Impact Crater On Mars Could Actually Be Supervolcano
2013-10-23 09:11:16

Lawrence LeBlond for redOrbit.com - Your Universe Online In a first-of-its-kind discovery, scientists from NASA and the Planetary Science Institute in Tucson, Arizona have identified what could be a supervolcano on a planet, other than Earth, in our Solar System. The supervolcano in question was discovered on Mars and was previously classified as an impact crater. But after further analysis of the area, scientists believe the basin is actually the remnant landscape of an ancient...

Antarctic Volcano Seamounts Present Many Riddles To Volcanologists
2013-10-18 05:20:11

April Flowers for redOrbit.com - Your Universe Online When you think of the Antarctic, images of snow, ice and glaciers are the usual associations. We forget that it is also a region of fire, dotted with volcanoes on the mainland and the surrounding islands. Some of these volcanoes are extinct and some are still active, such as the Marie Byrd Seamounts in the Amundsen Sea. Today, their summit plateaus are at depths of 7,800 - 5,200 feet, making them difficult to reach with conventional...

Scientists Look At Supervolcano Life Cycle In Whole New Way
2013-10-11 14:49:13

Lee Rannals for redOrbit.com - Your Universe Online Scientists say they've discovered a new way to look at the life cycle of a supervolcano at a Yellowstone hotspot. University of Oregon researchers said that crystals of zircon from the Snake River Plain helped to solidify evidence of "recycled" super-volcanic magma chambers. This Yellowstone hotspot creates a conveyor belt style of volcanism because of the southwest migration of the North American plate at about 0.8 to 1.6 inches...

Iceland's Basalt Pillars Formed By Slow Lava And Water
2013-10-09 15:55:39

Brett Smith for redOrbit.com - Your Universe Online Icelandic folk legend has it that the rocky pillars in the country’s Skaelingar Valley were projectiles fired into the ground by armies of warring trolls. However, a new study in Journal of Volcanology and Geothermal Research indicates that these hollow pillars of basalt were formed by a very slow lava flow oozing from Iceland's volcanoes and interacting with water. The researchers’ conclusion is unusual because the mixing of water...

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...

First Ancient Mars Supervolcano
2013-10-02 14:00:10

[ Watch the Video: Supervolcano Found On Mars ] Lee Rannals for redOrbit.com - Your Universe Online In a report that appeared in the journal Nature this week, scientists say they have discovered a supervolcano on Mars for the first time. The scientists determined that a vast circular basin on the face of the Red Planet is actually the remains of an ancient supervolcano eruption. To reach this conclusion, the team used images and topograhic data from NASA's Mars Odyssey, Mars Global...

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...

Study Finds Human Activity Affects Vertical Structure Of Atmospheric Temperature
2013-09-17 13:05:39

Lawrence Livermore National Laboratory Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multi-model archive of simulations. "Human activity has very different effects on the temperature of the...

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,...

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...

Galeras
2014-08-28 10:56:28

Galeras is a stratovolcano that is located in Nariño, a Colombian controlled territory. This volcano, which reaches a height of 14,029 feet, is highly active and the most active volcano in Colombia. It primarily contains andesite and holds two calderas that were created by eruptions in the past 560,000 years. Although it is shaped like a horseshoe, eruptions have caused a cone shaped structure to build up in one of the calderas. It was labeled a Decade Volcano in 1991, despite its recent...

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....
