Latest Plate tectonics Stories
In this three-part series, University of Alberta geophysicist Martyn Unsworth records his expedition to Antarctica's volcanic Mount Erebus, and how it's rifting apart the continent.
Sudden tectonic plate movements have puzzled scientists for decades, but now they believe they have the answer. And like fried chicken, it's all in the crust.
Tonga, an island 1,243 miles northeast of New Zealand, has sparked the world’s attention through the Tongan volcano eruption, resulting in the creation of a new physical island.
Best known for building complex machines to explore the far reaches of space, NASA’s Jet Propulsion Laboratory (JPL) is developing robots designed to explore something a little closer to home: the insides of a volcano.
Small volcanic eruptions could have played a role in the so-called “warming hiatus” that has taken place over the past 15 years, Lawrence Livermore National Laboratory researchers report in a recent edition of the journal Geophysical Research Letters.
Covered mostly by a massive ice sheet, Greenland is known for not being very green. But new research suggests otherwise.
Volcanic eruptions in Iceland are pretty commonplace. Forming new layers of the Earth's crust during an eruption? That's new (at least to us).
Radar images from the Sentinel-1A satellite are helping to monitor ground movements of the recently erupted Fogo volcano.
If Brad Singer knew for sure what was happening three miles under an odd-shaped lake in the Andes, he might be less eager to spend a good part of his career investigating a volcanic field that has erupted 36 times during the last 25,000 years.
A homeowner’s policy will cover fire damage from a volcanic eruption, the policy may not cover water, ash, or earthquake damage, says Darras. Ontario, CA (PRWEB)
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 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 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 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...
