The steam and super-heated gases which have been pouring from the side of Mt Tongariro since its two surprise eruptions last year are set to be a feature of the volcano for years.

And nearly two months since Mt Tongariro last blew, GNS volcanologists say there’s every chance of another sudden eruption, just as at neighbouring Mt Ruapehu and White Island to the north.

Volcano watch

White Island
This week downgraded from alert level two to one (out of five). A recently-established lava dome has stopped growing, but scientists say a column of magma not far beneath still poses a threat.

Mt Ruapehu
Remains at alert level one with an exclusion zone around the summit. A suspected blockage below the crater lake may be causing a gas build up that could result in sudden eruption.

Mt Tongariro
Remains at alert level one with part of the Tongariro Alpine Crossing closed. Emitting large amounts of gas and sulphur dioxide and scientists still expect a repeat of the last eruption in November.
