Image 1 - Undersea Volcanic Eruptions Continue Near Canary Islands
2011-10-14 08:46:24

Two volcanic eruptions were confirmed on Wednesday near the Canary Islands, forcing at least 500 people to spend the night outside of their homes after precautionary evacuations were ordered by local authorities. These eruptions follow similar earth movement on Monday of the same week. “I confirm the existence of two points of volcanic eruption at El Hierro,” Laura Otero, a spokeswoman for the local authorities, told AFP. The first eruption occurred at a depth of 2,300...

Scientists Find Possible Trigger For Volcanic 'Super-eruptions'
2011-10-13 03:35:17

The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions. However, a new model presented this week by researchers at Oregon State University points to a combination of temperature influence and the geometrical configuration of the magma chamber as a potential cause for these super-eruptions. Results of the...

Tenerife Landscape Reveals Explosive Past
2011-10-03 04:51:52

Volcanologists from the University of Leicester have uncovered one of the world's best-preserved accessible examples of a monstrous landslide that followed a huge volcanic eruption on the Canarian island of Tenerife. Seven hundred and thirty-three thousand years ago, the southeast slopes of Tenerife collapsed into the sea, during the volcanic eruption. The onshore remains of this landslide have just been discovered amid the canyons and ravines of Tenerife's desert landscape by...

Scientists Concerned By Continued Eruptions At Alaskan Volcano
2011-09-18 04:41:53

  The two-month long, low-level eruptions occurring at a volcano in Alaska's Aleutian Islands have volcanologists worried that there could be a larger eruption forthcoming, Yereth Rosen of Reuters reported on Friday. The volcano causing concern is Cleveland Volcano (also known as Mount Cleveland), a 5,676-foot peak located less about 940 miles southwest of Anchorage. As previously reported here on RedOrbit, an eruption warning was issued by the Alaska Volcano Observatory in late...

Remote Alaska Volcano Resumes Dome Growth

  Mount Cleveland, a volcano sitting on the western half of Chuginidak Island 115 miles west of Dutch Harbor and 950 miles southwest of Anchorage, is reported to be on watch status with an aviation color code of orange, according to the Alaska Volcano Observatory (AVO). Anchorage Daily News reported in July that a lava dome was forming in the crater of the volcano and reached a width of 140 feet in diameter. But on August 30, it appeared that the lava dome had reached a maximum...

Iceland Keeps Eye On Katla Volcano After Tremors
2011-09-07 09:33:03

  Iceland´s Katla volcano has been the site of small but increasing earthquake activity but scientists said Tuesday there is no immediate concern that the increased seismic activity will trigger a dangerous eruption. Earthquakes around Katla are common, increases in cluster earthquakes are not, reports the Associated Press (AP). “It´s one of the most feared volcanos, so we´re closely monitoring it,” Pall Einarsson of the University of Iceland told AP's...

  In his new book, ℠Deep-Sky Companions: The Secret Deep,´ Stephen James O'Meara presents 109 new objects for stargazers to observe. The Secret Deep contains many exceptional objects, including a planetary nebula whose last thermal pulse produced a circumstellar shell similar to the one expected in the final days of our Sun's life; a piece of the only supernova remnant known visible to the unaided eye; the flattest galaxy known; the largest edge-on galaxy in the heavens;...

Mount Etna Begins 12th Eruption Of Year
2011-08-30 09:44:46

  Italy´s famed volcano Mt. Etna has erupted for the twelfth time this year, spewing lava and ash into the upper atmosphere, according to an Associated Press report. Italy´s Civil Protection Agency says the nation´s geophysics and volcanology institute on Monday registered increased explosive activity by Etna, eight days after the latest eruption began, spewing out a significant amount of ash in a southeast direction early in the day but that the eruption tapered off...

The 2010 ash cloud from Iceland's Eyjafjallajokull volcano that disrupted air travel in the UK and cost European businesses more than $2.6 billion was likely a once in a lifetime event, according to scientists, who have analyzed a record of past similar events stretching back into prehistory across northern Europe. Their analysis showed that past ash clouds like the one seen in 2010 occurred on an average of once every 56 years. A report of the findings has been published in the journal...

US scientists from Oregon and New York, who have been monitoring the Axial Seamount, an undersea volcano located 250 miles off the Oregon coast, said on Tuesday that they have successfully predicted an eruption for the first time. The team of scientists forecast the eruption beginning about five years ago, predicting the volcano, which last erupted in 1998, would erupt again sometime before 2014. This marks the first successful prediction of eruption of an undersea volcano. During an...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Zubair Group

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....

Askja
2014-04-09 16:13:20

Askja is an active stratovolcano that is located in the isolated central highlands in Iceland. It reaches an elevation of 4,974 feet and its name literally means caldera, or box, in the Icelandic language. The area can only be reached during a period of a few months and because it located in the rain shadow of the Vatnajökull glacier to the northeast, it only receives 17.7 inches of rain per year. One of Askja’s smaller craters holds a lake known as Öskjuvatn, which is often frozen over...

Santa María Volcano
2014-04-09 10:58:40

Santa María Volcano is an active stratovolcano that is located in Guatemala and is part of the Sierra Madre, a string of volcanoes that stretches across the western side of Guatemala. The volcanoes in this string were formed by subduction activity, when the Cocos Plate moved under the Caribbean Plate. An eruption in 1902 produced a crater that now holds a lava dome known as Santiaguito, which was created during another eruption in 1922. These domes hold active vents and in 1929, part of the...
