U.S. scientists say they have used simulations to determine the atmosphere of an exoplanet discovered in February is hot enough to rain pebbles. Researchers at Washington University in St. Louis say their models show the exoplanet is close enough to its star that its day-face maintains a temperature of about 4,220 degrees Fahrenheit -- hot enough to vaporize rocks. The theoretical models suggest the planet has an atmosphere of the components of rock in gaseous form and lava or boiling oceans...

Hawaii's Kilauea volcano seems to be active again, with molten lava moving around 300 feet under the crater's floor. The growth of the Halemaumau crater corroborates scientists' certainty that the lava is near the summit, said Janet Babb, a geologist and spokeswoman at the U.S. Geological Survey's Hawaiian Volcano Observatory. Park rangers have started allowing the overlook at the Jaggar Museum to stay open later in the evening to have capacity for the larger numbers of visitors to see the...

U.S. and French scientists say they have discovered the origin of carbon-based lavas erupting from a Tanzanian volcano. The researchers, led by the University of New Mexico, analyzed gas samples collected from inside the active crater of Tanzania's Oldoinyo Lengai volcano -- the only volcano that is actively producing carbon-based lavas. The geochemical analyses revealed a very small degree of partial melting of minerals in the Earth's upper mantle is the source of the rare carbon-derived...

Two volcanoes near a major city in eastern Congo have begun showing evidence of intense volcanic activity - tremors, pools of lava and plumes of smoke - causing some residents flee the area, MSNBC reported. Scientists who visited the two volcanic peaks of Nyiragongo and Nyamulagira said on Thursday the volcanoes could be near eruption and would threaten Goma, a city with a population of more than half a million people. Dieudonne Wafula, the head of Goma's Volcanological Observatory, said the...

Carbon dioxide completely "disappears" into the atmosphere at all other volcanoes on Earth Science has unearthed the secret to what might have been alchemy at Oldoinyo Lengai volcano in Tanzania. There, in the ancient East African Rift at a place known to local Maasai people as the Mountain of God, Oldoinyo Lengai spews forth carbon dioxide-laden lavas called carbonatites. The carbonatites line the volcano's flanks like snowballs. Oldoinyo Lengai is the only place on Earth where carbonatites...

Science and aid agencies said that two volcanoes may erupt in heavily populated eastern Democratic Republic of Congo, where years of fighting have already forced a million people from their homes. Scientists in Goma have registered high levels of seismic activity in recent weeks, which is considered an early warning sign of an impending eruption, around the Nyiragongo and Nyamuragira volcanoes. "There is heavy activity around Nyiragongo, but it's more centered on Nyamuragira, around 8 miles...

Using radar images acquired by ESA satellites from 1992 to 2006, scientists have for the first time been able to monitor the long-term behavior of Mt. Etna, Europe's highest and most active volcano. This unprecedented time series of Synthetic Aperture Radar (SAR) observations from ESA's ERS-1, ERS-2 and Envisat satellites provided crucial information for understanding how the volcano's surface deformed during the rise, storage and eruption of magma. Changes in surface deformation, such as...

Nyiragongo, an active African volcano, possesses lava unlike any other in the world, which may point toward its source being a new mantle plume says a University of Rochester geochemist. The lava composition indicates that a mantle plume"”an upwelling of intense heat from near the core of the Earth"”may be bubbling to life beneath the soil of the Democratic Republic of the Congo. The findings are presented in the current issue of the journal Chemical Geology."This is the most...

The Kilauea volcano on the big island of Hawaii took a three-day break this week from its 26-year eruption. Scientists said that lava stopped flowing at what is known as the Thanksgiving Eve Breakout on Monday and started up again on Christmas Eve, the Honolulu Advertiser reported Friday. Jim Kauahikaua, head of the Hawaiian Volcano Observatory of the U.S. Geological Survey, said that interruptions have become more common, although they are usually shorter than three days, and that scientists...

NEW YORK, Dec. 19 /PRNewswire/ -- First it made calls, then it checked email and surfed the web, but now the once-humble mobile phone can be used as ... a lava lamp! Gotham Wave Games, a small technology company based in New York City, recently launched an application for the iPhone that turns the device into a realistic approximation of the groovy '60s tabletop icon. Going one step beyond the original item, the "iLava" program lets users interact with the virtual blobs of hot wax....

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

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,...
