Large quake probability continues to drop

[link to www.stuff.co.nz]

The probability of a large aftershock somewhere in the central Canterbury earthquake zone continues to drop as a result of lower seismic activity in recent months.

In GNS Science's updated calculations released today, the probability of a magnitude 5.0 to 5.4 shake in the next 12 months is 69 per cent, compared with 82 per cent in January.

Over the same period there is a 29 per cent chance of a magnitude 5.5 to 5.9 quake in the aftershock zone, which runs from the foothills in the west to Pegasus Bay in the east and from Rangiora in the north to Tai Tapu in the south.
That has fallen from a 39 per cent probability in January.

The chance of a magnitude 6.0 to 6.4 aftershock is now 9 per cent, down from 13 per cent in January, while there is only a 2 per cent probability of a magnitude 6.5 to 6.9 event in the next year, down from 4 per cent at the start of the year.

GNS Science says the probability of a magnitude 7 or higher quake in the next year remains unchanged at 1 per cent.
 Quoting: Tauranga


This is a perfect example of meaningless bullshit. They 'calculate' the possibility of new quakes by the prevalence of the past ones - as if that's the only guide they need.

If it worked that way then the original big ones that hit ChCh shouldn't have occurred - but they did.

Meaningless rubbish.

Panic on Mt Tongariro, as New Zealand volcano erupts again

[link to theextinctionprotocol.wordpress.com]

November 21, 2012 – NEW ZEALAND – A teacher who was on Mt Tongariro with a group of 90 students has captured the ‘‘absolutely spectacular’’ eruption of the volcano on video. GNS Science confirmed the eruption, at the Te Maari crater, happened shortly after 1.20pm. It is the second eruption on the mountain this year; an eruption on August 6 was the first on Tongariro for more than 100 years. Tamatea Intermediate teacher Lomi Schaumkel said they were near the Katetahi hot springs when eruption began. “We were right up there next to it. It was just amazing. It was pretty scary from where we were and it just looked absolutely spectacular, the ash that came out. It really did look like one of those atom bomb explosions, and it made a rumbling sound.’’ There were 90 students, six parents and four teachers in the group. ‘‘Some panicked, some didn’t. Everyone came down safely and it was great.” The group was about 1 km away from the eruption, Schaumkel said. “We saw all these tourists running away from it. We didn’t stick around long.” A further 20 Year 8 pupils from Gulf Harbour School in Whangaparoa were making their way off the track with parents and guides after being just 750m from where the crater erupted. Two bus drivers from Nimon and Sons, who took the Napier children to the mountain, had reported back to their base that they could see an ash plume 2km high, a spokesman said. Department of Conservation (DOC) area manager Jonathan Maxwell said 30 to 50 people were being evacuated from the Tongariro Crossing track. No injuries had been reported but the crossing had been closed. Today’s eruption lasted for about five minutes. GNS has updated the alert on Tongariro to level 2, meaning there is “minor eruptive activity.” The aviation color code has been lifted to red, meaning there is “significant emission of ash” into the atmosphere. In this case, the rebel advance has disrupted all the humanitarian work that has been underway as aid workers have been forced to flee. Autesserre said there were also reports of looting by the Congolese government forces as they evacuated Goma, which may in part explain why thousands of people welcomed the rebel troops. –Stuff

Mount Tongariro erupts again with black plume of ash

Mt. Tongariro, New Zealand, erupted today, November 21, 2012 around 1:20 pm local time and lasted for five minutes. Reports say black plume of ash was sent several kilometers up in the sky. Hikers, including schoolchildren were evacuated. Residents in the Waikato, Hawke’s Bay, Gisborne and Bay of Plenty areas are advised to stay indoor. Spot of eruption was Te Maari Crater on mountain’s western side. GNS Science duty volcanologist Nico Fournier said,

“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.”

As per Geonet, volcanic alert level has been raised to 2 and aviation alert code changed to Orange. Previous eruption was in August this year at upper Te Maari crater(s) on northern side of the volcano.

A brief of history of volcano by Global volcanism program:

Tongariro is a large andesitic volcanic massif, located immediately NE of Ruapehu volcano, that is composed of more than a dozen composite cones constructed over a period of 275,000 years. Vents along a NE-trending zone extending from Saddle Cone (below Ruapehu volcano) to Te Mari crater (including vents at the present-day location of Ngauruhoe) were active during a several hundred year long period around 10,000 years ago, producing the largest known eruptions at the Tongariro complex during the Holocene.

New brief eruption from Tongariro volcano, New Zealand

[link to www.volcanodiscovery.com]

A brief eruption occurred at Te Maari Craters, Tongariro at approximately 13:25 pm local time today (Wednesday, 21 November 2012).
The eruption occurred from the Upper Te Maari crater, in the same area that erupted on 6 August this year. Today’s eruption lasted for less than 5 minutes although local earthquake activity continued for about 15 minutes. The eruption appears to have ceased for now, GeoNet writes.
GNS Science staff Nico Fournier, Agnes Mazot and Craig Miller witnessed the eruption from a few kilometres away. “We didn’t hear anything but could suddenly see an ominous dark grey cloud of ash drifting towards us” said Dr Fournier. The eruption was also seen by trampers walking on the Tongariro Crossing. There are no reports of injury.

Ash erupted during the first few minutes reached 3 km to 4 km height and was clearly seen from Taupo. A light dusting of ash fell across part of State Highway 46 and north-east towards Turangi but no more ash has been reported this afternoon as the gas and steam cloud drifts towards the south east. Ash is being collected this afternoon and will be analysed at Massey University to assess potential human and animal health effects. Results are expected in the next few days. (GeoNet)

Volcanic Alert Bulletin TON-2012/31 - Tongariro Volcano

[link to info.geonet.org.nz]

22 November 2012, 4:15 pm - Eruption update: Tongariro still gassing but no ash; Volcanic Alert Level remains at Level 2; Aviation Colour Code remains Orange
Activity at Tongariro remains low but the volcano is still emitting a significant amount of gas, but with no ash.

Today’s observations confirm that the volcano is producing a lot of gas. The odour was noticed in the Manawatu and Hawke's Bay, the primary downwind areas of Te Maari (Tongariro).

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.

Read about issues related to volcanic gas on the International Volcanic Hazards network.
GNS scientists carried out an observation flight around Tongariro today and were able to assess the general extent of the yesterday’s eruption. GNS scientist Craig Miller reported that “The Upper Te Maari hasn’t changed significantly after the eruption”.

The Volcanic Alert Level remains at 2 and the Aviation Colour Code at Orange.

GNS Science continues to closely monitor the situation.

Background
The Volcanic Alert Level ranges from 0 to 5 and defines the current status at a volcano. Level 2 indicates that a minor eruption has occurred.

Aviation Colour Codes are based on four colours and are intended for quick reference only in the international civil aviation community. Code Orange indicates that a volcanic eruption is underway but with little or no ash being produced.

Large quake probability continues to drop

[link to www.stuff.co.nz]

The probability of a large aftershock somewhere in the central Canterbury earthquake zone continues to drop as a result of lower seismic activity in recent months.

In GNS Science's updated calculations released today, the probability of a magnitude 5.0 to 5.4 shake in the next 12 months is 69 per cent, compared with 82 per cent in January.

Over the same period there is a 29 per cent chance of a magnitude 5.5 to 5.9 quake in the aftershock zone, which runs from the foothills in the west to Pegasus Bay in the east and from Rangiora in the north to Tai Tapu in the south.
That has fallen from a 39 per cent probability in January.

The chance of a magnitude 6.0 to 6.4 aftershock is now 9 per cent, down from 13 per cent in January, while there is only a 2 per cent probability of a magnitude 6.5 to 6.9 event in the next year, down from 4 per cent at the start of the year.

GNS Science says the probability of a magnitude 7 or higher quake in the next year remains unchanged at 1 per cent.
 Quoting: Tauranga


This is a perfect example of meaningless bullshit. They 'calculate' the possibility of new quakes by the prevalence of the past ones - as if that's the only guide they need.

If it worked that way then the original big ones that hit ChCh shouldn't have occurred - but they did.

Meaningless rubbish.

Large quake probability continues to drop

[link to www.stuff.co.nz]

The probability of a large aftershock somewhere in the central Canterbury earthquake zone continues to drop as a result of lower seismic activity in recent months.

In GNS Science's updated calculations released today, the probability of a magnitude 5.0 to 5.4 shake in the next 12 months is 69 per cent, compared with 82 per cent in January.

Over the same period there is a 29 per cent chance of a magnitude 5.5 to 5.9 quake in the aftershock zone, which runs from the foothills in the west to Pegasus Bay in the east and from Rangiora in the north to Tai Tapu in the south.
That has fallen from a 39 per cent probability in January.

The chance of a magnitude 6.0 to 6.4 aftershock is now 9 per cent, down from 13 per cent in January, while there is only a 2 per cent probability of a magnitude 6.5 to 6.9 event in the next year, down from 4 per cent at the start of the year.

GNS Science says the probability of a magnitude 7 or higher quake in the next year remains unchanged at 1 per cent.
 Quoting: Tauranga


This is a perfect example of meaningless bullshit. They 'calculate' the possibility of new quakes by the prevalence of the past ones - as if that's the only guide they need.

If it worked that way then the original big ones that hit ChCh shouldn't have occurred - but they did.

Meaningless rubbish.

Ha! I wrote a first comment to that very article politely inquiring upon thier "scientific" accuracy prior to Sep 4 2010 but the moderator didn't "approve" it. It seems one is allowed to gripe but not make too much sense or get close to the truth of things. Funny that.

lols, AC, that is funny (and quite a concern) isnt it

we seem to understand what is going on volcanically and seismically in nz a lot better than they do, which seems rather weird, doesnt it...

maybe they will start listening to us (and maori people who understand the connectedness of our volcanoes and quakes) one day

thanks for posting, nice to have your input here

Tongariro eruption possible within a week

[link to www.stuff.co.nz]
video and photos

Volcanic activity at Mt Tongariro remains low but the volcano is still emitting a significant amount of gas, GNS Science says.

The volcano erupted yesterday, for the second time this year, and scientists are now keeping watch on both Mt Tongariro and Mt Ruapehu, warning that further eruptions are expected.

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.

Mt Tongariro had lay dormant for more than 100 years until an eruption early on August 6.

Scientists today used an observation flight around the mountain to assess the extent of yesterday’s eruption.

The volcano was producing a lot of gas, but with no ash. The odour was noticed in the Manawatu and Hawke's Bay, the primary downwind areas of Te Maari, GNS Science said.

Depending on weather conditions people may notice the smell of sulphur 100km or more from the volcano. However, any health impact was likely to be limited to minor irritation of the skin and eyes.

Historical evidence shows that there may be more eruptions to come.

"Progressive pressure may build up over time and we think that's what's happening," GNS vulcanologist Nico Fournier said.

"At the moment we can't make any judgement calls but the overall opinion is if there is an eruption it is unlikely to be quite big ... the bigger the eruption the more signals you should get beforehand and we haven't seen that."

Signals included earthquakes, gases emitted and the ground swelling slightly.

"We haven't had any evidence of any of those at the moment," Fournier said.

Scientists only had those historical events to compare the recent activity to, and Fournier said that a series of eruptions in the late 1800s indicated that more eruptions were to follow.

Known eruptions at Tongariro occurred in 1869 and intermittently in the years between 1886 and 1897.

Also, research based on volcanic events around the world showed that eruptions usually came in a series, Scott said.

"When you get an eruption it can stop, but most of the time there's further eruptions over months or years."

The point of origin of yesterday's eruption was similar to that from August, but two currents were formed, GNS vulcanologists said in a statement.

These currents, called pyroclastic density currents, consisted of a mixture of ash, volcanic gas and atmospheric air.

The two small currents were formed to the west and north of the crater and were believed to have been created because the ash column did not have enough energy to rise, which meant it probably collapsed at the base and the currents flowed downhill.

"There is no evidence at this stage of big blocks having been ejected far from the crater during the eruption."

There was also no evidence of magma reaching the surface.

With Ruapehu also recording activity, there was still an increased likelihood of an eruption there too.

GNS took samples of Ruapehu's Crater Lake yesterday and hoped to have a better insight once results were in next week, Fournier said.

While New Zealand vulcanologists didn't usually have to keep a close eye on two volcanoes experiencing heightened activity at the same time, they weren't letting anything slip, he said.

"We need to make sure we don't miss anything at Ruapehu while Tongariro is putting on a show."

ERUPTION DISRUPTION

The Tongariro Alpine crossing would remain closed until the middle of next week, unless the Department of Conservation was advised otherwise by GNS, programme manager for communication relations, Kim Alexander-Turia, said.

The main huts on the mountain, including Oterere and Mangatopopo were also closed.

The Whakapapa track to Tama Lake remained open but visitors should inform DOC's Ruapehu office when they planned to be on the track, Alexander-Turia said.

Civil Defence has cancelled its national advisory regarding ash fall as no ash is coming from the volcano.

The agency did not have any further advice for people in the area other than what was on their website.

All roads in the area were open but police urged anyone driving nearby to be cautious - not so much of the volcano, but of other cars in the area.

Area Commander Inspector Steve Bullock expected traffic in the area to become heavier over the next few days as many people would want to take advantage of the clear conditions to visit.

"That is completely understandable and whilst we don't discourage people from now travelling to the area we are asking them to put road safety and their own safety before sightseeing."

People were urged to pull over to the side of the road to view the mountain rather than trying to view it while driving.

Some Air New Zealand flights cancelled this morning were expected to resume this afternoon, including flights in and out of Taupo and Gisborne.

Tongariro could erupt again: GNS

[link to www.odt.co.nz]

The immediate threat of eruption at Mt Tongariro has passed but there remains a chance of another sudden eruption within the next two weeks, GNS Science says.

Twenty-four hours after the eruption from the mountain's Te Maari crater, GNS Science has cancelled its national advisory.

However, it says there remains a "significant probability of a sudden eruption within the next week".

Should a further eruption occur, a new national advisory or warning would be issued, GNS Science said.

Signs of volcanic activity settled overnight but experts continue to monitor the mountain for changes.

Thick grey smoke, gas and ash spewed 4km into the sky from Te Maari vent on the western side of the mountain during the unexpected eruption just before 1.30pm yesterday.

It is the same place where Tongariro erupted in August, for the first time in more than a century.

Yesterday's activity prompted an aviation red alert, which has since been dropped to orange.

Ash in the sky above the mountain also dissipated overnight.

Experts planned aerial observation to check how much gas was in the atmosphere and any other changes, said GNS Science duty volcanologist Nico Fournier.

Scientists have predicted that another eruption of similar size could be expected at any time during the next few weeks, though the activity was not expected to escalate.

"At the moment there are no such signs. It doesn't mean as we saw yesterday or in August that an eruption could not happen; it's quite possible," said Dr Fournier.

"It's a sign of concern for any volcanoes when they don't provide us with any warning."

The Department of Conservation has closed the Tongariro track, which was not expected to be reopened for at least three days.

Dr Fournier advised anyone planning to go to mountains in the area to first check with the Department of Conservation for any safety updates.

Groups of school children and trampers were on the mountain to walk the Tongariro Crossing when the volcano burst into activity, sending many into shock and awe.

Conditions on the mountain were today largely back to what they were before the eruption, with the volcano emitting some steam and gas at the same level it was before the August activity, said Dr Fournier.

"If the roads are open it's pretty much deemed safe and everybody's in touch with us."

Yesterday's activity has also affected flights to and from Taupo, Rotorua or Gisborne airports.

Ten Air New Zealand flights scheduled this morning were cancelled, also causing disruptions at some other regional airports.

The airline would continue to assess the situation, a spokeswoman said.

Air New Zealand flights to Rotorua are running again as the ash cloud to the east of the country from Mt Tongariro's eruption yesterday clears.

Flights to Taupo and Gisborne continue to be affected by delays and cancellations, but normal services are expected to resume as the day progresses, said an airline statement.

The airline is working with Civil Aviation Authority, the MetService and other authorities to monitor the situation and make adjustments to routes to ensure aircraft remain clear of any ash.

Passengers are advised to check the Air New Zealand website www.airnewzealand.co.nz for flight arrivals and departures information which will be constantly updated throughout the day.

Ten Air New Zealand flights scheduled this morning were cancelled, also causing disruptions at some other regional airports.

The airline will continue to assess the situation as the morning progresses, said a spokeswoman.

Passengers were advised to check the airline's website for flight details.

SHOCK AND AWE AS VOLCANO BLOWS

As Mt Tongariro started rumbling, children and trampers on the mountain turned to run, fearing the worst.

Not a second later, a thick grey plume of smoke erupted from the Te Maari vent and those closest looked at each other to see what the other was doing.

In one of the school groups on the mountain to walk the Tongariro Crossing, some children cried while others reached for their cameras.

The five-minute eruption sent ash 4km high into the sky without warning and was followed by 15 minutes of volcanic activity, but it was smaller than the August event.

But scientists have predicted that another eruption of similar size could be expected at any time during the next few weeks, though the activity was not expected to escalate.

Paul Cowan, a teacher from Auckland on holiday, was about 1km to 1.5km away from the 1.25pm eruption. He said there was nowhere to run because smoke was coming out of vents all around them.

"It was fantastic but it was actually a bit scary and everyone started running," he said.

Lynn Donovan, a tourist from Ireland, said that after they heard the rumble they turned around and "all of a sudden" a great tower of thick smoke poured from a crater.

"It was a little nerve-racking and some people started running but a guide from another group calmed us all down and told us what was going on," she said.

During the last eruption, the mountain spewed rocks into the air so they were told to be careful, but otherwise they were safe and there was no need to panic.

Principal John Petrie of Gulf Harbour School, which was doing the crossing with a group of 20 Year 8 students and 10 adults, said they didn't hear anything but some of the children started to notice the billowing cloud of rising ash.

"Initially the kids started getting their cameras out and were quite wowed by it, but as it continued to rise it got quite high and then the apprehension started creeping into all of us," Mr Petrie said. "Some of the kids started crying but others were quite captivated by it."

Last night, continued minor eruptive activity meant Mt Tongariro's Volcanic Alert Level remained at 2.

GNS duty volcanologist Nico Fournier said a northeast wind dragged the ash cloud over Lake Taupo. A light dusting of ash yesterday fell across part of State Highway 46 and towards Turangi.

"We're talking a matter of hours not days for it to fall," Dr Fournier said.

Meanwhile, tourism operators were excited about the eruption.

Adrift NZ tour guide Stewart Barclay, who chairs a group of 30 users of Mt Tongariro, said some school groups had cancelled tours but in the long run the eruption would be "fantastic for business".

He said they had been busier this November than the last because of the eruption in August.

"People just love being near it, they come to gawk at a truly active volcano ..."

Great Lake Taupo spokeswoman, Leola Abraham, said they were trying to focus on the positive impact of the eruption - that it put the region in the international public eye.

And the 8500 people taking part in the Contact Lake Taupo Cycle Challenge this weekend shouldn't change their plans - it will still go ahead.

Event director Kay Brake said they were monitoring the situation closely and there were contingency plans in place.

Tongariro erupts - where will the ash cloud go?

[link to www.nzherald.co.nz]
video

WeatherWatch's Philip Duncan on where the ash is likely to fall.
GeoNet has confirmed that Mt Tongariro has again erupted this afternoon, sending an ash plume several hundred feet into the sky according to media reports.

WeatherWatch.co.nz has been checking the wind flows and wind speeds in the area.

Our feeling is that much of the ash will fall locally, due to only light winds in the region and therefore the ash will fall to the ground sooner.

However lighter ash can travel great distances at higher altitudes - and this can impact flight routes and airports.

The wind flow on the mountain and surrounding mountains/weather stations currently shows a light south westerly at ground level. Wind flows higher up are expected to be light also but generally pushing the ash in an easterly direction.

The plume may drift anywhere within the eastern quarter - anywhere from Taupo to Hawkes Bay at this early stage.



The forecast for the next five days shows light winds from the west, similar to today.

The good news, as like the last time Tongariro erupted, is that the wind flow is pushing any ash clouds away from the main North Island/South Island air route - which is to the west of the mountain (and the ash is being carried eastwards).
However it does mean ash will fall over State Highway 1, the Desert Road.

Strong smelling gases may travel much further, as it did last time. Those who are concerned are advised to check the GeoNet or GNS Science websites for full details.

Farmers and those who rely on rain water and are near the mountain - or in the potential path of ash - should disconnect rain water tanks immediately.

Motorists are reminded that while ash may seem fluffy, if it is in fact small and harsh rock particles - which scratches windscreens and can choke engines if thick enough.

Mount Tongariro erupts: Sightseers warned off

[link to www.nzherald.co.nz]

For more on what to do during an ash fall, see here.

Civil Defence said ash could be a health hazard, especially for people suffering breathing difficulties.

People affected by ashfall should wear a dust mask cover their nose and mouth and protect their eyes.

A woman who lives near the mountain said sulphur-smelling ash had been raining down on her home.

Robyn Bennett, who lives 6km from the mountain, said she could see the plume of ash rising into the sky.

"It's sitting under some cloud and that's why it's pushing down onto us," she said.

"It smells worse than rotten eggs."

Ms Bennett didn't think she and her husband would need to leave their home, "not unless she starts spewing out a whole lot of red rocks", but they were waiting to hear from Civil Defence or DoC.

James Perry, who works at the Lake Taupo Hole in One attraction on the resort town's lakefront, had a clear view of the mountains of the central plateau and saw the ash as soon as the eruption occurred.

"It basically went straight up and did the mushroom cloud and then the wind's just spread it from there," he said.

Hole in One owner Tiffany Battell said the smell of sulphur was obvious yesterday and she had wondered then whether it was a precursor to another eruption.

Rhys Harnett of Auckland had stopped on the lakefront to eat his lunch at about 1.30pm when he saw black smoke rising silently from the crater of Mt Tongariro, which he said plumed out above the clouds. He took a photo on his cellphone and rang his home in Auckland to relate what he had seen.

"I had a feeling it was not an eruption but letting off steam."

WeatherWatch head weather analyst Philip Duncan said with only light winds in the region, much of the ash was expected to fall locally.

Lighter ash could travel greater distances and the plume may drift anywhere anywhere from Taupo to Hawkes Bay.

Ash was expected to fall on the Desert Road but was likely to be pushed away from the main air route, to the west of the mountain.

Tongariro, in the centre of the North Island, erupted in August for the first time in 115 years, sending ash as far east as Napier.

According to GeoNet, Tongariro is a complex of multiple volcanic cones constructed over a period of 275,000 years.

The mountain's active vents include Te Maari, Emerald, North Crater and Red Crater.
