Study Shows Extrusive Volcanism Formed Hawaiian Islands
2013-10-07 09:17:25

University of Hawaii ‑ SOEST A recent study by researchers at the University of Hawaii – Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) and the University of Rhode Island (URI) changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought. Before this work, most scientists...

Supervolcanic Ash Can Transform Into Lava Miles Away From Eruption
2013-08-28 06:33:27

Lawrence LeBlond for redOrbit.com - Your Universe Online New research has taken a closer look at how ash produced from supervolcanoes can turn back into lava once it falls back to Earth. Supervolcanoes, such as the Yellowstone caldera, are capable of producing eruptions thousands of times stronger than normal volcanoes. Such a massive eruption can produce an ash cloud that is so hot it has the ability to re-form into lava once it hits the ground much farther away. This evidence was...

Scientists Uncover Link Between Lavas Erupting On Sea Floor And Deep-carbon Cycle
2013-05-03 08:05:27

Smithsonian Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth. The team's research was published May 2 in Science Express. Elizabeth Cottrell, lead author and research geologist at the Smithsonian's...

New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Brett Smith for redOrbit.com - Your Universe Online Neither explosive nor effusive–there´s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience. According to the U.K. and New Zealand scientists who authored the description, volcanic pumice produced by the Macauley volcano in the southwest Pacific is the result of a previously unarticulated type of eruption. “By documenting the shape and density of bubbles in pumices...

Parking Lot Lava Flows
2012-08-21 08:07:30

April Flowers for redOrbit.com - Your Universe Online How often have you wished you could safely see a lava flow, like the one that destroyed Pompeii?  Did you ever wish you could see it in Syracuse, New York? Professors, students, visiting volcanologists and passing spectators are now seeing lava flows in a campus parking lot at Syracuse University and have been since January 2010. The Syracuse University Lava Project has created a unique blending of science, art, and education...

La Garrotxa: Researchers Pinpoint Youngest Volcanic Area In Spain
2012-07-24 12:52:30

Brett Smith for redOrbit.com - Your Universe Online Although volcanic scientists are able to approximate the age of lava flows, determining the exact timing of each of a volcano´s eruptions has proved difficult in the past. A joint research team from the Universitat Autònoma de Barcelona, University of Girona, the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and other organizations has looked to establish a chronology of eruptions in the...

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...

Guatemala On Alert After Fuego Spews Lava And Ash
2012-05-21 07:04:36

Guatemalan authorities raised an alert after the country´s most active volcano, Fuego, began spewing lava and columns of ash into the air at around 2:45 a.m. (0745 GMT) on May 19. Fuego, which overlooks the tourist hotspot of Antigua, shot ash 16,400 feet into the air and spewed lava 1,300 feet high and up to 3,280 feet long, according to a statement by Guatemala´s National Seismology, Vulcanology, Meteorology and Hydrology Institute. The disaster agency´s David de Leon...

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...

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....

Rhyolite is an igneous, volcanic (extrusive) rock, of felsic composition, with aphanitic to porphyritic texture. Mineral assembly is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2). Biotite and pyroxene are common accessory minerals. Rhyolite can be considered as the extrusive equivalent to the plutonic granite rock. Due to their high content of silica, rhyolite form highly viscous lavas. They can also occur as breccias or in volcanic necks and dikes. Like obsidian,...
