Yellowstone: New Picture Emerges Of A More Active, Less 'Super' Volcano
2012-04-30 08:36:47

Brett Smith for Redorbit.com New research is casting doubts on the frequency or even the possibility of a ℠super-eruption´ that could blot out the sun from the Earth with a thick veil of volcanic ash. A joint research team from Washington State University and the Scottish Universities Environmental Research Centre said the biggest Yellowstone eruption on record was actually two different eruptions at least 6,000 years apart. According to the study published in the June...

Image 1 - Mars Express Helps Map History Of Martian Volcanic History
2012-04-27 04:03:23

Lee Rannals for RedOrbit.com Mars Express has helped to unveil volcanic history of the Red Planet, providing more insight as to what lies underneath our celestial neighbor. The spacecraft has been floating above Mars, mapping out the planet, for five years, during which it has helped researchers find that lava grew denser over time, and that the thickness of the planet's rigid outer layers varies across the Tharsis region. The measurements were taken while Mars Express was orbiting...

Image 1 - Lava Flows On Mars Resembles Patterns On Earth
2012-04-27 03:52:42

Lee Rannals for RedOrbit.com New photos taken by the High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter show unique lava flows on Mars that resemble patterns seen on Earth. The lava flows reveal coiling spiral patterns that resemble snail or nautilus shells, according to research published in the scientific journal Science on Friday. On Earth, lava coils can be found on the Big Island of Hawaii, mainly on the surface of ropey pahoehoe lava...

Satellite Provides Glimpse of One Week's Ash Activity From Mexico's Popocatepetl Volcano
2012-04-25 01:03:01

[ Watch the Video ] Satellites continue to provide a look at the ash and gas clouds being emitted from Mexico's Popocatepetl Volcano. NASA has animated imagery from NOAA's GOES-13 satellite to provide a week long look at the volcano's activity. "Most of the time, the prevailing westerly winds carry the debris (ash and smoke) far to the east in the mornings, while the daily rains bring down the ash before it can go far in the afternoon," said Dennis Chesters, of the NASA GOES Project at...

NASA Satellite Captures Video Of Mexico's Popocatepetl Volcanic Ash Cloud
2012-04-23 09:20:33

[ Watch the Video ] Mexico's Popocatepetl Volcano has re-awakened and has been emitting gas and ash. NOAA's GOES-13 satellite has been viewing the ash cloud, and it was documented in a short new video released by NASA's GOES Project on Friday. NOAA's Geostationary Operational Environmental Satellite, GOES-13, captures visible and infrared images of weather over the eastern U.S. every 15 minutes, and spotted an ash and gas cloud streaming from Mexico's Popocatepetl Volcano over several...

Eruption Threat Level Increased At Volcano Near Mexican Capital
2012-04-21 05:40:16

The Popocatepetl volcano located outside of Mexico City has started spewing ash and fragments of glowing, molten rock thousands of feet down its slopes, forcing officials at one of the world's largest cities to increase the volcano's alert level, BBC News and the Associated Press (AP) are reporting. The volcano, which is also commonly referred to as 'Popo,' has been expelling small amounts of ash on an almost daily basis since entering a round of eruptive activity back in 1994, the AP...

Volcanic Plumbing Provides Clues on Eruptions and Earthquakes
2012-04-13 03:49:08

Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to understanding plate ruptures and predicting eruptions–both of which are important steps for protecting the public from earthquake and volcanic hazards. International teams of researchers, including two scientists from the University of Rochester, have been studying the location and behavior of magma chambers on the Earth's mid-ocean ridge system–a vast chain of volcanoes along...

Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions. International teams of researchers, led by the University of Leeds, studied the location and behavior of magma chambers on the Earth's mid-ocean ridge system - a vast chain of volcanoes along which the Earth forms new crust. They worked in Afar (Ethiopia) and Iceland - the only places where mid-ocean ridges appear above sea level. Volcanic ridges (or...

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

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...
