Biggest Volcano On Earth At Bottom Of Pacific Ocean
2013-09-05 16:59:25

[ Watch the Video: Pacific Ocean Home To World's Largest Volcano ] Brett Smith for redOrbit.com – Your Universe Online Researchers, led by University of Houston professor William Sager, have been able to confirm the existence of the world’s largest single volcano at the bottom of the Pacific Ocean, according to an upcoming report in Nature Geoscience. Called Tamu Massif, the volcano covers an area about the size of the British Isles. Without a similar volcano here on Earth,...

Predicting Activity Inside And Out For Peruvian Volcanoes
2013-09-03 04:56:24

April Flowers for redOrbit.com - Your Universe Online Underneath volcanoes, water and fire coexist to generate “hydrothermal” systems. These systems are complex “steam engines” that produce white smoke – fumaroles – sometimes observed at the surface. A new study, led by the Institut de Recherche pour le Developpement (IRD), demonstrates why these hydrothermal reservoirs are not always found under volcanic peaks. The volcanologists conducted their study at the Ticsani and...

Cassini Data Reveals Unexpected Features In Titan’s Icy Outer Shell
2013-08-28 15:52:50

[ Watch the Video: A Titan View from Huygens ] Lee Rannals for redOrbit.com - Your Universe Online Cassini, a joint NASA/ESA/ASI orbiter, arrived at Saturn a little over nine years and has been observing the ringed planet and its moons ever since. The latest data from the spacecraft shows that the planet's largest moon, Titan, has some unexpected features. A new study published in the journal Nature reveals that Titan's rigid outer ice shell has some features quite different from any...

Helmholtz Association Real time observation of shear waves on the Earth's surface, first direct observation of subducting continental crust during the collision of two continents Earthquake damage to buildings is mainly due to the existing shear waves which transfer their energy during an earthquake to the houses. These shear waves are significantly influenced by the underground and the topography of the surrounding area. Detailed knowledge of the landform and the near-surface...

Unexpected Plume Challenges Iron Estimates
2013-08-20 08:47:27

April Flowers for redOrbit.com - Your Universe Online A vast plume of iron and other micronutrients more than 620 miles long has been discovered billowing from hydrothermal vents in the South Atlantic Ocean. Teams of scientists from Woods Hole Oceanographic Institute (WHOI) and the University of Liverpool, UK say their findings, published in an upcoming issue of Nature Geoscience, call into question past estimates of iron abundances and may challenge researchers’ previous assumptions...

Eruptions Not Always Imminent From Slow Magma
2013-08-20 04:41:19

April Flowers for redOrbit.com - Your Universe Online A new modeling study from the University of Washington reveals reservoirs of silica-rich magma of the sort that causes the most explosive volcanic eruptions can persist for hundreds of thousands of years in the Earth’s upper crust without triggering an eruption. In other words, regions such as Yellowstone National Park, known to have experienced a massive volcanic eruption in the past, could have a large pool of magma festering...

Japanese Volcano Produces Largest Eruption In Nearly A Century
2013-08-19 07:06:54

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the world’s most active volcanoes showed its ugly side this weekend, erupting and producing an ash cloud that spread out across one southern Japanese city. Sakurajima, a volcano that sits in the background of the southern Japanese city of Kagoshima and is known for producing hundreds of small explosions per year, erupted Sunday in one of the volcano’s largest explosions in decades and perhaps the largest since an...

Improved Eruption Forecasts May Come Via Costa Rican Volcano Study
2013-08-01 07:54:55

April Flowers for redOrbit.com - Your Universe Online Compared to the geologic timescales most volcanoes operate on, Costa Rica's Irazu has something of a short fuse. A new study, led by Columbia University's Lamont-Doherty Earth Observatory, suggests the 1960's eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought. The study, published in Nature, is...

Scientists at the University of Bonn simulate that seismic waves can be focused like in a parabolic reflector In 2006 the island of Java, Indonesia was struck by a devastating earthquake followed by the onset of a mud eruption to the east, flooding villages over several square kilometers and that continues to erupt today. Until now, researchers believed the earthquake was too far from the mud volcano to trigger the eruption. Geophysicists at the University of Bonn, Germany and ETH Zurich,...

Earth's Origins May Be Explained Through Mantle's 'Hidden Flux'
2013-07-17 14:46:32

Brett Smith for redOrbit.com - Your Universe Online One of the more popular theories surrounding the formation of the planets involves the countless collisions of smaller objects in orbit around the sun 4.5 billion years ago. However, proponents of that theory are missing one thing: the Earth's chemical composition is distinctly different from the meteors that are currently striking the planet. Scientists have found that the lead-uranium ratio of meteors is much different than that of...

Villarrica
2014-08-19 11:03:54

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...

Hoodoo Mountain
2014-08-19 10:23:50

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...

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....

This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
