Mt Tongariro erupted today just before 1.30pm, its second bout of volanic activity this year. Here is a wrap-up of the mountain's history.
August 6, 2012: The volcano erupts for the first time in more than 100 years. It was a gas-driven eruption and created new vents
November 1896: Until October 1897: an eruption occurred from Upper Te Maari Crater, depositing ash in Napier.
January 1893: Gas emissions were reported, along with two explosions, the second of which ejected pumice.
November 1892: Te Maari again belched forth an immense quantity of steam, mud and boulders; the ejected material rose 2,000 - 3,000 feet (600 - 900 m) before rushing down the mountain side.
June 1886: An ash eruption occurred from the Upper Te Maari Crater.
1869: A large eruption (accompanied by an earthquake) formed the upper Te Maari Crater during an explosive eruption. Māori descriptions include a "bright red flame through the smoke that would burst and fall like snow".
