Tongariro National Park is the oldest national park in New Zealand, located in the central North Island. This national park has three active volcanoes, located at the south end; Tongariro, Ngauruhoe and Ruapehu. The third mountain last erupted in August 2012 ago.
Tongariro National Park also has two other active volcanoes in the far north, which last erupted more than 20,000 years ago. As reported by Amusingplanet, Ruapehu itself is one of the most active volcanoes in the world and also the largest active volcano in New Zealand.
Experiencing minor eruptions almost every year, Ruapehu began erupting at least 250,000 years ago. The biggest eruptions occurred on the mountain successfully delivered a beautiful crater lake. Lake bright color caused by dissolved minerals in the water that comes from the surrounding rocks. Do not be surprised if these mountains now have an exotic style.
Not far from Rupehu, there is Mount Tongariro consisting of at least 12 volcanic cones. Geologically, Ngauruhoe is even part of the volcanic cone of Mount Tongariro. The mountain is also regarded as the most active and has erupted more than 70 times since 1839. There are many craters that formed around the mountain is a result of the massive explosion. Some of them have been filled with water, called the Blue Lake and the Emerald Lakes.
