Volcanic Eruption in New Zealand
Poor little New Zealand is coping it again, this time with a volcanic eruption - Mt Tongariro.
I copied this article from the NZ Herald:
- Mt Tongariro erupted at 11.50pm last night, hurling rocks up to 1km.
- Ash cloud drifting to the east of Tongariro, landing as far as Napier city
- SH1 and SH46 have reopened. Flights to and from Napier cancelled, while other North Island services have been delayed.
- GNS: It was a hydrothermal-driven eruption, rather the magmatic
- It was the first eruption in more than a century
- Turoa and Whakapapa skifields remain open
Volcanic activity on Mt Tongariro could continue for "weeks, months or even years", a volcanologist says.
Rocks and ash were thrown up to a kilometre from the central North Island, which last night erupted for the first time in more than a century.
The eruption forced the closure of roads and disrupted flights, while nearby residents were advised to stay indoors.
Ash has reached as far as the Napier CBD, as the ash plume drifted to the east of the mountains over the course of the morning.
The volcanic alert level for Mt Tongariro has risen from 1 to 2, while the aviation colour code has been raised to red.
Brent Crowe of the Bay of Plenty police told the press conference that ash and rock was ejected from the volcano in a 1km radius.
The police focus remained on public safety, he said.
Three Department of Conservation huts on Mt Tongariro are being cleared.
All locals residents were urged to remain calm and check water supplies to make sure they were not contaminated.
The eruption was reported to police just before midnight by a member of the public who reported seeing explosions on the northern face of the mountain.
The witness told police the eruption had created "a new hole in the side of the mountain".
Police had received no reports of injury or damage, but the Ministry of Civil Defence & Emergency Management advised people in affected areas to stay indoors.
There have been no mandatory evacuations ordered by authorities, but some residents have chosen to leave the area.
A "potential threat to New Zealand advisory" is in place for Waikato, Hawkes Bay, Gisborne, Manawatu-Wanganui, Bay of Plenty and Taranaki.
Local resident David Bennett said this eruption was "just about as spectacular" as Ruapehu's eruption in 1995. Mr Bennett lives about 6km away from the eruption on the southern shores of Lake Rotoaira
HYDROTHERMAL ERUPTION
GNS Science volcanologist Brad Scott told reporters it had not detected any increased activity in the 12-14 hours before the eruption.
"There has been no escalation coming into the eruption and we've seen no escalation post the eruption," Mr Scott said. "The eruption gave us no warning ... it just crept up on us."
A flyover of the mountain this morning revealed a steam plume coming from the mountain but there was no indication of volcanic ash this morning.
Scientists were unable to see the immediate impact of the eruption on the mountain because of bad weather and low cloud.
"We were unable to see the impact immediately around the craters so we still can't confirm just which crater the eruptions occurred from,'' he said.
"We've had a small-scale volcanic eruption. It appears to be driven in the hydrothermal rather than the magmatic process, there's been an ash plume, there's been ash-fall down wind.''
Mr Scott said the eruptions are expected to continue for "at least days".
Auckland University volcanologist Phil Shane said the small eruption this morning could signal the start of a pattern of explosions at the central North Island mountain.
He drew a comparison to the Caribbean volcano Montserrat, which rumbled to life in 1995 and has continued to erupt until today.
A more violent eruption in the coming days or a drop off in all volcanic activity was also possible, Associate Professor Shane said.
"We don't know how long it could go. It could be a one off or it could go weeks, months years or even a decade."
ROADS
Police closed State Highway 1 and State Highway 46 as a precautionary matter overnight but they have since reopened.
New Zealand Herald reporter Jamie Morton said the ash this morning on SH46 at Lake Rotoaira, just north of Tongariro is a "thick, clay-like mud", about half a centimetre thick.
"It's just carpeted everything, all the fields, cars, trees - the whole landscape looks quite murky and grey," he said.
"Roofs in this area, they're all absolutely coated in this ash."
Contractors are currently sweeping the ash from State Highway 46, Mr Morton said.
"There is also quite a noticeable smell ... quite a murky smell. We've had reports in Waiouru that there is a sulphur-like smell in the area. That is not the case here."
Truck driver Bryn Rodda was one of the first to see the eruption.
"As I was coming up from Waiouru .... I saw this beautiful, big cloud and I thought 'gee that looks like a volcanic plume'. Just as I thought that there was a great big orange flash," he told National Radio.
He said he saw a thick cloud of ash develop and fine grey ash started falling.
"(The cloud) looked like a fist, basically, at an angle across the sky. About the wrist section of the fist there was an orange ball of flash I could see.
"It was quite impressive."
AVIATION
Air New Zealand has announced all flights in and out of Hawke's Bay airport are cancelled today due to the ash cloud from the Mt Tongariro eruption.
Further regional flights to and from destinations east of Tongariro could be delayed or cancelled and passengers should check its website for updates.
Captain David Morgan, Air New Zealand general manager airline operations and safety and chief pilot, said the airline is working with the relevant authorities to make adjustments to flight routes to ensure aircraft remain clear of any ash.
"We will not fly through ash and are constantly taking guidance from the CAA and the MetService to ensure we can continue to carry passengers where safe routes and altitudes are available."
Civil Aviation Authority manager of meteorology Peter Lechner said that ash can build up in the turbines of aeroplanes and helicopters, causing engines to stall.
"It can result in significant flight risk."
FARMING
Federated Farmers said initial reports indicated the eruption had had little impact on farm pasture or stock drinking water.
Four farms had been contacted in different parts of Hawkes Bay, including one on the Taupo-Napier highway, and they were yet to report any ash.
"While we are waiting on reports from our Ruapehu province, GNS predicted ashfall indicates it will largely fall on National Park or forested areas," the group said in a statement.
SKIFIELDS
Skifields on Mount Ruapehu were open this morning, with operators saying the eruption of Mt Tongariro posed no threat to the Whakapapa and Turoa ski areas.
The volcanic vents on Tongariro, Ngauruhoe, and Ruapehu were independent of each other and there was no reason or indication of volcanic activity on Ruapehu, a Mt Ruapehu spokesman said.
"The Te Maari crater where the eruption occurred is at least 20km away from the ski area."
The ash was blowing to the east, away from the skifields.
EARTHQUAKES AND ERUPTION
A joint agency incident management centre has been established at the Whakapapa Department of Conservation Visitor Centre.
GNS volcanologist Brad Scott told Radio New Zealand the eruption began from the Te Maari craters at the north end of Mt Tongariro at 11.50pm yesterday.
An earthquake lasting about five minutes accompanied the eruption and residents reportedly heard the explosions.
"When they went outside to have a look they saw the volcano starting to erupt. They saw incandescent blocks - glowing hot blocks - and they saw an eruption column being developed and within about five minutes they were experiencing a light local ash fall."
GNS had been aware of some issues at Mt Tongariro for a few weeks, "but to be honest we didn't see anything in the latest data up until last night that indicated it was ready to erupt", Mr Scott said.
He said there was likely to be further activity.
"There's not showing any escalation - the earthquake activity hasn't increased or anything like that - but we would probably anticipate some more activity now that the craters have broken through."
Mt Tongariro last erupted between 1896 and 1897.
WEATHER AND AREAS AFFECTED
Weatherwatch said where the ash would go depended on the wind.
"We've updated our wind predictions - made more difficult by the fact a large low from the Tasman Sea is expected to cross over Central Plateau. The winds around the centre of the low are very light - which is good news for any further potential ash clouds, as it would decrease the chances of significant drift," the forecaster said in an update.

Mt Tongariro eruption: Where will the ash go?
---
Civil defence spokesman Vince Cholewa told NewstalkZB ash could reach those living in Waikato, Hawkes Bay, Gisborne, Manawatu-Wanganui, Bay of Plenty and Taranaki.
"The advice to people is to stay indoors, because volcanic ash can obviously be a health hazard, if they're indoors please close windows and doors to try and limit the entry of ash."
Mr Cholewa said not all areas alerted were affected by ash but that situation could change.
"We're working actively with GNS Science who operate the monitoring equipment on the mountains, and with police so all the information from the ground is being gathered, and decisions will be based on that information.
"Evacuations have not been ordered, please listen to the radio for advice from local authorities and police, any evacuations would be issued at that level, and based on the evidence from GNS Science."
Police say the wider community's health is not currently at risk from the eruption of Mt Tongariro.
There was no need for the wider community to remain indoors with closed doors and windows.
"At this time the only risk is minimal and would only be to people in the local vicinity of the eruption who have a predisposition to respiratory issues.
"The only other advice is in relation to water supplies of the rural community in the immediate local area," police said in a statement.
WHITE ISLAND
New Zealand's other high profile active volcano, White Island, also had its alert level raised from 1 to 2 on Monday after a small eruption was recorded in its crater lake.
GNS Science said the increased activity on White Island is not related to the Tongariro eruption.
Poor little New Zealand is coping it again, this time with a volcanic eruption - Mt Tongariro.

Re: Volcanic Eruption in New Zealand
Yikes, too right!
For such a small country it certainly has it's share of living volcanoes!
I remember learning in school about the eruption of Mt Tarawera in 1886, which destroyed the famous pink and white terraces (the 8th wonder of the world). The explosions were apparently heard as far away as Auckland to the North and Christchurch to the South!

Re: Kamchatka's volcanoes activity
Thank you, s-kur. Btw, do you have any place where you and others can go in case of an emergency? Are there any official evacuation plans, or maybe you have relatives or friends that you can go to if one of those volcanoes will suddenly erupt? It seems like there are several close to your location, so thinking about this probably would be wise.

Re: Kamchatka's volcanoes activity
Yes, thanks s-kur. What do the local specialists predict? You say that the level is lower now, hopefully it will not intensify again. I read that the seismological activity also increased in the area, so it's not only volcanoes?

Re: Kamchatka's volcanoes activity
I don't aware about such a places and have not seen an evacuation plan...I think it doesn't exist :) Anyway, without jokes, you're right and I have to find it out. Ministry of Emergency Situations of Kamchatka only warn and explain safety measures in case of eruption with "ash precipitations". The only places I might go is my native island Paramushir, but since its transport connection is bad (helicopters and ships) it might difficult to go there ..in case of an emergency. As local says "Life on gunpowder keg" :)
Local scientists say nothing exciting. Yes, volcanoes just slightly smoking, but it might become worse at any moment. Regarding seismological activity here an actual information
The last earthquake 5.7M I have felt as strong occured in october

A little info from wikipedia
It reminded us of its never ending presence today, with an explosion and ash plume of 3 km, 4 hours later another one of 1.2 km.
_http://www.eluniversal.com.mx/estados/2015/aumentan-vigilancia-por-volcan-de-colima-1065956.html (spanish)
Authorities urge population to be calm since it was just ash, with its recomendation about what to do and deal with ash, since there are many little towns around, municipality civil portection has increased their rounds to towns giving recomendations. (Cover mouth and nose with a mask or rag, clean nose and throat with water, use frame glasses instead of lens, close windows and remain inside, cover animals food and water deposits)
