A state of emergency has been declared in communities near the 100 square mile glacier, however no damage or casualties have been reported so far.

“We do not at this moment know the full extent of the eruption but a team is flying over the site now to evaluate the situation,” said said Vidir Reynisson, the department manager for the Icelandic Civil Protection Department.

The Icelandic public radio station RUV reported that three Iceland-bound Icelandair flights, out of Boston, Orlando and Seattle, had been ordered to turn back to the United States.

"Ash has already begun to fall in Fljotshlid and people in the surrounding area have reported seeing bright lights emanating from the glacier," RUV said on its website.

"There is currently no sign of flooding, but it could be imminent according to experts," it added. "It is not clear exactly where the eruption is taking place but it is being investigated."

Eyjafjallajökull (pronounced [ˈɛɪjaˌfjatlaˌj½kʏtl̥]) is one of the smaller glaciers of Iceland. It is situated to the north of Skógar and to the west of the larger glacier Mýrdalsjökull.

The icecap of the glacier covers a volcano (1,666 m in height) which has erupted relatively frequently since the Ice Age. The latest eruption began in March 2010, and the most recent eruption before then was from 1821 to 1823, causing a fatal glacier run. A previous eruption was in 1612. The crater of the volcano has a diameter of 3–4 km and the glacier covers an area of about 100 km².

The south end of the mountain was once part of the Atlantic coastline. As the sea has since retreated some 5 km, the former coastline has left behind sheer cliffs with a multitude of beautiful waterfalls, the best known of them being Skógafoss. In strong winds, the water of the smaller falls can even be blown up the mountain.

Between 3 and 5 March 2010 there were measured close to 3,000 earthquakes at the epicenter of the volcano. Most were very small but some could be detected in the nearby towns.[1] The first news of an eruption arrived on 20 March. The towns of Fljótshlíð and Markarfljót are to be evacuated, and flights destined to Reykjavík on Icelandair will be diverted.

Breaking News: An eruption Started by Eyjafjallajökull Glacier at Midnight
At about 11.30 on Saturday night some residents in Fljótshlíd noticed that an orange colored stroke appeared behind the glacier Eyjafjallajökull. The area has been under constant surveilance in recent days because of earthquake activiety and it was clear that as feared. an eruption had started. Immediately an evacuation plan was put into effect for the 400 people in the area who were thought to be in danger. The operation was successful and at five o'clock all had been regisered at Hvolsvöllur, where a rescue center was set up.

The ereption is located in Fimmvörduhals, a passager between two glacers, Eyjafjallajökull and Mýrdalsjökull. A popular walking path goes through the area, from Skógafoss in the south to Thórsmörk. Everty summer hvdereds, and perhaps thousands, walk through the area.

Scientists say the eruption seems to be small. It consists of a row of ten paralell strokes. Because the eruption in not under a glacier, the danger is much smaller than it would otherwise have beeen.

We will continue to bring news about the eruption during the day.

Volcanic Eruption: Actually In Fimmvörðuháls, All Is Well
But who knows what's going to happen?

Icelandic state news outlet RÚV has posted a public announcement in English regarding the volcanic eruption which we reported on earlier. Everyone is safe and all is well, at least right now. Read their announcement after the jump.

While it was initially believed the eruption was occurring under Eyjafjallajökull glacier, it has since been revealed that the main crack is at Fimmvörðuháls, which is a popular walking route, especially for travelers hiking Landmannalaugar. The eruption occured at precisely 23:34, according to RÚV. Oh and they're saying now that the flames are rising.

Here's RÚV's announcement, in English.

Information on eruption

Evacuation in response to the volcanic eruption in Eyjafjallajökull glacier has concluded after an extremely rapid response, according to officials. Everyone known to have been in the area has been brought to safety and is now accounted for.

Currently the eruption appears to be limited to an area where there is little ice - meaning there is no longer believed to be an imminent threat of a flood unless the eruption spreads along the fault line.

The eruption is however close enough to the glacier to warrant concern and a state of local emergency has been declared and emergency response plans initiated. The National Emergency coordination centre in Skógarhlið, Reykjavik, has been activated and is operational. Response teams have been dispatched to the area and the situation is being closely monitored. The Local Emergency operations centre has been established in Hella.

Three Red Cross mass care centres have been opened in the villages of Hella, Hvolsvöllur and Vík. Red Cross volunteers are ready to receive people. The Red Cross helpline, 1717, is open and able to provide information about the eruption to members of the public.

Sheveluch volcano, Kamchatka, Russia - John Seach
Posted by John Seach
Eruptions occurred at Sheveluch volcano, Kamchatka during the week 11-18 March 2010. Ash emissions reached a height of 7000 m. Lava flows continue down the flanks.

quote:

Shiveluch (Russian: Шивелуч) is the northernmost active volcano in Kamchatka Krai, Russia. It is sometimes called Sheveluch (Шевелуч) or Sopka Shiveluch. It is one of Kamchatka's largest and most active volcanoes.
Shiveluch began forming about 60,000 to 70,000 years ago, and it has had at least 60 large eruptions during the Holocene.[3] During this era, the most intense period of volcanism – including frequent large and moderate eruptions – occurred around 6500 – 6400 BC, 2250 – 2000 BC, and 50 – 650 AD. This coincides with the peak of activity in other Kamchatka volcanoes. The current active period started around 900 BC. Since then, the large and moderate eruptions has been following each other in 50-400 year-long intervals.[4] Catastrophic eruptions took place in 1854 and 1956, when a large part of the lava dome collapsed and created a devastating debris avalanche.[5]

The most recent eruption of Young Shiveluch started on August 15, 1999, and continues as of 2009.[3]
Shiveluch belongs Kliuchevskaya volcano group.[5] There are three elements of the volcano: the stratovolcano Old Shiveluch (Старый Шивелуч); an ancient caldera; and the active Young Shiveluch (Молодой Шивелуч), with an elevation of about 2,800 metres (9,186 ft).[6] Shiveluch is one of Kamchatka's largest and most active volcanic structures.[3] It is a stratovolcano composed of alternating layers of solidified ash, hardened lava and volcanic rocks.[7]

The nearest settlement from the volcano is Kljuchi, situated 50 km from the mountain. The settlement is small enough to evacuate rapidly in case of a major eruption.[5]

'Vulkaan zorgt voor tsunamigevaar zuiden Italië'

Een onderzeese vulkaan voor de kust van de Italiaanse stad Napels is instabiel, en kan bij een uitbarsting een verwoestende tsunami veroorzaken.

Daarvoor waarschuwt de voorzitter Enzo Boschi van het Nationale Instituut voor Geofysica en Vulcanologie in de Italiaanse krant Corriere della Sera. Het gaat om de vulkaan Marsili, waarvan de krater zo'n 450 meter onder de waterspiegel van de Tyrreense Zee ligt.

Volgens Boschi zijn de wanden van de vulkaan instabiel, en heeft de magmakamer van de Marsili zich gevuld. "Dat wijst er allemaal op dat de vulkaan actief is en ieder moment zou kunnen uitbarsten," zegt Boschi, die de Marsili vergelijkt met een hogedrukpan.

Tsunami
De eruptie zou volgens hem een sterke tsunami kunnen veroorzaken, die de kusten van Zuid-Italië en Sicilië zou overspoelen.
Boschi noemt zo'n uitbarsting een zeer reëel risico, maar zegt dat het gevaar dat de vulkaan oplevert moeilijk is in te schatten of te voorspellen. Dat komt omdat het moeilijk en kostbaar is om voldoende meetapparatuur op de enorme onderzeese vulkaan te plaatsen.

Koryaksky volcano, Kamchatka, Russia
Seismic activity has increased at Koryaksky volcano in Kamchatka. Over the past 24 hours there have been 13 earthquakes over magnitude 3.

quote:

Kamchatka, Russia

53.32 N, 158.68 E
summit elevation 3456 m
stratovolcano

Koryaksky is a tall conical stratovolcano located NW of Petropavlovsk-Kamchatskiy. The volcano is considered one of the most beautiful in Kamchatka. It can be climbed in 4-8 day trips from Petropavlovsk. Crampons and ice axe are needed for this snow climb, as well as experience in mountaineering. There are two glaciers on the eastern slope; 4.2 and 1 km in length.

Koryaksky volcano is grooved by deep radial ravines. The slope of the lower cone is 20 deg rising to a maximum of 30-35 deg in the upper cone. The absolute height of the volcano is 3456 m, and a relative height of 2300 m in the north and 3300 m in the south.

The western part of the summit ridge contains a crater 180-200 m diameter, with walls 20-30 m high. The crater is breached to the south, with a short lava flow.

Fumaroles of the volcano are located on the northwest slope at an elevation of 3000 m. The main gas jets discharge from the fissure that formed during the 1957 phreatic eruption. There are some low temperature fumaroles in a glacier covered, summit crater.

Future eruptions at Koryaksky volcano have the potential to be highly explosive. Probable location for eruptions are the northwestern side which is weakened by transecting faults.
