New Zealand - December 22nd, 2011

This orthorectified image shows the Tauranga Harbour (upper left quadrant, top), Lake Rotorua (rounded, bottom center) and Lake Tarawera (smaller, right of former) on New Zealand’s North Island. The harbour is the location of the Port of Tauranga, New Zealand’s largest export port.

Lake Rotorua is the second largest lake in the North Island of New Zealand by surface area, and covers 79.8km2. With a mean depth of only 10 metres it is considerably smaller than nearby Lake Tarawera in terms of volume of water. It is located in the Bay of Plenty region. The city of Rotorua is sited on its southern shore, and the town of Ngongotaha is at the western edge of the lake. The lake was formed from the crater of a large volcano in the Taupo Volcanic Zone.

Lake Tarawera is the largest of a series of lakes which surround the volcano Mount Tarawera in the North Island of New Zealand. Like the mountain, it lies within the Okataina caldera. It is located 18 kilometres to the east of Rotorua, and five kilometres to the west of the mountain. The lake’s surface area is 39 km².

New Zealand - March 27th, 2011

This orthorectified image shows a cluster of lakes on New Zealand’s North Island. The largest visible here is Lake Rotorua, and covering 79.8km2. The lake was formed from the crater of a large volcano in the Taupo Volcanic Zone.

Several other lakes of volcanic origin are located nearby, to the east. Directly east of Lake Rotorua is Lake Rotoiti. The two are connected via the Ohau Channel. To the right of Lake Rotoiti is Lake Rotoehu, followed by Lake Rotoma.

To the south, the large Lake Tarawera can be observed. It is the largest of a series of lakes which surround the volcano Mount Tarawera. Like the mountain, it lies within the Okataina caldera. The lake’s surface area is 39 km².

In the middle is Lake Okataina, the northernmost and largest of four smaller lakes lying between Lake Rotorua and Lake Tarawera. The others are Lake Rotokakahi (Green Lake), Lake Tikitapu (Blue Lake), and Lake Okareka. All lie within the Okataina caldera, along its western edge.

New Zealand - August 16th, 2009

Several lakes can be seen in this orthorectified image of New Zealand’s North Island. Easily distinguished by its bright grey appearance here is Lake Taupo, the country’s largest lake by surface area. The city of Taupo can be seen on its northeastern shores. A large agricultural area extends east-northeast of the lake, above the Kaweka Range.

In the upper right quadrant of the image is an area with several lakes, all of which appear dark grey here. Lake Rotorua is the second largest lake in the North Island of New Zealand by surface area, and covers 79.8km2. With a mean depth of only 10 metres it is considerably smaller than nearby Lake Tarawera in terms of volume of water.

The city of Rotorua is situated on its southern shore. In the middle of the lake is Mokoia Island, a rhyolite lava dome with an area of 1.35 square kilometres, rising to 180 metres above the lake surface.

The lake was formed from the crater of a large volcano in the Taupo Volcanic Zone. Its last major eruption was about 240,000 years ago. After the eruption, the magma chamber underneath the volcano collapsed. The circular depression left behind is the Rotorua Caldera, which is the site of the lake. Several other lakes of volcanic origin are located nearby to the east, around the base of the active volcano Mount Tarawera.

The North Island is one of the two main islands of New Zealand.

The island is 113,729 square km in area, making it the world’s 14th-largest island, with a population of 3,250,700 (June 2008 estimate). Approximately 76% of New Zealand’s population lives on the North Island.

The snow-capped peak is Mount Ruapehu, an active stratovolcano at the southern end of the Taupo Volcanic Zone.

Two lakes are visible north of the volcano: Lake Taupo (middle) and Lake Rotorua (top). The latter lies in the Rotorua Caldera, one of several large volcanoes located in the Taupo Volcanic Zone.

Its last major eruption was about 240,000 years ago, after which the magma chamber underneath the volcano collapsed. The circular depression left behind is the current caldera, about 22 km (14 miles) in diameter and now occupied by Lake Rotorua. Mokoia Island, close to the centre of the lake, is a rhyolite dome.
