Arsia Mons
2014-05-28 04:41:47

redOrbit Staff & Wire Reports - Your Universe Online As part of the ongoing search for potentially habitable regions of Mars, geologists from Brown University have pinpointed a volcano that was once encased in glacial ice which could have created large lakes of liquid water. According to the researchers, the Arsia Mons volcano would have created large lakes filled with liquid water after it erupted, making that area one of the most recent habitable environments discovered to date on...

Origins On The Behavior Of Hawaiian Volcanoes
2014-05-01 03:05:10

University of Hawaii ‑ SOEST Kīlauea volcano, on the Big Island of Hawai'i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in Kīlauea's eruption styles, a team including Bruce Houghton, the Gordon Macdonald Professor of Volcanology in Geology and Geophysics at the University of Hawai'i...

Magma Chamber Of Galapagos' Sierra Negra Volcano Imaged In 3D
2014-03-06 10:01:48

April Flowers for redOrbit.com - Your Universe Online Some of the most active volcanoes in the world can be found in the Galapagos Islands. These volcanoes are responsible for more than 50 eruptions in the last 200 years. Even with such activity, scientists knew far more about the history of finches, tortoises and iguanas on the islands than the volcanoes upon which these unusual fauna had evolved. A new study from the University of Rochester, published in the Journal of Geophysical...

Lava Floods Mars Ancient Plains
2014-03-06 09:30:21

ESA Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The images were acquired by ESA’s Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found. The lava flows seen in this image come from Arsia Mons, the southernmost volcano in the Tharsis complex, which lies around 1000 km to the northwest of...

Large Magma Chamber Sits Below World’s Most Active Volcano
2014-01-29 13:29:50

[ Watch the Video: What's Bubbling Below The Kilauea Volcano? ] Lee Rannals for redOrbit.com - Your Universe Online University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers have discovered a large magma chamber below the world’s most active volcano. The new discovery is the first geophysical observation that large magma chambers exist in the deeper parts of Kilauea. For the study, the team analyzed the seismic waves that travel through the volcano....

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...

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,...

ESA Images Mars Largest Volcano
2013-07-05 12:20:47

Brett Smith for redOrbit.com - Your Universe Online Recently released images from the European Space Agency's (ESA) Mars Express revealed new details of the largest known volcano in our solar system, Olympus Mons. The inactive Martian volcano rises to approximately 22,000 feet above the surrounding plain, which is more than twice the height of Earth's 10,000-foot high Mauna Kea volcano. Like Mauna Kea, Olympus Mons is a shield volcano, with gently sloping sides that extend outward in...

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...

Mauna Kea
2014-04-10 11:49:35

Mauna Kea is a dormant shield volcano that is located on the island of Hawaii and reaches an elevation of 13,803 feet. It is one of five volcanoes that comprise the island and is thought to be about one million years old. Mauna Kea, like all Hawaiian volcanoes, was created when the Pacific tectonic plate passed over a volcanic hotspot. The Hawaiian volcanoes, which extend over an area known as the Hawaiian Ridge – Emperor Seamount chain, have been well studied, but it is not known how the...

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....

Haleakalā
2014-04-09 16:28:16

Haleakalā, also known as the East Maui Volcano, is a possibly active shield volcano that is located in Hawaii and actually comprises 75 percent of the island of Maui. Its name means house of the sun in the Hawaiian language and local legend says that the crater was the home of the demigod Māui’s grandmother, who helped him to force the sun to move slowly over the course of the day in order to prolong it. This volcano reaches an elevation of 3,055 feet and it holds steep slopes and a few...

Kīlauea

Kīlauea is an active shield volcano that is located on the island of Hawaii and is located within Hawaii Volcanoes National Park. This volcano, which reaches an elevation of 4,091 feet, is one of five volcanoes that form the island and it is the most active. It is thought to be between 300,000 and 600,000 years old and is the second youngest of all the Hawaii volcanoes. It was formed when the Pacific tectonic plate moved over the Hawaiian hotspot and like other Hawaiian volcanoes, it began...
