At 1.25pm on 21 November 2012 Mt Tongariro let fly with a two kilometre plume of ash emanating from Te Maari Crater. This is the area that erupted on 6 August. The eruption only lasted five minutes but GNS are monitoring the situation. The volcano alert for Tongariro has been lifted to Level 2, which means ‘minor eruptive activity.’ The Aviation Colour Code is changed to red. Flights between Wellington and Taupo are cancelled.
A lot of snow has disappeared off the mountain and we now have many people circumnavigating the mountain as well as walking the Tongariro Alpine Crossing. There were several school groups on the mountain, some within one kilometre of the eruption. No injuries are reported.
