April Flowers for redOrbit.com - Your Universe Online According to an international team of scientists, led by the University of Durham, UK, the recent storms that have battered the east coast of America may have been much more frequent in the region 450 million years ago. The findings of their study, published in the journal Geology, pinpoint the positions of the Equator and the landmasses of the USA, Canada and Greenland, during the Ordovician Period 450 million years ago,...

Volcanic Eruptions Predicted With Satellite Imagery
2012-11-05 14:28:53

Brett Smith for redOrbit.com - Your Universe Online In a new report published in the journal Geophysical Research Letters, two scientists showed they may now be able to detect signs of an impending volcanic eruption by analyzing satellite imagery. Using Interferometric Synthetic Aperture Radar (InSAR) over the active volcanoes in Indonesia's west Sunda arc, the vulcanologists from University of Miami uncovered evidence that showed the ℠inflation´ of several volcanoes prior to...

Hawaiian Volcanoes Compete For The Same Magma Supply
2012-10-24 06:12:27

April Flowers for redOrbit.com - Your Universe Online About 50 miles underground, there is a deep connection between two of Earth's most notable volcanoes, Hawaii's Mauna Loa and Kilauea, that could explain some of their enigmatic behavior. A new study, led by Rice University, is the first to model paired volcano interactions. It explains how a link in Earth's upper mantle could account for the competition between Kiluea and Mauna Loa for the same deep magma supply. The results of this...

Trigger For Explosive Volcanic Eruptions Identified
2012-10-13 09:27:11

Lee Rannals for redOrbit.com — Your Universe Online Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports. University of Southampton researchers investigated crystal cumulate nodules and their trapped magma to see what caused eruptions at the Las Cañadas volcanic caldera on Tenerife, in the Canary Islands. This volcano has generated at least eight major...

Indonesia Volcano Lets Out Roar Over Weekend
2012-10-08 14:49:15

Lee Rannals for redOrbit.com — Your Universe Online An active Indonesian volcano erupted once again, spewing out clouds of ash and alarming residents as far as three miles away. Mount Lokon, a 5,214-feet volcano on northeast Sulawesi island, has been very active recently, and on Sunday it added another eruption to its track record. Since its biggest eruption in July 2011, when over 5,200 people were evacuated, Mount Lokon has erupted and spewed clouds of ash about 600 times....

Super-Earths May Not Be As Earth-Like As Name Suggests
2012-09-26 14:10:34

Lee Rannals for redOrbit.com — Your Universe Online A new study presented at the European Planetary Science Congress on Wednesday shows just how rare our Earth really is. Super-Earths are out there, and exoplanet hunters estimate there could be billions of the planets. However, the new research suggests that just because they are Super-Earths, doesn't mean they are capable of hosting life. "We are discovering planets orbiting distant stars that are similar to Earth in...

Greek Island Volcano Ballooning With Magma, Eruptions Not Imminent Researchers Say
2012-09-10 11:42:44

Lawrence LeBlond for redOrbit.com - Your Universe Online New scientific data from the Greek isle of Santorini has shown signs of unrest for the first time in more than 50 years, and could be evidence of an impending eruption similar to the one that last struck in 1950, but far less catastrophic than the one that wiped out Minoan settlements on the island of Crete some 3,600 years ago. The Santorini volcanic eruption circa-1650 BC formed a large crater, or caldera, which is now flooded...

Dinosaur Extinction Event Wasn't The First
2012-09-06 07:58:40

April Flowers for redOrbit.com - Your Universe Online Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet. A new study from the University of Washington, published in Palaeogeography, Palaeoclimatology, Palaeoecology, indicates that a separate extinction came shortly before that, triggered by volcanic eruptions that warmed the planet and killed life on the ocean floor. A six-mile wide asteroid slamming...

Indonesia Volcano Unleashes Cloud Of Ash, Warnings Issued
2012-09-05 15:02:13

Brett Smith for redOrbit.com - Your Universe Online Clouds of volcanic ash from Anak Krakatau, or child of Krakatau, have become so prominent in recent days that Indonesian authorities have issued a warning for local residents and tourists. "The ash was carried by wind from the southeast to the south, reaching Bandarlampung," Nurhuda, head of the observation and information section of the Meteorology, Climatology and Geophysics Agency (BMKG) in Lampung province told state news agency...

Exposure to volcanic ash can increase respiratory symptoms such as an extreme cough, or phlegm, according to a new study. The research, which will be presented today (4 September 2012) at the European Respiratory Society's Annual Congress in Vienna, investigated the effects of living close to the Icelandic Volcano, Eyjafjallajökull. Eyjafjallajökull erupted in April 2010 and created a huge ash cloud which spread across Europe, causing widespread disruption to...

Mount Nyiragongo is an active stratovolcano that is located in the Democratic Republic of the Congo. This volcano is part of the Virunga Mountains and is located in Virunga National Park. It reaches an elevation of 11,385 feet and has a crater that reaches 1.2 miles in width. This crater typically holds a lava lake that has varied between 2,000 and 10,660 feet in depth. It is not known how long this volcano has been active, but at least 34 eruptions have been recorded since 1882. Mount...

Nevado del Ruiz, also known as La Mesa de Herveo, is an active stratovolcano that is located along the border of the Colombian territories, or departments, of Caldas and Tolima. It reaches an elevation of 17,457 and is shaped like a cone. This volcano is protected within Los Nevados National Natural Park, along with many other volcanoes, and it is a popular tourist destination. Winter activities like skiing are conducted here as well as hiking and fishing. Nevado del Ruiz is part of the...

Galeras
2014-08-28 10:56:28

Galeras is a stratovolcano that is located in Nariño, a Colombian controlled territory. This volcano, which reaches a height of 14,029 feet, is highly active and the most active volcano in Colombia. It primarily contains andesite and holds two calderas that were created by eruptions in the past 560,000 years. Although it is shaped like a horseshoe, eruptions have caused a cone shaped structure to build up in one of the calderas. It was labeled a Decade Volcano in 1991, despite its recent...

Villarrica

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...

Hoodoo Mountain
2014-08-19 10:23:50

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...
