quote:Etna eruptionSICILY, ITALY (BNO NEWS) -- Mount Etna, which is located on the east coast of the Italian island of Sicily, briefly erupted on late Wednesday evening, volcanists and witnesses said on Thursday.Etna is the largest active volcano in Europe with a standing of 3,329 meters (10,922 feet) high. It is also one of the most active volcanoes in the world and has seen increased activity in recent monthsOn Tuesday evening, the country's Institute of Geophysics and Volcanology said it had recorded a slight increase in volcanic tremors that reached its peak by 7 a.m. local time on Wednesday. It then quickly diminished.Hours later, at around 9.30 p.m. local time on Wednesday, a small eruption at Mount Etna sent lava down the mountain. "Shortly after [9 p.m.] an overflow began from the edge of the east pit crater," a statement from the institute said, adding that the lava flow was expanding in the direction of Valle del Bove.The eruption of Etna lasted only about an hour although the lava flow remained visible as of Thursday morning, lighting up the sky but posing no threat to the towns and cities near the volcano.As it was dark at the time of the eruption, it was not immediately clear if Etna had created an ash cloud. "The emission of volcanic ash is possible," the institute added.

Sicily looks on as Mount Etna erupts in spectacular fashionAfter reports of mysterious mass animal deaths around the planet, photos of a fierce volcanic eruption might confirm that the end of the world is nigh.Thankfully, these magnificent pictures of Mount Etna's latest eruption are merely a chance to revel in the awesome power of nature rather than a reason to start stocking up on canned goods.The 3,329-metre (10,922-feet) volcano erupted for around an hour yesterday evening, lighting up the sky on the small Italian island of Sicily.Etna is Europe's tallest and most active volcano and has seen increased activity in recent months yet its seismic might poses no immediate threat to the nearby towns and cities.According to the Italian Institute of Geophysics and Volcanology, a slight increase in Etna's volcanic tremors had been recorded on Tuesday, reaching its peak at 7am local time yesterday.The activity diminished but at 9:30pm local time on Wednesday night, Etna roared into life sending lava spewing down its sides.'Shortly after [9pm] an overflow began from the edge of the east pit crater,' a statement from the institute said last night.While the Sicilian communities near the volcano were not threatened by the latest eruption, it has not been established whether an ash cloud has been created by Etna's new activity.'The emission of volcanic ash is possible,' a spokesperson for the institute added.Large stones, known as volcanic 'bombs', and a sizeable quantity of ash was released by the volcano earlier this month, though no lava was released on that occasion.Known as 'Jebel Utlamat' in Arabic - meaning 'mountain of fire - Etna's name is thought to originate from the Phoenician word 'attuna', meaning 'furnace'.The volcano has been active for around half a million years, with 15,000 people killed during its most violent eruption in 1669.While its modern eruptions have rarely threatened the inhabited areas in the volcano's vicinity, a lengthy blast in 2002 was spectacular enough for footage of it to be included in Star Wars Episode III: Revenge of the Sith.

quote:Etna calmed down after renewed activity?Mount Etna, one of most the active volcanoes in the world, calmed down after two days of activity.Volcano experts said Monday in a report the volcano in Italy might have fallen back into a short calm phase before another active phase, “just around the corner.”The 11,000-foot tall volcano had a collection of black smoke more than 2 miles high and spewed lava and shards of magma more than 1,200 feet into the air on Sunday before it calmed down.The wind carried eruption fragments to towns of the large Sicilian city, Catania, but flight operations at the city were not affected.
quote:Etna roert zich weerDe grootste nog actieve vulkaan van Europa, de Etna, heeft zich de voorbije nacht geroerd op Sicilië. In de vroege ochtend werden zes explosies, gepaard met kleine aardbevingen tussen de 2,7 en 3,2 op de schaal van Richter, gevoeld. Niets ernstigs, ware het niet dat de Giro-karavaan komende zondag twee keer de Etna moet bedwingen. Opnieuw onvoorziene problemen dus voor de fel geplaagde Giro-baas Angelo Zomegnan.De luchthaven van Fontanarossa in Catanië is net voor de middag weer gedeeltelijk opengesteld voor de reizigers nadat de vliegtuigen een hele voormiddag aan de grond werden gehouden door de aswolk die boven Catania hing. De activiteit van de Etna verhoogde de voorbije nacht. Door de forse explosies barstten ramen en deuren uit hun voegen. Grote schade werd er niet aangericht."De etappe van zondag komt niet in het gedrang", predikt Zomegnan rust. "Er zijn al mensen aan het werk om de wegen die naar de top leiden, vrij te maken. We zijn niet ongerust." In de Italiaanse pers klinken de stemmen wat pessimistischer. Er is immers een kleine vrees dat de Giro-ploegen Sicilië niet met het vliegtuig zullen kunnen bereiken, wat hen heel wat minder recuperatie zal bezorgen in de aanloop naar de zondagrit. Na de zaterdagrit met aankomst in Tropea (Calabrië) moeten de renners per vliegtuig naar Messina, de startplaats zondag op het eiland Sicilië.Monte CrostisGarmin-Cervélo maakt zich inmiddels meer en meer zorgen over de veiligheid van de renners. Ex-rozetruidrager David Millar stapte samen met zijn ploegmakkers Brett Lancaster en Matthew Wilson naar de organisatie met de uitdrukkelijke vraag om iets te doen aan de aartsgevaarlijke afdaling van de Monte Crostis, in de beestachtige 14e rit."We hebben gehoord dat er zoals in het skiën netten zullen worden gespannen om ons op te vangen als we een bocht missen. Sommige bochten liggen op een klif", zucht Millar. De Schot hoopt dat de organisatie alsnog ingrijpt. "Als Zomegnan even nadenkt, weet ik zeker dat hij de juiste beslissing zal nemen. We zijn overeengekomen geen onnodige risicio's te pakken." (dea)

quote:Eruption Etna linked to quake in SpainROME, May 12 (Xinhua) -- The eruption of the Etna volcano in southern Italy early Thursday is connected to the earthquakes that rocked the Spanish region of Murcia, killing 12 people and injuring more than 170 others, a seismology expert said Thursday."We are currently witnessing an intense seismic activity in the entire Mediterranean area from Spain all the way to Malta which has a certain impact on regional volcanoes," said Domenico Patane, director of the Sicily office of Italy s National Geophysics Institute.Patane said volcanoes are like windows from where underground magma surfaces and it's normal that they respond to earthquakes occurring in a geographic proximity."The Spanish eastern coast hit by the quake, after all, lies close to Italy, in the Mediterranean. Both Spain and Sicily are on the same earth plate," he said.The earthquakes in Spain on Wednesday, which could be felt in Madrid, reportedly had their epicenter near the towns of Lorca and Totana in the Murcia region. The initial tremor of 4.4 magnitude was followed by a quake of about 5.2 magnitude.Around 2 a.m. Thursday people in Sicily felt the earth slightly tremble and heard the sound of an explosion coming from Etna's pit crater. < The eruption sent flying massive quantities of lava and volcanic ash, which spilled on the main town of Catania and other nearby villages but luckily caused no serious damage.The central airport was forced to close after it was submerged by the ash.Patane said there were no severe risks for local inhabitants but just for buildings and infrastructures that could be damaged by the ash and condensed lava."It's normal to have frequent small-scale quakes and minor volcano eruptions in the Mediterranean," he said, "We're used to seismic activity here in Sicily and recently several minor shocks have been felt also across the whole of Italy."Mount Etna is the highest active volcano in Europe, with a 45-kilometer-diameter crater.
quote:Quick post - you might want to watch some of the Etna webcams as the volcano looks like it might be starting to put on a show. Dr. Boris Behncke has been warning us that the volcano has been showing signs - such as small explosions - that a new eruptive period might be starting, and it looks like tonight might be the time. You can check out the seismicity as well to see the action begin to ramp up.
quote:(AGI) Palermo - An uncountable series of quakes have been recorded in Sicily. The strongest one had a magnitude of 3.1 and was recorded in the province of Messina, along the northern coast of Sicily that has been subjected to a persisting series of seismic events in the last few weeks. The quake was detected 3:01 am at a depth of a little more than 8 km. In the same area, a lighter 2.3 magnitude quake was recorded at 1:58 at approximately the same depth. . .

quote:Etna updatesUPDATE 09:45 UTC : Due to the volcanic activity and the ash concentration in the air, the (important) regional airport of Catania was closed since yesterday 18:12 (6:12 PM). The airport reopened this morning at 07:00 ( 7 AM).UPDATE 08:00 UTC : As stated below, the densely populated Catania area got a lot of ash showers covering cars and roofs with a gray layer.UPDATE : One video tells more than a 1000 words. This YouTube video was recorded by Klaus Dorschfeldt alias KdEtna. We encourage our readers to take a look at his great Etna Channel on YouTube. The strong eruption was short-lived (see in-depth text below), which explains why there are only daylight videos from this eruptionA few days after the resumption of Strombolian activity at the crater located on the east flank of the Southeast Crater cone, a new paroxysmal eruptive episode has taken place on the afternoon of 9 July 2011.This was the fifth eruptive episode since the beginning of 2011, and it was of shorter duration than its predecessors, but it produced ash and lapilli falls over the most densely populated area on Etna as far as Catania.From 4 to 7 July, the active crater has been the site of weak Strombolian activity, which from the evening of 7 July on showed a gradual increase; this was accompanied by a slow augmentation of the volcanic tremor amplitude.Small pyroclastic cones began to grow on the crater floor. The next morning, the increase in the intensity and frequency, and in the volcanic tremor amplitude, showed a clear acceleration, which seemed to indicate an imminent paroxysm. However, shortly after 06:00 GMT, the volcanic tremor amplitude showed an abrupt diminution, and the Strombolian activity at the active crater completely ceased.On the morning of 9 July, Strombolian activity resumed, and the volcanic tremor amplitude started to rise rapidly. Shortly after 12:00 GMT, lava overflowed the eastern rim of the crater, and then followed the path of the lava flows emitted during the previous paroxysms. At 13:45 GMT the Strombolian explosions blended into a continuous lava fountain, which was accompanied by the formation of a dense eruption column several kilometers high. The eruption plume, which was heavily charged with tephra, expanded south- and southeastward, leading to ash and lapilli falls in the populated areas between Nicolosi and Catania toward south, and Trecastagni, Viagrande and Acireale toward southeast.The paroxysmal activity lasted little longer than one hour, feeding a lava flow into the upper western part of the Valle del Bove, and generating strong emission of pyroclastic material; the activity showed a progressive diminution shortly after 15:30 GMT when volcanic tremor amplitude dropped to very low levels.It has finally to be noted that during the intial phase of the paroxysmal activity, at 13:41 GMT, a powerful explosion at the Bocca Nuova generated an intense ash emission.
quote:Etna spews again on TuesdayMount Etna in Sicily, Italy, erupted on Tuesday night resulting in the closure of the island’s main airport at Catania.This is the sixth time that Mount Etna, which is popular among tourists, has erupted in 2011.The last eruption occurred on Saturday. Italian officials had since said the 11,000-foot-tall volcano, one of the most active volcanoes in the world, had calmed down after a week of activity.Residents in surrounding areas had been warned however, that the Sicilian volcano might have fallen back into a short-lived slumber and another “active phase may just be around the corner.”
quote:Sicily's Mount Etna eruptsMount Etna volcano on the island of Sicily, southern Italy, started erupting again at the weekend, sending flames and sparks shooting 250 metres into the air, and flows of lava down its slopes. There were concerns that the ash could block flights out of nearby Catania airport, but the winds were blowing the ash away from the airport and no flights had been cancelled.The volcanic activity started on Saturday morning and continued through the day and overnight into Sunday, according to the Italian Institute of Volcanology.This is the fourth and the biggest eruption in July, after six months of calm, with lava fountains as high as 500 metres.No casualties or damage to property have been reported.Etna is one of the most active volcanoes in the world, and in the last few decades eruptions have been very frequent and lava flows have often threatened the villages surrounding the crater.

Sommige toeristen zijn zelfs moedig genoeg om zich vlakbij de hevige actie te wagen voor de perfecte foto.De jongste uitbarsting begon vorige week vrijdag kort voor middernacht. Naast de lava die vrijkwam, werden aswolken de lucht in gespuwd.Hoewel de uitbarsting er misschien gevaarlijk uitziet, richt ze geen al te grote schade aan. De lava vloeit immers weg langs kanalen. De aswolk daarentegen is wel hinderlijk voor toeristen en omwonenden. Ook de luchthaven van Catania moest enkele uren sluiten.

On the evening of 28 January 2013, the Bocca Nuova - the largest of the summit craters of Etna - has been the site of a new episode of vigorous Strombolian activity. This episode was similar to, though slightly less intense than, the episodes of 16 and 18 January, but it was accompanied by weak Strombolian activity at the New Southeast Crater (NSEC).During the preceding days, the summit craters had been degassing strongly, in particular the NSEC, where for a brief period on the evening of 27 January, weak incandescence was visible. The crater had last produced an episode of Strombolian activity on 22-23 January 2013 (see 23 January 2013 update). On the morning of 28 January, gas emission from the NSEC was often rhythmic and pulsating; at times the gas puffs appeared "dirty" because they contained modest amounts of fine pyroclastic material (Fig. 1 and 2). The degassing was not accompanied by any noise to be heard at a distance of a few kilometers.Starting at 07:46 GMT (=local time -1) on 28 January, the eruptive vent located in the southeastern portion of the crater floor of the Bocca Nuova, produced small puffs of dark volcanic ash, which rarely rose more than 150-200 m above the crater rim (Fig. 1 and 2). Initially, these ash emissions were separated by intervals of 5-10 minutes, but later they became more and more frequent, with one emission every 1-3 minutes in the late forenoon. Some of the emissions were accompanied by loud rumbling noises well audible at Piano del Vescovo, about 7.7 km southeast of the Bocca Nuova. Ash emissions continued at least until 14:00 GMT, when weather conditions deteriorated and precluded any visual observations.Shortly after 17:00 GMT, the visual surveillance cameras of the INGV-Osservatorio Etneo showed the beginning of mild Strombolian activity within the Bocca Nuova (Fig. 3, top frame). Contemporaneously, the volcanic tremor amplitude recorded in the summit area started to rise, accelerating notably around 19:00 GMT and reaching a peak shortly thereafter. During the same time interval, the Strombolian activity within the Bocca Nuova intensified, with jets of incandescent bombs and scoriae that often rose several tens of meters above the crater rim.From 17:40 GMT onward, weak and discontinuous Strombolian activity was visible at the NSEC (Fig. 3, second and third frames). Some explosions launched incandescent bombs up to 30 m above the crater rim. This activity reached its greatest intensity between 19:00 and 19:30 GMT, and from 19:40 GMT rapidly diminished to be followed by the emission of a conspicuous column of white vapor, which continued during the whole night and through the following day of 19 January.At the Bocca Nuova, however, the intracrater Strombolian activity - which was presumably accompanied by the emission of lava onto the crater floor - continued until about 00:15 GMT on 29 January. Starting around 21:50, the activity had shown signs of gradually diminishing and more and more discontinuous, even though some explosions between 22:00 and 23:00 GMT were particularly violent (Fig. 3, bottom frame). The diminution of the vigor of the eruptive activity was accompanied by a rapid decrease in the volcanic tremor amplitude.As for the Bocca Nuova, this episode - the fourth from this crater during this month, after those of 10-15, 16 and 18 January - was rather similar to its predecessors. The peak values attained by the volcanic tremor amplitude were slightly lower than those of the 18 January episode, and significantly lower than those of the 16 January episode. The single source of the activity was once more the intracrater cone leaning against the southeastern base of the inner crater wall; unfortunately, the harsh weather conditions in the past few weeks have precluded any field visit to the crater rim aimed at observing the morphological changes caused by the recent activity.A new element in the eruptive episode of 28 January 2013 is the Strombolian activity at the NSEC, which accompanied during the first two-and-a-half hours of the episode the Strombolian activity within the Bocca NuovaThis is indeed the first occurrence of simultaneous eruptive activity at two of Etna's summit craters since about 12 years; in contrast, during the period of summit activity of 1995-2001, it was rather normal to see contemporaneous activity at two, sometimes three and rarely all four of the summit craters. One particularly noteworthy event of this type was the sequence of paroxysmal episodes that occurred within a few hours on 4 September 1999: first a sub-Plinian explosive episode at the Voragine, followed by lava fountaining within the Bocca Nuova, and finally an episode of Strombolian activity at the (old) Southeast Crater, which culminated in the fracturing of its cone from the summit to the base.

The dramatic scene was captured in a video by Klaus Dorschfeldt, a videographer and webmaster at Italy's National Institute of Geophysics and VolcanologyMount Etna, one of the world's most active volcanoes, had emitted signs of an imminent paroxysm in recent weeks. On Jan. 22, lava and strong flashes in the volcano's New Southeast Crater were clearly visible from the Sicilian foothills; these often herald a new paroxysm: short, violent eruptive bursts.Dorschfeldt said he knew Mount Etna's recent signals could precede new activity. "[I've] followed the activity of Etna for many years, and with time you learn to know it as if it were your friend," he said in an email interview. "Following it constantly [you] learn to be a keen observer and a minor change can lead to something important," he told OurAmazingPlanet.The tallest volcano in Europe, Mount Etna is almost constantly spewing gas or lava. Its Bocca Nuova crater also erupted earlier this year, from Jan. 10 to Jan. 20. In 2011, Etna's violent bursts were spotted from space.

De nabijgelegen luchthaven van Catania, aan de noordoostkust van Sicilië, hoefde niet gesloten te worden. Vorig jaar waren er acht van dergelijke uitbarstingen van de Etna.
quote:Etna's activity last week was actually a warming up for the show on SaturdayMuch of last week, we were focused on the activity at Italy’s Etna. The week ended with some lava flows creeping down the volcano and, for a day, things had settled down. Well, little did we know that Etna was actually just warming up. During the night of February 23 (Saturday), the volcano unleashed a remarkable explosive volley, producing lava fountains that toward 800 meters over the crater on the southeast slopes of the volcano. Video taken by Dr. Boris Behncke of the Osservatorio Etneo (above) shows just how powerful the eruption was, with the pulsing and roaring of the lava as it was explosively thrown from the vent near the new Southeast Crater.Let’s try to put a 800 meter lava fountain into some perspective. 800 meters is ~2,624 feet. The height of the Empire State Building in New York is ~1,250 feet (roof height — add the tower and its ~1,454 feet). So, lava was fountaining from the crater on Etna as height as almost 2 Empire State Buildings on Saturday night (see image on top).Now, the factors that go into the height of a lava fountain include the magma supply rate (how much magma is being fed into conduit to erupt), the gas content of the magma — the higher the gas content, the more explosive the eruption will be, and the geometry of the crater. This eruption of Etna likely had a high rate of magma supplied to the vent and relatively high gas content to produce such a lava fountain. However, it isn’t even close to the record for tall lava fountains. The record for historic (and confirmed) lava fountain height is the 1986 eruption of Izu-Oshima in Japan that topped out at ~1,600 meters. When Tarawera erupted in 1886, the lava fountains in that basaltic eruption were estimated to be as tall as 2,000 meters (2 kilometers)* — that’s ~6,561 feet or 5.25 Empire State Buildings worth of lava fountain. The eruption of Tarawera did not have any geologists to accurately measure the height of the fountain, so the 2,000 meters height is based on local people’s recollection of the eruption. However, 2,000 meters isn’t unreasonable based on the eruptive rate and gas content of the Tarawera basalt. To take it even higher, the lava fountains from the 1779 eruption of Vesuvius were thought to have reached 3 kilometers (9,800 feet)!By Sunday morning, the new cone built by Saturday night’s (and earlier in the week) lava fountains was clearly visible — a dark, black cone of volcanic debris starkly contrasted against the white mountain snows (see below). It is remarkable to see how quickly these volcano features can grow during these periods of intense activity. Lava flows are still snaking down the volcano as well — so it seems like Etna’s February is still going strong.
