Two NZ Volcanoes Show Signs of Unrest

Mt Ruapehu

A volcanic earthquake swarm has been reported at Mt Ruapehu. The seismicity began on April 26. The Crater Lake temperature, which has been rising since October 2015,  has now reached 40°C (from 25°C in mid-April). Mt Ruapehu remains at Volcanic Alert Level 1 (Minor volcanic unrest), Geonet reported.

White Island

A minor eruption occurred at White Island (Whaakari) at about 11:00 pm on Wednesday, 27 April 2016. Moderately elevated seismic activity is occurring, said Geonet. Additionally:

  • Water level in the Crater Lake has fallen by 2m in the last 2 weeks.
  • Lake temperature has increased by 2°C, to 58°C, since February.
  • SO2 output ranging from 90 to 480 tons per day reported over the last 5 weeks, but said to be typical values for White Island.

“A dark-green ash deposit from the eruption covers at least 80% of the floor of Main Crater, and up the sides of the crater wall on both the north and south sides. At a distance of 500 m from the eruption site the ash deposit is about 5 mm thick. The green colour is due to minerals on the ash.”

Alert Level was initially raised to Level 3 (Minor Volcanic Eruption) and the Aviation Color Code to Orange. The Alert Level was lowered to 2 from 3 on Thursday.

Cyclone PAM: “Entire communities have been blown away”

Posted by feww on March 15, 2015

Links sent by Tom C.

Super Cyclone PAM probably caused “one of the worst disasters ever seen in the Pacific”

Up to 90 per cent of homes in Vanuatu’s capital Port Villa has reportedly  been seriously damaged by Super Cyclone PAM, leaving “most” of the population homeless, with no information available yet as to the fate of more than 33,000 people who live on the extremely vulnerable outer islands. 

“This is likely to be one of the worst disasters ever seen in the Pacific,” said Oxfam Country Director in Port Vila, Colin Collet van Rooyen.

“Entire communities have been blown away.”

Cyclone PAM made a direct hit on Vanuatu island late Friday, plowing through the archipelago of 65 islands [pop. ~ 270,000] with supercharged force.

“With more than 250,000 people at risk from the severe tropical cyclone there is real concern of a potentially high death toll and of enormous destruction, particularly given the traditional housing that is so prevalent through the islands,” said the report.

“Cyclone Pam has destroyed all but one of mobile towers in Port Vila so no comms between Efate and both nth and sth provinces,” said a UNICEF employee. Read more…

Tuvalu, Kiribati, Solomon Islands

Meantime, Tuvalu’s prime minister has declared a state of emergency, after the deadly cyclone caused widespread flash floods, severely affecting about half of his nation’s population.

The cyclone has also flattened homes, flooded fields and destroyed crops in Kiribati and the Solomon Islands, affecting thousands of families, said reports.

PAM Wreaks “Complete Devastation” in Vanuatu

Posted by feww on March 14, 2015

Super Cyclone PAM devastates Vanuatu islands

The category five monster cyclone smashed into Vanuatu islands in the South Pacific, wreaking “complete devastation.”

There are fears that dozens have lost their lives, and entire villages razed,  in what may be one of the region’s deadliest, and most destructive weather disasters.

Super Cyclone Pam, charged with sustained winds of 275km/h, gusting up to 340 km/hr [FIRE-EARTH estimates based on blog models,] slammed directly into the island nation late Friday.

“The damage is quite extensive in Port Vila but there are so many more vulnerable islands. I can’t even imagine what it’s like in those vulnerable communities,” said an emergency communications officer with World Vision in Port Vila, citing reports that entire villages in remote areas have been destroyed.

“The scene here this morning is complete devastation – houses are destroyed, trees are down, roads are blocked and people are wandering the streets looking for help,” said Tom Skirrow of Save the Children.

“Communications are down across much of the country with the total extent of the devastation unlikely to be known for several days.”

Some 44 people may have lost their lives in Penama province in the north-east of Vanuatu, said the UN’s Office for the Co-ordination for Humanitarian Assistance (UNOCHA).

“There are destructive winds, rain, flooding, landslides, sea surges and very rough seas and the storm is exceedingly destructive there,” said Australian Foreign Minister.

“While it is too early to say for certain, early reports are indicating that this weather disaster could potentially be one of the worst in Pacific history,” said a UNICEF spokesperson.

“The sheer force of the storm combined with communities just not set up to withstand it, could have devastating results for thousands across the region.”

Super Cyclone PAM Devastating South Pacific Nations

Posted by feww on March 13, 2015

PAM bearing down on Vanuatu after devastating several South Pacific nations

PAM a SUPERCHARGED category five tropical storm, is bearing down on Vanuatu after causing destruction in several South Pacific nations, including Kiribati, the Solomon Islands, and Tuvalu.

Vanuatu authorities issued a red alert nationwide, after the cyclone moved closer and was expected to hit the capital, Port Vila, Friday night.

Meantime, the Vanuatu Meteorological Services (VMS) issued the following warning:

At 12:00am local time, Severe Tropical Cyclone PAM was located at 17.8 degrees South 168.7 degrees East. This is about 45km east of Port Vila and 105km north northwest of Erromango. Severe Tropical  Cyclone PAM moved in a south direction at 17 km/hr in the past 3 hours.

The central pressure of the system is estimated at 900 hPa. Winds close to the centre are estimated at 250 km/hr. Severe Tropical Cyclone PAM is forecast to be at 20.2 degrees South 169.2 degrees East within the next 06 to 12 hours.

Very Destructive Hurricane Force winds of 255 km/hr is affecting SHEFA, MALAMPA and PENAMA provinces and slowly extending to TAFEA province.

Destructive Storm Force winds of 120 km/hr will continue to affect SANMA and TORBA provinces, slowly decreasing to gale force winds of 75 km/hr as the system moves further southward.

Very Destructive winds and very rough to phenomenal seas with heavy swells is affecting TORBA, PENAMA, SANMA, MALAMPA, SHEFA and TAFEA provinces. Heavy to torrential rainfalls and flooding, including flash flooding are expected over low lying areas and areas close to the river banks. Landslide is also expected. Coastal flooding from storm surge is expected near and along the coastal areas.

State of Emergency in Tuvalu

PAM has already caused flash flooding in the island nation of Tuvalu, located midway between Hawaii and Australia, forcing the authorities to declare a state of emergency.

The cyclone has also flattened homes, flooded fields and destroyed crops in Kiribati and the Solomon Islands, affecting thousands of families, said reports.

M 7.4 Quake Strikes Vanuatu Islands

Posted by feww on August 10, 2010

A Powerful Earthquake Measuring at least 7.4Mw Strikes Vanuatu Islands, Triggers Local Tsunami

The earthquake, epicentered at 168.02°E, 17.48°S, struck at about 05:24UTC  at a depth of about 45km, creating a small tsunami measuring up to a height of about 70 – 80cm.

There were no reports of casualties or major damage, as of posting; however, according to eyewitness reports the powerful quake shook the ground for about 10 seconds.

At last a dozen aftershocks, some measuring greater than 5.0Mw, have so far occurred. More aftershocks should be expected.

Gaua Volcano Eruption Intensifies

Posted by feww on April 28, 2010

Volcanic ash, poisonous gases, mudslide plague the tiny island

Vanuatu government officials may finally evacuate residents of Gaua Island

According to VAAC, Gaua produced volcanic ash plumes on  13 to 16 and again on 19 to 21 April, with most of the plumes rising to an altitudes of 3 km (10,000 ft) a.s.l. The advisories on 14-15 April noted that the plumes were mostly steam.

Vanuatu Geohazards Observatory said: “Field observations reported by the Geohazards officer in Gaua confirmed significant change of activity with ticker and higher emissions of ash columns (see photos in page 4). Since last week (end of march/beginning of April 2010) the ash plumes height dwell between 7000 and 10000 feet every day. Field reports also stated that the explosion sounds could be heard from the villages daily. Moreover, starting from the 3rd of April 2010 the volcanic bombes projections from Gaua volcano could be observed from all the coastal villages from the north to the south of the island with reports of the ashfall.”


The thick, steam-rich plume from Guau Volcano blows directly northeast in this natural-color satellite image acquired on April 24, 2010 by ALI aboard NASA’s EO-1 spacecraft. The thick steam is brighter white than the surrounding lower altitude clouds. Vegetation is green, as is Lake Letas. Vegetation to the south and west of the volcano, damaged by ash and acidic volcanic gases, is dark gray-brown. Image and Caption: NASA [edited by FEWW for brevity.]

Strong Quake Strikes Vanuatu – March 4

Posted by feww on March 4, 2010

Strong Earthquake Measuring Up to 6.6Mw Strikes 210 km N of Luganville, Espiritu Santo, Vanuatu

The quake struck at a depth of about 180km on Thursday, March 04, 2010 at 14:02:30 local time.

The mainshock was preceded by a Magnitude 5.0 foreshock.

Location
The epicenter was located at 13.616°S, 167.135°E, USGS said.

Tsunami Status
The hypocenter of this event was located too deep below the ocean floor to cause  a significant tsunami.

The quake occurred near 3 volcanoes: Gaua (80km), Suretamatai (40km) and Motlav (60km).

Gaua has been active sporadically since September 2009.

According to Global Volcanism Program website

On 29 January, the Vanuatu Geohazards Observatory reported significant changes in Gaua’s activity over the previous two weeks. They noted that since 16 January more gas was emitted and multiple explosions produced denser and darker ash plumes. During 22-29 January, the water level in the river to the E that Lake Letas feeds rose 10 cm. Gas-and-ash plumes rose 3 km and drifted S and W. On 24 January nearby villagers reported seeing ejected material from Strombolian activity. The Wellington VAAC reported that on 27 January an ash cloud was seen on satellite imagery. Strong explosions were seen and heard from East Gaua on 29 January. According to the VAAC, the Vanuatu Geohazards Observatory reported that gas-and-ash plumes rose to altitudes of 3 km (10,000 ft) a.s.l. and drifted S and W that same day.

Fire-Earth Moderators believe Gaua could resume activity in the coming days.
