Mud Volcano Island Rises From Sea After Pakistani Earthquake
2013-09-26 14:22:20

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful earthquake that struck the southwestern province of Baluchistan, Pakistan Tuesday afternoon, killing hundreds of people, has given rise to a new island off the coast of the country's Gwadar Port. The island, which rises to more than 60 feet above sea level, received its first visits yesterday from local residents wanting to explore the small muddy, rocky landmass. As locals surveyed the new islet, it became evident that...

New Sourcing Technique Detects Obsidian In Seconds
2013-09-10 09:27:02

April Flowers for redOrbit.com - Your Universe Online Obsidian is a naturally occurring volcanic glass with a smooth, hard surface. It is far sharper than a surgical scalpel when fractured, making the glass a highly desirable raw material for crafting stone tools for almost all of human history. Found in East Africa, the earliest obsidian tools are nearly two million years old, and today, doctors still use obsidian scalpels in specialized medical procedures. The chemical composition of...

Newly Discovered Seismic Waves Reveal Earth's Volcanic Hotspots
2013-09-06 08:40:14

April Flowers for redOrbit.com - Your Universe Online A previously unknown channel of slow-moving seismic waves in the Earth’s mantle has been discovered by a team of scientists from the University of California, Berkeley and the University of Maryland. These waves help to explain "hotspot volcanoes" that give birth to island chains such as Hawaii and Tahiti. The findings of this study have been published in Science Express. Hotspot volcanoes form in the middle of tectonic plates,...

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...

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...

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...

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...

Mount Price
2014-08-19 10:51:33

Mount Price is a stratovolcano that is located in British Columbia, Canada. It is part of the Garibaldi Ranges and reaches an elevation of 6,732 feet, rising above the lake at its western side and the land and other volcanos surrounding it. In the past, this volcano has been known by many names including Red Mountain, Fissile Peak, and Clinker Mountain. It and many other volcanos are protected within the Garibaldi Provincial Park, which also features rich habitats with abundant wildlife....

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...

Socompa
2014-08-19 10:02:27

Socompa is a complex stratovolcano that can be found at the border of Chile and Argentina, reaching an elevation of 19,852 feet. This volcano is best known for its avalanche debris deposit, which have formed the Monturaqui Basin on its west side, the most noted example of this type of deposit in the world. It is a difficult volcano to visit, taking at least a day by vehicle traveling from the north or the west. Socompa is also known for the microbial ecosystems that occur near grasses at its...

Mount Erebus
2014-08-19 09:49:48

Mount Erebus is an active volcano that can be found on Ross Island in Antarctica. It is the second largest volcano in Antarctica, reaching a height of 12,448 feet. Sir James Clark Ross discovered it in 1841 in mid-eruption and named it and another volcano Mount Erebus and Mount Terror, after two of his ships. The first people to climb the volcano and reach its summit were part of Sir Ernest Shackleton's party, including Professor Edgeworth David, Jameson Adams, and Dr. Eric Marshall. Mount...
