one person.

Earthquakes, Volcanos, Landslips and Tsunami

New Zealand is a land of magnificence and beauty; a land of awesome landscapes, from glaciers, fiords, mountains and volcanoes to plains, rolling hills, subtropical forest and sandy beaches. It is also a land of geological excitement; a land of earthquakes, volcanoes, landslips and tsunami.

I felt my first earth tremor in New Zealand (leastways the first one I realised was an earthquake) last February. Now I know what is meant by the question "Did the earth move for you?" It did exactly that and it was a very odd feeling! Everyone will tell you that the first time is odd. They are correct. I filled in the report on the earthquake website we have in New Zealand. After a while the 'quake appeared on the site:
http://www.geonet.org.nz/2691968g.html . The funny thing is that it's not the least bit scary. This one was over in a second or two anyway. And houses here are built for earthquakes and are not like UK houses at all.

I'm sure that over the next six months I will be mentioning things like Mt Ruapehu (a 'local' active volcano), thermal springs, earthquakes and much more. I hope that I never mention a tsunami. You can find out more about New Zealand's active geology at GeoNet.

If you would like more information on the geology of New Zealand an excellent site is Geology - An Overview from the Te Ara Encyclopedia of New Zealand.
