The eruption at Tongariro's Te Maari crater about 1.30pm was thought to have sent a two-kilometre plume into the air but GNS Science confirmed today that the ejection was three or four kilometres high and lasted for about five minutes.
Yesterday?s eruption occurred without any measured precursory changes and this reinforces the unpredictable nature of volcanoes. We cannot say what will happen next at Tongariro but the scenario considered most likely, based on the August 2012 eruption and the description of late 1890s eruptions, is that we could expect another eruption of similar size at any time during the next few weeks. Eruptions are not expected to escalate in size. http://info.geonet.org.nz/pages/viewpage.action?pageId=3801188
Mt Tongariro could keep erupting for up to nine months, GNS volcanologist Brad Scott says.
The August eruption was a "vent-clearing blast and naturally more explosive", he says.
Now that there is an open vent, it is easier for eruptions to occur.

Depending on weather conditions people may notice the smell of sulphur a hundred kilometres or more from the volcano. However, any health impact is likely to be limited to minor irritation of the skin and eyes, and possibly some irritation of the throat. Anyone who has respiratory problems and/or uses asthma medication, and has concerns with their health related to the gases, should seek medical advice.

A 3km exclusion zone has been set up around Mt Tongariro after it blew rock and ash high into the air yesterday, with experts warning there is a very real chance of it erupting again
