Two Alaskan Volcanoes Release More Energy, Stronger Eruptions Ongoing
2013-06-26 09:20:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Two of three active Alaskan volcanoes have shown a sizeable increase in activity since first erupting weeks ago, according to the Alaska Volcano Observatory (AVO). AVO warned the Pavlof and Veniaminof volcanoes could become even more active in the future. For now, both volcanoes have been spewing lava and ash into the atmosphere, with at least one of the two peaks disrupting local air traffic. Pavlof, an 8,000-foot,...

Each of the six new papers published in Geosphere on 13 June address geoscience compiled in specially themed issues: CRevolution 2: Origin and Evolution of the Colorado River System II; The 36—18 Ma southern Great Basin, USA, ignimbrite province and flareup: Swarms of subduction-related supervolcanoes; New Developments in Grenville Geology; and Origin and Evolution of the Sierra Nevada and Walker Lane. Abstracts for these and other Geosphere papers are available at...

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...

Humans Left Africa Later Than Thought
2013-06-12 08:51:11

redOrbit Staff & Wire Reports - Your Universe Online Modern humans did not leave Africa prior to the massive eruption of Sumatra´s volcano Mount Toba 74,000 years ago, according to a new study appearing in the journal Proceedings of the National Academy of Sciences. Rather, Professor Martin Richards of the University of Huddersfield and colleagues have concluded that genetic evidence supports the belief that they departed for Asia approximately 60,000 years ago. Their findings...

Evacuations Ordered As Chilean Volcano Increases In Activity
2013-05-28 05:59:29

Lawrence LeBlond for redOrbit.com - Your Universe Online Officials in Chile and Argentina issue a red alert to citizens living around the Copahue volcano, which sits on the border of both countries. Monday´s red alert, which is the highest level, also calls for the evacuation of nearly 3,000 people as activity increases on the mountaintop. Andres Chadwick, Chile´s Interior and Security Minister, said the increased activity could lead to an eruption, leading officials to begin...

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...

Volcanic Activity Increases On Alaska's Mount Pavlof
2013-05-20 07:33:36

Lawrence LeBlond for redOrbit.com - Your Universe Online Alaska´s Pavlof Volcano, which roared back to life on May 13, continues to send ash and steam nearly 20,000 feet into the air, just below the threshold that experts deem becomes a threat to air traffic in the region. Over the weekend, Pavlof also began spewing lava hundreds of feet into the air. The 8,262-foot-high Pavlof, which is located about 625 miles southeast of Anchorage along the Aleutian Islands, but still sits on...

Alaskan Volcano Pavlof Erupts
2013-05-17 12:51:06

Peter Suciu for redOrbit.com — Your Universe Online The Alaska Volcano Observatory has reported that the remote Pavlof Volcano continues to erupt and is now spewing lava, ash and steam 20,000 feet into the sky, which has been traveling southeast towards the Gulf of Alaska since Thursday. The Alaska Volcano Observatory (AVO) is a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the State of...

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...

Jabal al-Tair Island, known by many other names including Tair Island and Jebel Teir, is a volcanic island that is located in the Red Sea and is under the jurisdiction of Yemen. It reaches an elevation of 801 feet and is about 1.9 miles in length. The island is comprised of Jabal al-Tair, a stratovolcano that was considered extinct in 1982, although it erupted in 2007. In 1900, the British Admiralty described the volcano as having a steep, conical shape, making it a good landmark for ships...

Mauna Kea

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...

Zubair Group

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

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....
