Small Volcanoes Also Affect Climate
2012-07-06 10:13:36

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of researchers have found that even small volcanic eruptions can lead to a cooler climate if they coincide with weather systems such as monsoons, which boost aerosols produced by eruptions high into the atmosphere affecting global temperatures. The research, led by scientists from the University of Saskatchewan in Canada, suggests that the previously held belief that only massively energetic eruptions could...

Smaller Volcanoes Could Cool Climate According To Satellite Research
2012-07-05 16:33:57

A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science. Adam Bourassa, from the U of S Institute of Space and Atmospheric Studies, led the research. He explains that until now it was thought that a massively energetic eruption was...

Aleutian Island Volcano Erupts
2012-06-21 06:56:08

Lee Rannals for redOrbit.com If the Cleveland Volcano had any neighbors, then it decided to wake them up on Tuesday when the volcano shot off a thin cloud of ash several miles into the sky. The Alaska Volcano Observatory reported that the 5,676-foot volcano on the uninhabited island had an explosive eruption at about 2:05 p.m. on Tuesday. A pilot flying in the area estimated the ash cloud rose to 35,000 feet above sea level, according to the observatory. However, Stephanie...

New Geology articles posted online ahead of print June 15 Orange-like rocks in Utah with iron-oxide rinds and fossilized bacteria inside that are believed to have eaten the interior rock material, plus noted similarities to "bacterial meal" ingredients and rock types on Mars; fine-tuning the prediction of volcanic hazards and warning systems for both high population zones and at Tristan da Cunha, home to the most remote population on Earth; news from SAFOD; and discovery in Germany of the...

Potential Eruption In Iceland Could Pump Acid Into European Airspace
2012-06-12 15:11:11

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava” eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and...

Warning Signs Of The 2011 Axial Seamount Eruption
2012-06-11 02:53:32

A team of scientists that last year created waves by correctly forecasting the 2011 eruption of Axial Seamount years in advance now says that the undersea volcano located some 250 miles off the Oregon coast gave off clear signals just hours before its impending eruption. The researchers´ documentation of inflation of the undersea volcano from gradual magma intrusion over a period of years led to the long-term eruption forecast. But new analyses using data from underwater hydrophones...

Volcanic Super-Eruptions A Quicker Threat Than Previously Thought
2012-05-31 05:03:53

Lee Rannals for RedOrbit.com Volcanoes capable of super-eruptions that could be catastrophic for civilizations have short fuses, according to new research conducted at Vanderbilt University. Super-eruptions are more than 100 times the size of ordinary volcanic eruptions like Mount St. Helens. These types of eruptions spew out super-heated gas, ash and rock, and are capable of leveling entire continents. Researchers say that there is evidence of one super-eruption that took place in...

Crystal Composition Could Predict Volcanic Eruptions
2012-05-26 05:03:51

By studying crystals formed in volcanic rock, experts may be able to predict an impending eruption up to a year in advance, researchers from the University of Bristol have discovered. According to a Thursday press release from the university, Dr. Kate Saunders and her colleagues used forensic-style chemical analysis to link seismic observations of a 1980 eruption at Mount St. Helens to the growth of crystals within the large underground pool of liquid rock beneath the volcano known as the...

Melting Mantle Linked To Great Oxygenation Event 2.5 Billion Years Ago
2012-05-25 04:38:16

Brett Smith for RedOrbit.com Oxygen-based life evolved on Earth because of geological events that occurred over 2.5 million years ago, according to Princeton University researchers who published a report this week in the online journal Nature. Based on geological evidence, scientists know that roughly 2.5 billion years ago, oxygen levels in the atmosphere exploded and eventually gave birth to our present atmosphere. This time period, dubbed the Great Oxygenation Event (GOE), appears to...

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
2014-04-10 10:08:46

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...
