Mt Tongariro - NZ - Erupts

Hi all,

Mt Tongariro in New Zealands North Island has unexpectedly erupted today -

The eruption came from Te Maari Crater, on the western side of the mountain, shortly before 1.30pm

A massive plume of ash can be seen coming from the mountain.

GNS Science duty volcanologist Nico Fournier told APNZ the eruption happened about 1.20pm.

"There was one eruption, essentially one explosion, and it was not sustained. It spewed some ash possibly a couple of kilometres up the air. The ash is now drifting to the east-southeast.''

Dr Fournier said the eruption was not very loud and was smaller than an earlier eruption in August.

Dr Fournier was a few kilometres away when the eruption happened and said while he was safe, he had "a good view of the explosion''.

"It was remarkable a few minutes ago, now it's dying off,'' he said about 20 minutes after the explosion.

GNS Science has increased the aviation colour code from yellow to red following the eruption. The red status means an eruption "is forecast to be imminent with significant emission of ash into the atmosphere likely

It's interesting that only earlier this week GNS scientists warned New Zealanders that it would be Mt Ruapehu erupting within weeks as see here in my other thread -

Maybe this is the start of a very active period of Volcanism for NZ? Hopefully it will not lead to an eruption of one of the Worlds biggest Calderas - Taupo

Dun dun dunnnnn. Wonder if we'll see activity increase along the Ring of Fire and have eruptions at Fuji (given pressure increase) and Ruapehu (given it's right there) and maybe others all over the show and there goes Xmas flights just like last year's Finnish volcano.

Natural change is afoot, wars rage on, people killing, people dying but nope Twinkies are more important.

The biggest worry is Lake Taupo which is in the same Volcanic Chain as Tongariro and Ruapehu. It's one of the worlds largest calderas at over 35km wide.

The initial event 26,500 years ago is the largest eruption and is known as the Oruanui eruption. It ejected an estimated 1170 cubic kilometres of material and caused several hundred square kilometres of surrounding land to collapse and form the caldera. The caldera later filled with water, eventually overflowing to cause a huge outwash flood.[3] It is possible that the Lake Taupo event contributed to starting the Last Glacial Maximum

Bigger picture
Last eruption was 115 years ago

Some more information from NZ News -


Civil Defence was warning people to stay indoors if ash was present.

"Light volcanic ash fall can be anticipated downwind of Tongariro and may impact the following areas or regions: Waikato; Hawke's Bay; Gisborne and Bay of Plenty.

"Volcanic ash could be a health hazard, especially if you suffer from breathing difficulty. If outside, seek shelter (e.g. in a car or building)."

It was advising people to close all windows and cover their mouths if caught in the ash. People should stay out of designated restricted zones.

Lake Rotoaira resident Robyn Bennett said there was a big, black ash cloud over her house, which was about a kilometre from the eruption site.

"It's just blew her stack," she said.

She said the air smelled of sulphur.

I wonder if all this is related to all the 4.5 or greater EQ's I've been watching over the last few days?

never seen so many at this mag... within the NEIC 7day, especially with the low average of just 192 total for this period.

We've been expecting this for a few weeks now, but was surprising it was Tongariro rather than Ruapehu. Didnt feel anything around the time it popped which is odd given we felt a small earthquake a few weeks back that hit around the Taupo region, first one ive ever felt personally.

Couldnt see any plume from where we live this afternoon since its been real hazy (although that in of itself could be the cause of the haze), we normally can see Ruapehu peaking out over the top of the horizon on a clear morning and Tongariro isnt all that far from there, so ill see if I cant see it tomorrow.

No one got hurt (although it scared some School Kids on a trip there it seems
), pitty it was'nt a bigger one
but this'll calm the regions activity down a good deal which is a good thing since they where getting worried.

Supposedly we'll get some ash fall in the Waikato region... and given ive had allergies this spring... great

Seems this is was a new vent that opened up, shows that the volcanoes in that region are all linked down bellow, be interesting if Ruapehu also went up like they where expecting... hopefully not and heres hoping its not too big a pressure since our town sits next two small volcanoes as well and we arent geographically speaking all that far from the Tongariro National Park region.

Stay safe BigfootNZ and all of you down there.

One expected to blow but another saying hello isn't something we want to see, especially not there.

I would have said that was only a worry if there was a dome building in the caldera. Don't know if there is or not.
