Earth’s Largest Extinction Event - Was It Caused By Siberian Volcanism?
2012-01-10 05:57:28

Around 250 million years ago, at the end of the Permian geologic period, there was a mass extinction so severe that it remains the most traumatic known species die-off in Earth´s history. Although the cause of this event is a mystery, it has been speculated that the eruption of a large swath of volcanic rock in Russia called the Siberian Traps was a trigger for the extinction. New research from Carnegie´s Linda Elkins-Tanton and her co-authors offers insight into how this volcanism...

Satellite imagery is showing Alaska´s Cleveland Volcano spewing ash 15,000 feet into the air from uninhabited Chuginadak Island about 940 miles southwest of Anchorage, USA Today is reporting. “It´s not expected to cause a disruption to big international air carriers,” U.S. Geological Survey (USGS) scientist-in-charge John Power said, who went on to call the event a “small explosion”. Air carriers in the region are showing a bit more concern, “any...

An undersea volcanic eruption that has been ongoing in the Atlantic Ocean south of the Canaries for more than a month now could be creating either a new island or an additional territory to the southern coast of El Hierro, said scientists studying the eruptions. For more than a month, burning lava and gases have been spewing up from the sea floor three miles south of El Hierro, the smallest of the seven Canary Islands. And on Tenerife, the most populous of the group of islands, 60 miles...

Image 1 - Researchers Fingerprint Hawaiian Lava

Lava fingerprinting reveals differences between Hawaii's twin volcanoes Hawaii's main volcano chains--the Loa and Kea trends--have distinct sources of magma and unique plumbing systems connecting them to the Earth´s deep mantle, according to UBC research published this week in Nature Geoscience, in conjunction with researchers at the universities of Hawaii and Massachusetts. This study is the first to conclusively relate geochemical differences in surface lava rocks from both...

Image 1 - NASA: No Evidence Of 2012 Supervolcano
2011-11-15 11:46:51

NASA said on Tuesday that there is no evidence of a massive supervolcano erupting in 2012, despite what some may believe. A supervolcano refers to an explosive volcanic eruption that eject about ten thousand times the quantity of magma and ash that Mount St. Helens expelled in 1980. NASA said Earth's surface has preserved clues of many massive supervolcanoes through hollowed-out calderas-craters that can be as big as 60 miles across after a volcano collapses from emptying out its entire...

Undersea Volcano Forming New Canary Island
2011-11-12 06:25:39

A new Canary Island is rising to the surface before our very eyes, and the first images of the infant volcano that is slowly coming up to the surface in the Spanish archipelago emerged on Friday. According to the Daily Mail, "Magma off the Canary Island of El Hierro has been spewing 20 meters high as the sea boils with a smell of sulfur“¦ As it grows and gets closer to the surface, more and more debris such as stones start to shoot out of the volcano which, until now, has only...

African Volcano Erupts With Impressive Show

Africa´s most active volcano Nyamuragira, located in the Democratic Republic of Congo, erupted last weekend throwing off clouds of ash and orange smoke, AFP reports. Located in the eastern areas of Virunga National Park, the volcano continues to erupt but was not considered a threat to locals or to the mountain gorillas living in the park, said Congo´s Center for Research and Natural Sciences. “A fountain of lava, smoke and ash came out of a fissure on the side” of...

On Oct. 9 an underwater volcano started to emerge in waters off El Hierro Island in the Canaries, Spain. Researchers of the Spanish Institute of Oceanography (IEO, Ministry of Science and Innovation) only needed 15 days to map its formation in high resolution. The volcanic cone has reached a height of 100 m and the lava tongue flows down its side, even though its activity has slowed down in the past few days. "This is probably the first time that such a young underwater volcano has been...

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...

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

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...

Eldfell

Eldfell is an active stratovolcano that is located in Iceland on the island of Heimaey, in the Vestmannaeyjar archipelago. It reaches an elevation of 656 feet and was created during a volcanic eruption on the east side of the island in 1973. Its name means Mountain of Fire in the Icelandic language. Iceland is an area with a high frequency of volcanic activity because it is located on top of the Iceland hotspot and beside the Mid-Atlantic Ridge. So many eruptions occur here that it is thought...

Kīlauea
2014-04-08 12:33:13

Kīlauea is an active shield volcano that is located on the island of Hawaii and is located within Hawaii Volcanoes National Park. This volcano, which reaches an elevation of 4,091 feet, is one of five volcanoes that form the island and it is the most active. It is thought to be between 300,000 and 600,000 years old and is the second youngest of all the Hawaii volcanoes. It was formed when the Pacific tectonic plate moved over the Hawaiian hotspot and like other Hawaiian volcanoes, it began...
