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

Volcanism in the Yellowstone region was caused by the defunct pieces of a former mantle plume that were severely deformed. Circulation currents, driven by the movement of tectonic plates at the Cascades subduction zone, also affected the plume.

Unmanned Aircraft Used To Help Study Volcanic Plumes
2013-04-02 05:11:35

Last month, Earth science researchers from NASA traveled to Turrialba Volcano near San Jose, Costa Rica. The research team was there to study the chemical environment of the volcano by flying a Dragon Eye unmanned aerial vehicle into the sulfur dioxide plume and over its summit crater.

Geologists Say Earth Is Congested

According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions.

Deep Magma Imaged Beneath Pacific Seafloor Volcano
2013-03-28 04:51:18

By using electromagnetic technology to map a large area of seafloor near Central America and the northern East Pacific Rise, researchers from the Scripps Institution of Oceanography report that they have a better idea of the origin of the erupted magma that eventually becomes new seafloor.

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

One of Iceland’s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak.

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. But scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event.

Magma May Be Natural Lubricant For Moving Tectonic Plates
2013-03-21 11:09:11

Scientists from the University of California, San Diego’s Scripps Institution of Oceanography (SIO) have discovered a liquefied layer of molten rock in the planet’s mantle – a substance which could be acting as a lubricant of the sliding motions of the Earth’s tectonic plates.

Scientists Solve Mystery Of California Tectonics
2013-03-19 12:50:14

A team of American scientists believe they have solved a geological mystery buried about 100 miles below California.

Model Shows How Carbon Escapes From Deep Earth To Surface
2013-03-19 11:46:54

Computer simulations of water under extreme pressure reveals how carbon might one day be recycled from hundreds of miles below the surface of the Earth, according to researchers at the University of California, Davis and Johns Hopkins University.

Nyamuragira
2014-10-04 17:56:14

Nyamuragira is an active shield volcano that is located in the Democratic Republic of the Congo. This volcano, which is part of the Virunga Mountains, reaches an elevation of 10,033 feet and is the most active volcano in Africa. This volcano is shorter than Nyiragongo, which it shares an area with, and has a low shield profile. It holds a large amount of sulfur dioxide and is blamed for much of the volcano related sulfur dioxide content in the atmosphere. Nyamuragira has erupted over forty...

Imbabura Volcano
2014-10-04 17:36:59

Imbabura Volcano is an inactive stratovolcano that is located in Ecuador and is part of the southern Ring of Fire and one of many volcanoes created along an arc by the subductions of the Coolyo Plate underneath the South American Plate. This volcano was shaped by strombolian eruptions, which are less violent than plinian eruptions and are characterized by the expulsion of lapilli, lava bombs, and cinders as well as the accumulation of tephra around the point of eruption like a vent....

Mount Nyiragongo
2014-08-28 11:22:30

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...
