Mount Vesuvius, Italy: Map, Facts, Eruption Pictures, Pompeii. Mount Vesuvius Introduction Vesuvius is the only active volcano in mainland Europe, and has produced some of the continent's largest volcanic eruptions.
Located on Italy's west coast, it overlooks the Bay and City of Naples and sits in the crater of the ancient Somma volcano. Vesuvius is most famous for the 79 AD eruption which destroyed the Roman cities of Pompeii and Herculaneum. Though the volcano's last eruption was in 1944, it still represents a great danger to the cities that surround it, especially the busy metropolis of Naples. La convergence lithosphérique.

Aðspurður hvort slíkt geti orðið hættulegt svarar hann: „Ef það er verið að bora niður í stórar sprungur þar sem mikil spenna hefur byggst upp, þá gæti þetta orðið hættulegt.

Atlantic Ocean Volcanism, OIBs, Tholeiites and Basanites (Ocean Island Basalts) Iceland is a large mid-North Atlantic island, built entirely of basalts and fractionated derivatives.
It is located right on the Mid-Atlantic ridge spreading centre but is the locus of more than it's share of volcanism, hence is called a 'Hot-Spot'. In the literature frequent reference is made to "The Icelandic Plume". Jonfr.com home par Jön Frimann. Renewed earthquake activity in Hekla volcano Today (14-April-2014) an earthquake swarm took place in south part of Hekla volcano.
The earthquake swarm took place close to Vatnafjöll mountains. This area is made up of crater rows from earlier eruptions. The largest earthquake in this swarm had the magnitude of 2,9 and the depth of 8,6 km.

Volcanology. A volcanologist sampling lava using a rock hammer and a bucket of water Modern volcanology[edit] In 1841, the first volcanological observatory, the Vesuvius Observatory, was founded in the Kingdom of the Two Sicilies.
Seismic observations are made using seismographs deployed near volcanic areas, watching out for increased seismicity during volcanic events, in particular looking for long period harmonic tremors, which signal magma movement through volcanic conduits.[1] Surface deformation monitoring includes the use of geodetic techniques such as leveling, tilt, strain, angle and distance measurements through tiltmeters, total stations and EDMs. This also includes GNSS observations and InSAR.[2] Surface deformation indicates magma upwelling: increased magma supply produces bulges in the volcanic center's surface. Temperature changes are monitored using thermometers and observing changes in thermal properties of volcanic lakes and vents, which may indicate upcoming activity.[3] See also[edit]
Supervolcan Toba : un monstre en sommeil. Volcanologie. Le super volcan de Yellowstone: Documentaire 5/5. How many active volcanoes are there in the world? The answer to this common question depends upon use of the word "active. " At least 20 volcanoes will probably be erupting as you read these words (Italy's Stromboli, for example, has been erupting for more than a thousand years); roughly 60 erupted each year through the 1990s; 154 in the full decade 1990-1999; about 550 have had historically documented eruptions; about 1300 (and perhaps more than 1500) have erupted in the Holocene (past 10,000 years); and some estimates of young seafloor volcanoes exceed a million. Because dormant intervals between major eruptions at a single volcano may last hundreds to thousands of years, dwarfing the relatively short historical record in many regions, it is misleading to restrict usage of "active volcano" to recorded human memories: we prefer to add another identifying word (e.g.
"historically active" or "Holocene volcano"). The definition of "volcano" is as important in answering the number question as the definition of "active. " Trapps de Sibérie. Volcanoes: Renewable Energy's Next Big Eruption. Renewable energy, for all its planet-saving prowess, can be a bit fickle.
A windmill without blustery gusts is about as effective as solar panels on a cloudy day. Even hydropowered dams, renewable energy's workhorse, can have trouble clocking in during extended drought. Luckily for energy companies, there's a new kid in town. Earlier this week, geothermal energy developers announced summer plans to pump 24 million gallons of water into the side of the Newberry caldera, a dormant volcano in Central Oregon. The goal? Said Susan Petty, president of Seattle-based AltaRock Energy, to the AP: "We know the heat is there. Normally, the capital costs of exploring a new geothermal energy source are prohibitively high. To help allay the costs, the Department of Energy matched the $21.5 million investment of Google and other private investors with an eye towards geothermal's longterm potential.

Spewing clouds of smoke, ash and steam thousands of feet into the sky, these dramatic images and video (below) show the raw power of an undersea volcano erupting.The spectacular columns blasted out of the South Pacific yesterday six miles off the coast of Tonga's main island Tongatapu.
The eruption can be seen clearly from the capital, Nuku'alofa, although residents only reported seeing smoke rising from the sea on Wednesday, two days after it is believed to have begun But authorities said today that the eruption does not pose any danger to islanders at this stage, and there have been no reports of fish or other animals being affected.No warnings have been issued to the coastal villages close to the volcano, which is one of 36 undersea volcanoes clustered in that area. The situation is being helped by trade winds which continue to blow gas and steam away from the island.
Volcanoes Help Keep the Earth Cooler. The fiery power of a volcano is not something we usually associate with good news.
Ash from Iceland’s Eyjafjallajokull volcano, for example, caused a major disruption in air travel across western and northern Europe in April and May 2010. Yet behind all that smoke is a silver lining. New research that's being published in Geophysical Research Letters indicates that we can thank volcanoes for the fact that the Earth has warmed less during the first ten years of the 21st century than climate models suggested it would. The average concentration of carbon dioxide in the atmosphere did rise between 2000 and 2010. Caldeira de Yellowstone. Éruptions volcaniques massives et supervolcans.

Il Vesuvio attualmente è caratterizzato dalla presenza di un sistema idrotermale, che alimenta un campo di fumarole all'interno del cratere, ed è sede di una modesta sismicità rappresentata da alcune centinaia di piccoli terremoti per anno.
