		Eruption phreatomagmatic (mixture of the magma with superficial or subterranean water) or magmatic: the explosions of gas go accompanied with the exit of lava in the shape of fragments (ash, lapilli, blocks and volcanic bombs according to their size in which they solidify in their traveled through by the air.
		In any of the settings of volcanic activity, still without eruption, they would be able to be produced new flows of debris (lahars), by the dragging of the loose material that still exists in the interior of fractions and you split high of the volcano, in case to be produced rains.
		A smaller eruption on the morning of 26 September was limited to the area of the lake, and formed green-yellow semicircular zones of mud and sulfur up to 75 m in diameter.

	volcanic eruption animations
		Most volcanic eruptions are "builders," adding thin layers of lava or ash to the sides of a volcano, slowly building the easily recognized cone-shaped volcanoes seen around the world.
		The eruption begins with the invasion of the fresh lava along the old eruption channel leading to the summit vent.
		The second stage of the eruption is effusive: a large mass of gas-free lava percolates to the summit vent, fills it, and flows down the sides of the cone.

	Volcanic Eruption in Vatnajökull
		On December 18 at 09:20 GMT, an eruption began at the southern caldera rim of the Grímsvötn caldera, in Vatnajökull, Europe's largest glacier.
		The eruption tremor has a fairly constant amplitude which is directly related to the vigor of the eruption, lava production and gas release.
		Tremor bursts have, however, only been observed in association with subglacial eruptions and are most likely generated in the forceful struggle between the submerged eruption vents and the surrounding meltwater.

	Mauna Loa Eruption History
		Typically, these eruptions began in the summit caldera, Moku'aweoweo, with a curtain of fire (which is a 1 to 2 km line of lava fountains).
		The eruption started at the summit (in Moku'aweoweo crater, which is the grey oblong area in the lower-left corner of the image to the left), extended in to the upper Southwest Rift Zone, and then migrated to the Northeast Rift Zone on the first day of the eruption.
		As eruption rates declined, the main a'a flow evolved from a simple narrow lobe with an efficient channel that delivered virtually the entire vent output to within 1 km of the flow toe, to an upright-stagnating channel system characterized by levees, blockages, ponds, and complexly branching overflows.

	Eruption by Van Halen Songfacts
		Eruption is a very skillful solo but even if he does tap for speed it doesnt mean its a bad solo.
		Eruption is hands down the best guitar solo ever, it may not have the soul of Hendrix, but you can tell the passion is there along with the skill.
		Eruption has to be one of the best guitar solos ever and when I ask my friends to listen to it, they heed no word I say.

	eruption (Site not responding. Last check: )
		The explosive eruption shot a column of ash and steam that rose 19 km into the air, and generated pyroclastic flows that poured down the mountain.
		This was a Plinian type eruption, characterized by the explosive eruption of tephra, ash and pyroclastic flows.
		Before the 1991 eruption Mt. Pinatubo was 1,745 meters high, after the eruption a collapse caldera had formed that was 2.5 kilometers across, lowering the height of the volcano to 1,485 meters.

	19 May 1915 Eruption of Lassen Peak
		The characteristics of the eruption that occurred late on the afternoon of 22 May 1915 are discussed in Eppler (1987), and a more expanded treatment of the eruptions of May 1915 and a discussion of the lahars that they generated may be found in Eppler (1984).
		For this work, a volcanic blast is defined as the effect of a violent eruption that causes significant destruction to the area surrounding the volcanic edifice, with an inferred significant radial component to the forces associated with the event.
		Several factors complicate this evaluation: the larger eruption of 22 May covered essentially the same area as was affected on 19 May; the 19 May pyroclastic deposits were relatively thin and were immediately covered by a volumetrically larger lahar; and all the deposits have been subjected to 70 years of erosion and modification.

	Eruption on Io Rivals Largest in Solar System
		The 2001 Io eruption was very close to Surt, the site of a large eruption in 1979 that took place between the Voyager 1 and Voyager 2 flybys.
		BRIGHT ERUPTION ON IO The area covered by the Io lava is considerably larger than the entire cone of one of Earth's most active volcanoes, Etna in Italy, and far larger than Etna's most recent eruption in 1992.
		The Surt eruption is clearly many times more energetic than the other eruptions observed with the same AO system, eruptions observed by the Galileo, and the sample terrestrial eruptions.

	Summary of Pu`u`O`o - Kupaianaha Eruption, Kilauea Volcano, Hawai`i
		The Pu`u `O`o-Kupaianaha eruption of Kilauea, now in its twenty-third year and 55th eruptive episode, ranks as the most voluminous outpouring of lava on the volcano's east rift zone in the past five centuries.
		In 1986, the eruption migrated 3 km down the east rift zone to build a broad shield, Kupaianaha, which fed lava to the coast for the next 5.5 years.
		In July 1986, the vertical conduit of Pu`u `O`o ruptured and the eruption shifted to a new vent, Kupaianaha, 3 km northeast of Pu`u `O`o.

		Such eruptions would be able to cause severe cooling of global temperatures for many years afterwards because of the huge volumes of sulfur and ash erupted.
		In February 2001, the largest recorded volcanic eruptions in the solar system occurred on Io Europa, the smallest of Jupiter's Galilean moons, also appears to have an active volcanic system, except that its volcanic activity is entirely in the form of water, which freezes into ice on the frigid surface.
		Several eruptions during the past century have caused a decline in the average temperature at the Earth's surface of up to half a degree (Fahrenheit scale) for periods of one to three years.

	Submarine volcanic eruptions
		This eruption was the first to be detected in real time as it was happening by the US Navy's SOSUS hydrophone network and the first to be responded to within weeks of the event.
		After this eruption, evidence was found that two other recent eruptions had occured on this segment between 1981 and 1991, based on repeated bathymetric surveys and seafloor mapping.
		It was the first eruption in which the hydrothermal event plume that was released with the eruption was tracked for months after the event.

	The Minoan Eruption
		The eruption was followed by collapse of the magma chamber that enlarged an existing caldera.
		The height of the plinian eruption column is estimated 36-39 km (Pyle, 1990).
		The first phase of the eruption is a typical pumice fall-out deposit from an estimated 36 km high eruption column.

	National Geographic: Eye in the Sky--Volcanoes (Site not responding. Last check: )
		Watching a volcanic eruption is as close as any human is likely to come to seeing the titanic forces that are at work in the interior of the planet.
		Sometimes the eruption is sudden and violent, as was the case at Mount St. Helens in southwestern Washington State in 1980, and at the Philippines’ Mount Pinatubo in 1991.
		Flows are high-speed avalanches of hot ash, rock fragments, and gas moving down the sides of a volcano during explosive eruptions, or when the steep edge of a dome breaks apart and collapses.

	Methane gas. Kivu lake
		The eruption of 25 x 106 m3 of magma formed a complex lava flow filed which ultimately fed two main flows that destroyed about 15% of the large town of Goma.
		The eruption that destroyed the homes of 120 000 people and caused between 70 and 100 victims was accompanied by unprecedented levels of felt high frequency seismicity of volcanic and tectonic origin.
		As detected by sudden major rise in the lake level, this eruption was also remarkably associated with perhaps up to 0,6-1 m of ground subsidence in the Goma area along the axis of the rift and thus aligned with the newly formed fractures.

	SEA LICE or Seabathers Eruption
		Outbreaks of seabather's eruption appear to be caused by shifts in South Florida's currents, with the highest incidence of cases in such areas as Palm Beach County and Northern Broward County, where the Gulf Stream passes closest to shore.
		Lesions associated with seabather's eruption have ranged from a barely discernible macular rash in those with no history of previous exposure to the largely typical maculopapular and occasionally vesicular eruption noted by most.
		The key to the diagnosis of seabather's eruption is a history of ocean exposure followed by the development of a dermatitis within 24 hours of exposure.

		Current eruption information for those visiting Hawai`i Volcanoes National Park can be obtained from the National Park Service at 808-985-6000 or at their web site: Hawai`i Volcanoes National Park.
		A number of additional bench collapses, brief eruption hiatuses and surface flow breakout episodes have also occurred, as well as a short period of enhance lava-lake activity at the crater in May 1998 that did not affect the overall effusion rate at the ocean entries.
		There was a brief hiatus in eruptive activity during a new intrusion of magma on the East Rift Zone, closer to the Kilauea caldera (Sept 1999) but activity resumed a week and a half later with spectacular surface flows, that made it to the sea by December of that year.

	Lassen Volcanic National Park - The Eruption of Lassen Peak (U.S. National Park Service)
		On May 22, 1915, an explosive eruption at Lassen Peak, the southernmost active volcano in the Cascade Range, devastated nearby areas and rained volcanic ash as far away as 200 miles to the east.
		This explosion was the most powerful in a 1914-17 series of eruptions that were the last to occur in the Cascades before the 1980 eruption of Mt. St.
		The most recent eruptions in the Lassen area were the relatively small events that The Chaos Crags, a group of six lava domes, was formed about 1,100 years ago in the latest large eruptions to occur in the area of occurred at Lassen Peak between 1914 and 1917.
