The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do. But now, geochemists from Brown University have found a mineral structure with which the nobles deign to fraternize. Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...

Volcano Monitoring Program Searches Iceland For Early Signs Of Eruptions
2013-05-23 13:49:01

Lee Rannals for redOrbit.com — Your Universe Online A new collaborative project called FutureVolc is aimed at trying to improve monitoring of Iceland's volcanoes. FutureVolc started October 1, 2012 and is funded by the Environmental/FP7 program of the European Commission. The project says its main objectives are to establish an integrated volcano monitoring system through European collaboration, develop new methods to evaluate volcanic crises, increase scientific understanding of...

NASA Studies Volcanoes From Space
2013-05-07 14:59:27

Brett Smith for redOrbit.com - Your Universe Online By using both optical and thermal sensing instruments onboard the Landsat Data Continuity Mission (LDCM) satellite, NASA scientists were able to create a comprehensive image of the Pacific´s Paluweh volcano in mid-eruption. Taken on April 29, 2013, the images show the island volcano with a plume of ash appearing to drift northwest and over Indonesia's Flores Sea. While the satellite's Operational Land Imager detected the white...

2013-05-06 08:26:59

Lawrence LeBlond for redOrbit.com - Your Universe Online An Alaskan volcano roared to life on Saturday spewing a cloud of ash, steam and gas into the atmosphere, potentially disrupting a major air traffic route, according to scientists. The Cleveland Volcano, which sits at the western end of Chuginadak Island (part of the Aleutian Islands), erupted in at least three low-level explosions that were not severe enough to cause significant threats to air travel, but did force federal...

Tuya Volcanoes Reveal Glacial, Palaeo-climate Secrets
2013-04-30 10:56:06

University of British Columbia Detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research by University of British Columbia geoscientists....

Volcanic Eruption Forecasting Improvements Needed
2013-04-30 05:24:43

[ Watch the Video: What is a Volcano? ] April Flowers for redOrbit.com - Your Universe Online Recognizing well-established patterns of pre-eruption unrest in monitoring data is vital in volcanic eruption forecasting. To develop better monitoring procedures, however, understanding volcanic eruptions that deviate from these patterns is crucial as well. Diana Roman from the Carnegie Institution for Science led a research team that retrospectively documented and analyzed the period...

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

Lawrence LeBlond for redOrbit.com - Your Universe Online One of Iceland´s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak. Geologists at the Icelandic Met Office reported unusual seismic activity on the mountain over the past two to three weeks, but said there was no sign that an eruption was imminent. The...

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

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....

Askja
2014-04-09 16:13:20

Askja is an active stratovolcano that is located in the isolated central highlands in Iceland. It reaches an elevation of 4,974 feet and its name literally means caldera, or box, in the Icelandic language. The area can only be reached during a period of a few months and because it located in the rain shadow of the Vatnajökull glacier to the northeast, it only receives 17.7 inches of rain per year. One of Askja’s smaller craters holds a lake known as Öskjuvatn, which is often frozen over...

Santa María Volcano
2014-04-09 10:58:40

Santa María Volcano is an active stratovolcano that is located in Guatemala and is part of the Sierra Madre, a string of volcanoes that stretches across the western side of Guatemala. The volcanoes in this string were formed by subduction activity, when the Cocos Plate moved under the Caribbean Plate. An eruption in 1902 produced a crater that now holds a lava dome known as Santiaguito, which was created during another eruption in 1922. These domes hold active vents and in 1929, part of the...
