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...

Federal Budget Cuts Will Disrupt Critical Volcano Monitoring Services In Alaska
2013-05-15 08:24:13

Lawrence LeBlond for redOrbit.com - Your Universe Online More than a week after Alaska´s Cleveland volcano began erupting, sending ash clouds 15,000 feet into the air, another Alaskan mountaintop began rearing its ugly head. The Pavlof volcano, which sits about 350 miles northeast of Cleveland, showed signs on Monday that it was on the verge of eruption, based on increased seismic activity at the summit, according to Wired Magazine. Cleveland and Pavlof both sit in Alaska´s...

Mexico's Popocatepetl Volcano Increases Activity, Warnings Issued
2013-05-13 10:49:50

Lawrence LeBlond for redOrbit.com - Your Universe Online Authorities in Mexico have raised the alert level for towns in two central states and the capital after an increased amount of explosive activity has occurred at Popocatepetl volcano, Mexico´s second highest peak at 17,900 feet. The volcano, which sits about 50 miles southeast of the capital, began spewing steam and lava Saturday evening. Mexico´s National Disaster Prevention Center said an increase in activity was...

Scientists Uncover Link Between Lavas Erupting On Sea Floor And Deep-carbon Cycle
2013-05-03 08:05:27

Smithsonian Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth. The team's research was published May 2 in Science Express. Elizabeth Cottrell, lead author and research geologist at the Smithsonian's...

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...

Oceanic Volcanoes Reveal Signs Of Ancient Earthen Crust
2013-04-25 07:27:13

April Flowers for redOrbit.com - Your Universe Online For a long time now, scientists have been convinced that lava that has erupted from certain oceanic volcanoes contains material from the crust of early Earth, but decisive evidence has been elusive. A new study, published in the journal Nature, reveals that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Oceanic crust sinks below the Earth's mantle where two tectonic...

Yellowstone Volcano Debate: Both Sides May Be Right
2013-04-16 05:23:36

April Flowers for redOrbit.com - Your Universe Online The geologic formation of the supervolcano encompassing the Yellowstone National Park region has been the subject of much debate. A new study, led by the University of Rhode Island's Professor Christopher Kincaid, provides new evidence that may put an end to the debate by demonstrating both sides may be right. The international team of scientists used a state-of-the-art plate tectonic laboratory to show the volcanism in the...

Windows Into Europa's Icy Interior
2013-04-15 05:40:10

redOrbit Staff & Wire Reports - Your Universe Online By taking a second look at observations made more than a decade ago, NASA scientists have discovered regions that might give them the best look at the deep saltwater ocean beneath the icy shell of Jupiter´s moon Europa. The surface of this natural satellite exposes material originating both from the inside of the moon and from matter and energy coming from above, the US space agency explained in a statement on Friday. In...

Volcanic Activity Would Have Helped Mars Sustain Liquid Water
2013-04-09 10:17:31

Brett Smith for redOrbit.com - Your Universe Online A new study suggests that Earth´s atmosphere is largely the product of carbon dioxide gas moving from the mantle to the surface through volcanic activity; if similar activity were to happen on Mars — the planet would be able to sustain liquid water. According to the study, which appeared in the early online edition of Proceedings of the National Academy of Sciences (PNAS), greenhouse gases such as methane and carbon dioxide...

Geologists Say Earth Is Congested
2013-04-01 10:38:38

Brett Smith for redOrbit.com - Your Universe Online According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions. The Earth´s crust is in a constant state of flux, with solid slabs diving hundreds of miles down into the mantle as hot liquid magma rises up to fill the gaps. According to study author“¯Falko Langenhorst from the Friedrich Schiller University Jena, these forces...

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...
