WELLINGTON, May 13 (Reuters) - Volcanic activity at New Zealand's Mount Ruapehu is increasing and an eruption could occur at any time, scientists warned on Tuesday. The volcano in central North Island, famed as a location in the "Lord of the Rings" film trilogy, last erupted on Sept. 25 2007, spitting 2 metre (6 feet) boulders distances of up to 2 kms (1.5 miles). Ruapehu's elevated alert level has not been changed, but scientists said on Tuesday that activity within the mountain was greater, with high levels of gas spewing out, a warmer than average crater lake and ongoing volcanic tremors. "The volcano remains in a status of unrest and the possibility of further activity remains. If further eruptions occur, they may occur without warning," Geological and Nuclear Sciences (GNS) said in a statement. Last September's eruption injured a climber after a boulder crashed through the roof of a hut near the summit where a party of four climbers were staying. The highest mountain in New Zealand's North Island at 2,797 metres (9,177 feet), Mt Ruapehu has one of the most active crater lakes in the world. In March 2007 a mudflow, or "lahar" flowed down the side of the mountain after the crater lake overflowed, and large eruptions in 1995 and 1996 blanketed the surrounding area in ash. In 1953 a lahar swept away a railway bridge at Tangiwai at the base of the mountain and 151 people were killed when an Auckland-to-Wellington train plunged into a river.

autre orage

By Antonio de la Jara PUERTO MONTT, Chile (Reuters) - A towering plume of ash from an erupting volcano in Chile's remote Patagonia could rain down on the surrounding area and cause devastating damage, a volcano expert warned on Friday. Luis Lara, a scientist with the government's geology and mining agency, said the column, which has soared 7.5 miles (12 km) into the air, was at a critical stage. An abrupt descent would blanket vast areas with deadly hot gas, ash and molten rock, he said. Authorities have evacuated thousands of people from the immediate vicinity of Chaiten volcano, 760 miles south of the capital Santiago, and are forcing people within a 30-mile (50-km) radius to leave. Chaiten began erupting eight days ago for the first time in thousands of years. "We are at a critical point of this phase given the characteristics (of the eruption) have remained the same for several days," Lara said. "The volcano is now at its limit and one possibility is that the column could collapse quickly, generating flows of ... material down its ravines," he said. The column might descend gradually and do little damage. But in the worst-case scenario, the ash and fiery material would engulf the town of Chaiten, just 6 miles from the volcano, and the areas around it. Lara said the volcano could rumble on for years and suggested that the town, which is now deserted, be moved. SOUTH ARGENTINA ALSO HIT HARD The cloud has also caked towns on the Argentine side of the border with ash. Satellite images show a white stripe smeared across the southern part of the continent. Ash that had drifted as far as Buenos Aires dissipated on Friday, and some airlines that had canceled flights overnight resumed service. But towns in Argentine Patagonia were badly affected, with residents complaining of sore throats due to ash inhalation and being forced to pay exorbitant prices for bottled water because ground water had been contaminated. Views of dramatic Andean peaks that serve as a natural border between the two countries were obscured by clouds of ash in the Argentine settlement of Trevelin, a popular tourist spot about 60 miles from the volcano. Shop owners put wet cloths and cardboard on the doorsteps as doormats to stop prospective customers from tracking ash into their premises. But they were losing the battle. Some residents wore masks, but many did not. "We keep cleaning, but still everything gets dirty at the same time. The dust and ash gets everywhere," said a hotel employee named Alejandra. Back in Chile, many evacuees had no idea when they might be able to return to their homes and lives, and their frustration was mounting. "We've been here so many days and no one tells us anything," said Iluminada Ide, who was evacuated to the southern Chilean town of Puerto Montt. "We can't go on like this."

FIVE FEET OF ASH: Smoke and ash billow from the Chaitén volcano in southern Chile, which erupted on May 2, 2008, after lying dormant since circa 7,400 B.C. In this infrared image, captured on May 5 by NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Terra satellite, the 18-mile- (29-kilometer-) high plume wafts over Argentina on its way toward the Atlantic Ocean on the right. Clouds appear turquoise due to water crystals, whereas the warmer ash stands out as grayish-white. The explosion forced the evacuation of a nearby town, and some areas were buried under five feet (1.5 meters) of ash. http://www.sciam.com/gallery_directory.cfm...A64B135AA52CB17

si le cone s'effondre le pire est a venir

je suis aller a saint-michel-des-saints aujourd'hui pis y restait encore de la neige aussi dans la forêt mais j'avais pas d'appareil photo.

le mont etna

Europe most active volcano wakes up Sunday 11 May 2008 From its 3350 meters, Mount Etna got back in activity to spew lava and spread ashes clouds in the air. The last major eruption happened in 2001 when 200 earthquakes at 4.2 on the Richter scale shaked the Sicilian plains.

l'effondrement finale est proche selon plusieurs experts

étant a sainte-agathe-des-monts aujourd'hui après avoir été skier a saint-sauveur bien sur j'ai pu observer un sun halo

Mauna Loa - Earth's Largest Volcano shows Lava on it's surface in Google Earth/Map Satellite Image by Lisa Long Page 1 of 1 page(s) http://www.opednews.com Tell A Friend If a volcano erupts and no one sees it.. does that mean it is not happening? I have spent days working to get media and government attention to the fact that there are red-white hot spots shown in a newly uploaded Google Earth image of the Mauna Loa Volcano. These very clear satellite images show bright red, white, yellow and orange hot spots on the SW Rift Zone of Mauna Loa, THE LARGEST VOLCANO IN THE WORLD, located on the Big Island of Hawaii, where I live. I have looked at images on Google Earth of Mauna Loa several times over the past year or two. About three weeks ago a friend of mine mentioned strange gases, noises and helicopters above the Hawaiian Ocean View Estates (H.O.V.E.) subdivision. I had heard these rumors before, so I spent several hours looking at Google Satellite images of Mauna Loa. I found no unusual buildings or activity on the volcano at any of these times. However, this time it was different. This week Tuesday, May 6, 2008, a farmer mentioned her Swiss Chard was burned by a mysterious ground hugging milky cloud that moved from above her farm down thru the fields and even thru a small farm building she had. She said the gas did not smell like sulfur.. it had a very bad smell and she knew it was something different. She took samples of the chard that was burned, and swaps off her windows and had them tested by the state of Hawaii. They told her they could not find anything on the samples. As a gift to her, I printed off an aerial view of her farm in H.O.V.E. and gave it to her. As she left, I closed the browser.. but something red caught my eye, so I decide to check it out later. Back at my desk, and starting on Google Earth at H.O.V.E., I followed up the ridge and realized as I approached the summit of the Volcano that something was much different. Small red hot places doted the landscape. I zoomed in for a closer look.. chicken skin. This was a different image, I realized, Google had updated their image and Mauna Loa was awakening! http://www.opednews.com/articles/life_a_li...____earth_s.htm

y faut chercher http://www.sfgate.com/cgi-bin/article.cgi?...9/TRO9VO1C3.DTL

depuis quelques jours l'activité volcanique a Hawaï a beaucoup augmenter

Il était en dormance depuis 3 sièecles! et la derniere eruption majeur il y a 9 millénaire

Non il n'y a pas de webcam le chaiten n'était pas considérer comme un volcan potentiellement actif donc aucune surveillance...

en effet c'est très interessant on voit que le jet stream articque s'emplifie et descend littérallement sur le québec, l'ontario et les maritimes voila pourquoi nous sommes les plus touchés lors d'une éruption majeur, une grande partie de l'europe est touché aussi par cet air articque

Non sa va affecter l'ensemble du globe. Un volcan qui fait eruption en alaska n'affectera pas le climat comme un volcan qui fait erruption près de l'equateur. Pour une raison bien simple, plus le volcan est loin de l'equateur plus il sera exposer a de l'air froid et de l'air froid en altitude rendant la monté de la colone de cendres et souffre plus difficile aussi en outre la teneur en souffre d'un volcan loin de l'équateur est très faible donc peu de conséquence pour le climat global plus d'effet local dans ce cas la.

et pour plus de preuve aller sur google news et chercher global cooling et global warming pour voir le ratio de nouvelles entre les deux

on ouvrent un forum de grammaire??? lol Pour en revenir au sujet l'activité du volcan a encore augmenter ce matin et une forte détonation vers minuit a fait fuire le restant des personnes encore sur place

lors de l'éruption du pinatubo il y a même eu un typhon qui passa par la le 3e jour fesant retomber une partie des cendres volcaniques en boue nauséabonde. Au bout du 5e jour un tremblement de terre acheva la destruction. La totale quoi

voici une orage volcanique qui c'est produit hier soir au chilie

selon plusieurs runs du gfs certain flocons pourrait ètre observer dans certaine region du quebec lors de la nuit du 12 au 13 mai peut-être même les basses laurentides. Ce sera surement le dernier gèle de la saison pour plusieurs secteurs. la dépression ce déplacerais le long de la cote atlantique nous positionant du coté froid.

en effet le vent répartit les particules en suspension partout dans l'atmosphère plus le volcan en libèrera plus le voile dans la haute atmosphère réflectera la lumière du soleil

bin si on lis le premier article que j'ai poster on peut lire que les cendres qui montent dans la haute atmosphere sont a l'abris de l'humidité de la basse atmospère et peuvent rester en suspension pendant des semaines voir même des mois et affecter globalement le climat de la terre. Comme en 1991 lors de l'éruption du Pinatubo ou encore pire en 1815-1816 l'année sans été (http://fr.wikipedia.org/wiki/Ann%C3%A9e_sans_%C3%A9t%C3%A9) causé par le volcan Mont Tambora De plus, on ne sait pas si le volcan demeurera actif quelques jours,semaines ou mois voir même plusieurs années
