New Zealand - December 9th, 2010

The large, dark blue lake in the center of New Zealand’s North Island is Lake Taupo. It is actually the water-filled caldera of a large rhyolitic volcano.

South of the Lake Taupo is Mount Ruapehu, an active stratovolcano at the southern end of the Taupo Volcanic Zone. Here, its peak, the highest point on the North Island, appears capped with snow.

New Zealand - July 30th, 2010

The two main landmasses visible here are New Zealand’s North Island (above) and South Island (below). The two are separated by the Cook Strait.

Of note on the North Island are Lake Taupo, the dark blue lake in the center of the island, and several volcanoes: Mount Taranaki/Egmont (on a peninsula on the western side), Mount Ngauruhoe (south of Lake Taupo), and Mount Ruapehu (south of the former).

Of note on the South Island are the Southern Alps, the snow-capped mountain chain running down the backbone of the island, the sediments near the Banks Peninsula (central east coast), and the bright blue glacial lakes of the Mackenzie Basin (between the mountains and the southeastern shoreline).

This FAPAR image shows the Fraction of Absorbed Photosynthetically Active Radiation of New Zealand‘s North Island. The northernmost tip of the South Island is also visible at the bottom left.

In FAPAR images, the color spectrum over land runs from red (1.0), to green, to yellow and white (0.0), while bodies of water, such as Lake Taupo in the center of the North Island, appear blue. Green to dark red areas indicate the presence of good to high photosynthetic activity, while yellow areas indicate low activity.

The history, climate and geology of New Zealand have created a great deal of diversity in New Zealand’s vegetation types. The main two types of forest have been dominated by podocarps and southern beech. In the north of New Zealand the podocarp forests were dominated by the ancient giant kauri. These trees are amongst the largest in the world, holding the record for the greatest timber volume of any tree; unfortunately, most of these trees were felled.

The remaining vegetation types in New Zealand are grassland of grass and tussock, usually associated with the subalpine areas, and the low shrublands between grasslands and forests.

North Island’s Mountain Chain, from Mount Ruapehu to East Cape, New Zealand – December 20th, 2009

The volcanic summit of Mount Ruapehu, lower left quadrant, is covered in snow in this image of New Zealand‘s North Island. The large body of water north of the volcano is Lake Taupo. North Island’s main mountain chain appears as a dark green area running northeast from the volcano and lake towards East Cape, in the upper right quadrant of the full image.

One of the ranges in this mountain chain is the Kaweka Range, located in inland Hawke’s Bay between the city of Napier, 55 kilometres to the southeast, and Lake Taupo, 50 kilometres to the northwest. It is the source of many rivers which flow into Hawke Bay, including among them the Tutaekuri, Mohaka, and Ngaruroro Rivers.

Volcanoes Near Lake Taupo, New Zealand

New Zealand - November 13th, 2009

Several volcanoes are visible near Lake Taupo, the large lake at the upper right, in this orthorectified image of New Zealand’s North Island. Following the Tongariro River, one of the lake’s main tributaries, upstream from the lower end of the lake, one comes to a smaller lake known as Lake Rotoaira.

Between these two lakes is Mount Pihanga, a 1325m volcanic peak on the North Island Volcanic Plateau. Another smaller body of water, Lake Rotopounamu, is at the north-west foot of the mountain. Mt. Pihanga and Lake Rotopounamu are part of the 5,129ha Pihanga Scenic Reserve, which in 1975 was added to the Tongariro National Park.

South of Mount Pihanga is Mount Tongariro, a volcanic complex located 20 kilometres to the southwest of Lake Taupo. It is the northernmost of the three active volcanoes that dominate the landscape of the central North Island. This volcanic massif, often simply referred to as Tongariro, has a height of 1,978 metres.

The volcano consists of at least 12 cones; Ngauruhoe, while often regarded as a separate mountain, is geologically a vent of Tongariro. It is also the most active, having erupted more than 70 times since 1839.

Continuing south of Ngauruhoe is Mount Ruapehu, an active stratovolcano at the southern end of the Taupo Volcanic Zone. It is 23 kilometres northeast of Ohakune and 40 kilometres southwest of the southern shore of Lake Taupo, within Tongariro National Park.  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).
