March 7th, 2013 Category: Lakes, Volcanoes

New Zealand – March 6th, 2013

Visible in the center of this image is Lake Taupo, a lake situated in the North Island of New Zealand. Lake Taupo lies in a caldera created by a supervolcanic eruption which occurred approximately 26,500 years ago. With a surface area of 616 square kilometres (238 sq mi), it is the largest lake by surface area in New Zealand.

Two stratovolcanoes can also be observed: Mount Ruapehu, 40 kilometers southwest of Lake Taupo, and Mount Taranaki, on a peninsula in the lower left quadrant. Mount Ruapehu is one of the world’s most active volcanoes and the largest active volcano in New Zealand, as well as the highest point in the North Island. Mount Taranaki, or Mount Egmont, is an active but quiescent stratovolcano.

Democratic Republic of the Congo and Rwanda - January 9th, 2012

This wide-swath ASAR image shows volcanic features around Lake Kivu, one of the African Great Lakes. It lies on the border between the Democratic Republic of the Congo and Rwanda, and is in the Albertine Rift, the western branch of the East African Rift.

Visible as a bright white area on the northern shores of the lake, are the cities of Goma, in the Democratic Republic of the Congo, and Gisenyi, in Rwandu. Goma lies only 18 km due south of the crater of the active Nyiragongo Volcano.

Mount Nyiragongo is a stratovolcano in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo. The main crater is about two km wide and usually contains a lava lake.

Italy - March 29th, 2012

Snow rests atop the peaks of the Alps, arching across northern Italy and its border with Switzerland, Germany and Austria. South of the mountains lies the valley of the River Po, home to important cities such as Milan (visible as a grey area in the full image), west of Lake Garda. Although the Apennines, the mountain chain that forms the backbone of the peninsula, are snow-free, some snow can be seen at the summit of Mount Etna, in Sicily.
