Image 1 - Lava Flows On Mars Resembles Patterns On Earth
2012-04-27 03:52:42

Lee Rannals for RedOrbit.com New photos taken by the High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter show unique lava flows on Mars that resemble patterns seen on Earth. The lava flows reveal coiling spiral patterns that resemble snail or nautilus shells, according to research published in the scientific journal Science on Friday. On Earth, lava coils can be found on the Big Island of Hawaii, mainly on the surface of ropey pahoehoe lava...

Volcanic Activity In Alaska Heats Up
2012-02-20 11:16:06

Several volcanoes in our northernmost state of Alaska are showing increased signs of activity, and scientists are keeping a wary eye on them both, reports Yareth Rosen for Reuters. Kanaga Volcano, located near the port city of Adak, experienced a tremor Saturday morning followed by more seismic activity for about an hour, said the Alaska Volcano Observatory. This activity follows more of the same at Mount Cleveland, which threatens to make life troubling for Alaskans. Last erupting in...

Image 1 - 'Honeycombs' And Hexacopters Help Tell Story Of Mars
2012-02-18 06:22:14

In a rough-and-tumble wonderland of plunging canyons and towering buttes, some of the still-raw bluffs are lined with soaring, six-sided stone columns so orderly and trim, they could almost pass as relics of a colossal temple. The secret of how these columns, packed in edge to edge, formed en masse from a sea of molten rock is encrypted in details as tiny as the cracks running across their faces. To add to this mystery's allure, decoding it might do more than reveal the life story of some...

Lava Formations In Western US Linked To Tear In Giant Slab Of Earth
2012-02-17 04:04:00

Scripps scientists propose mass melting as new force behind volcanic activity in Columbia River region Like a stream of air shooting out of an airplane's broken window to relieve cabin pressure, scientists at Scripps Institution of Oceanography at UC San Diego say lava formations in eastern Oregon are the result of an outpouring of magma forced out of a breach in a massive slab of Earth. Their new mechanism explaining how such a large volume of magma was generated is published in the Feb....

Warning Level For Alaskan Volcano Raised
2012-02-01 15:22:52

The Alaska Volcano Observatory raised a warning level for a remote Alaskan volcano on Tuesday, indicating a possible eruption. The center elevated the alert status for Cleveland Volcano after a new lava dome was spotted in the summit crater.  Officials said the dome was about 130 feet in diameter as of Monday. The volcano is a 5,675-foot peak on an uninhabited island, 940 miles southwest of Anchorage, Alaska. Authorities say sudden eruptions could occur at any time, and ash...

Image 1 - NASA Radar To Study Hawaii's Most Active Volcano
2012-01-10 10:28:43

An airborne radar developed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., has returned to Hawaii to continue its study of Kilauea volcano, Hawaii's current most active volcano. The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, mounted in a pod under NASA's G-III research aircraft from NASA's Dryden Flight Research Center, Edwards, Calif., returned to Hawaii's Big Island on Jan. 7. The one-week airborne campaign will help scientists better understand processes...

Satellite imagery is showing Alaska´s Cleveland Volcano spewing ash 15,000 feet into the air from uninhabited Chuginadak Island about 940 miles southwest of Anchorage, USA Today is reporting. “It´s not expected to cause a disruption to big international air carriers,” U.S. Geological Survey (USGS) scientist-in-charge John Power said, who went on to call the event a “small explosion”. Air carriers in the region are showing a bit more concern, “any...

Image 1 - Microbes In Lava Tube Live In Conditions Like Those On Mars
2011-12-16 08:48:18

A team of scientists from Oregon has collected microbes from ice within a lava tube in the Cascade Mountains and found that they thrive in cold, Mars-like conditions. The microbes tolerate temperatures near freezing and low levels of oxygen, and they can grow in the absence of organic food. Under these conditions their metabolism is driven by the oxidation of iron from olivine, a common volcanic mineral found in the rocks of the lava tube. These factors make the microbes capable of living...

Image 1 - Researchers Fingerprint Hawaiian Lava
2011-11-30 11:12:01

Lava fingerprinting reveals differences between Hawaii's twin volcanoes Hawaii's main volcano chains--the Loa and Kea trends--have distinct sources of magma and unique plumbing systems connecting them to the Earth´s deep mantle, according to UBC research published this week in Nature Geoscience, in conjunction with researchers at the universities of Hawaii and Massachusetts. This study is the first to conclusively relate geochemical differences in surface lava rocks from both...

Undersea Volcano Forming New Canary Island
2011-11-12 06:25:39

A new Canary Island is rising to the surface before our very eyes, and the first images of the infant volcano that is slowly coming up to the surface in the Spanish archipelago emerged on Friday. According to the Daily Mail, "Magma off the Canary Island of El Hierro has been spewing 20 meters high as the sea boils with a smell of sulfur“¦ As it grows and gets closer to the surface, more and more debris such as stones start to shoot out of the volcano which, until now, has only...

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...

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....

Eldfell
2014-04-08 12:54:37

Eldfell is an active stratovolcano that is located in Iceland on the island of Heimaey, in the Vestmannaeyjar archipelago. It reaches an elevation of 656 feet and was created during a volcanic eruption on the east side of the island in 1973. Its name means Mountain of Fire in the Icelandic language. Iceland is an area with a high frequency of volcanic activity because it is located on top of the Iceland hotspot and beside the Mid-Atlantic Ridge. So many eruptions occur here that it is thought...

Volcanology
2014-01-12 00:00:00

Volcanology is the study of volcanoes, magma, lava, and related geological, geochemical, and geophysical phenomena. The term volcanology comes from the Latin word Vulcan. Vulcan is the ancient Roman god of fire. A volcanologist is a person who studies the creation of volcanoes, and their current and historic eruptions. Volcanologists frequently visit volcanoes, particularly active ones, to observe volcanic eruptions, collect eruptive products including samples of tephra, lava, and rock....
