On Oct. 9 an underwater volcano started to emerge in waters off El Hierro Island in the Canaries, Spain. Researchers of the Spanish Institute of Oceanography (IEO, Ministry of Science and Innovation) only needed 15 days to map its formation in high resolution. The volcanic cone has reached a height of 100 m and the lava tongue flows down its side, even though its activity has slowed down in the past few days. "This is probably the first time that such a young underwater volcano has been...

Chilean Volcano Could Have Major Eruption In Hours Or Days
2011-10-28 11:41:59

A volcano in Chile has released three columns of steam and ash that combined into a cloud of over 3 miles high on Friday. Officials in the country evacuated 119 people from the Hudson Volcano area, as other nearby residents prepared to flee due to melting snow and ice becoming a flood issue. Chile's national geology service said that the steam and ash was coming from three craters, ranging from 650 feet to 1,600 feet wide.  The service said that a major eruption could occur...

Image 1 - Fiery Volcano Give Researchers A Geologic Glimpse Into Land That Time Forgot
2011-10-20 09:31:50

[ Watch the Video ] The first scientists to witness exploding rock and molten lava from a deep sea volcano, seen during a 2009 expedition, report that the eruption was near a tear in the Earth's crust that is mimicking the birth of a subduction zone. Scientists on the expedition collected boninite, a rare, chemically distinct lava that accompanies the formation of Earth's subduction zones. Nobody has ever collected fresh boninite and scientists never had the opportunity to monitor...

Geologists Assess Deep Impacts Of Near-Earth Object Strikes
2011-10-18 08:03:44

Volcanologists from the Universities of Leicester and Durham have forensically reconstructed the impact of a meteorite on Earth and how debris was hurled from the crater to devastate the surrounding region. New research by Mike Branney, of the University of Leicester's Department of Geology, and Richard Brown, University of Durham, shows that some aspects of giant meteorite impacts onto Earth may mimic the behavior of large volcanic eruptions. Meteorite impacts are more common than is...

Another Icelandic Volcano Threatening Eruption
2011-10-16 04:42:55

An Icelandic volcano, dubbed by Daily Mirror reporter Mike Swain as "one of the most feared volcanoes in the world," could be close to a major eruption that would "dwarf" those originating from the nearby Eyjafjallajokull last year. In 2010, the Eyjafjallajokull eruptions created an ash cloud which left planes grounded, stranded travelers, and ultimately cost the European economy more than $1.5 billion. Even so, that eruption was classified as a minor one. Katla, the volcano currently...

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...

Image 1 - Mercury Has Widespread Flood Volcanism
2011-09-29 13:23:32

NASA announced on Thursday that its MESSENGER spacecraft has found new evidence that flood volcanism has been widespread on Mercury. New data from the spacecraft reveals that 6 percent of Mercury's total surface is covered by volcanic plains. "Analysis of the size of buried ℠ghost' craters in these deposits shows that the lavas are locally as thick as 2 kilometers" (or 1.2 miles), James Head of Brown University, the lead author of one of the reports published in Science, said in a...

Mount Nyiragongo
2014-08-28 11:22:30

Mount Nyiragongo is an active stratovolcano that is located in the Democratic Republic of the Congo. This volcano is part of the Virunga Mountains and is located in Virunga National Park. It reaches an elevation of 11,385 feet and has a crater that reaches 1.2 miles in width. This crater typically holds a lava lake that has varied between 2,000 and 10,660 feet in depth. It is not known how long this volcano has been active, but at least 34 eruptions have been recorded since 1882. Mount...

Chaitén
2014-08-28 10:38:21

Chaitén is a volcanic caldera that is located in southern Chile that reaches an elevation of 3,681 feet. It is thought that this volcano once held a rhyolite obsidian lava dome that reached 3,156 in height, but this was destroyed after its most recent eruption in 2008. In the past, this volcano has released grey obsidian, which was used by pre-Columbian cultures to make many objects, some of which have been found 250 miles away from the volcano. Chaitén experienced the beginning of a new...

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...

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...
