Latest Plate tectonics Stories
Researchers on board the Integrated Ocean Drilling Program's research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. Scientists studying these returned samples have found the first direct evidence of life deep within these samples.
While we never managed to find the lost city of Atlantis, an international group of scientists has found evidence of an ancient lost micro-continent resting beneath two islands in the Indian Ocean.
A team of atmosphere chemists has devised a chemical trick for determining which historical cooling periods are the results of volcanic eruptions.
As we are quickly approaching the two-year anniversary of the Tohoku-Oki earthquake that prompted the devastating Honshu tsunami, we learned this week about a rapid-response drilling operation at the site of the earthquake.
A University of Utah seismologist analyzed seismic waves that bombarded Earth's core, and believes he got a look at the earliest roots of Earth's most cataclysmic kind of volcanic eruption. But don't worry. He says it won't happen for perhaps 200 million years.
India collided with Asia, creating the Himalayas, 10 million years later than previously thought, according to new research published in Earth and Planetary Science Letters.
Despite the absence of any recent tectonic activity in the area, one region of the Appalachian Mountains looks vastly different from its surroundings, leading a team of US researchers to conclude that the location had undergone a transformation they refer to as a “geological facelift.”
Neither explosive nor effusive—there’s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience.
Researchers for the first time have discovered evidence supporting the theory that the processes that act as catalysts for volcanic activity today are similar to those that occurred nearly four billion years ago.
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...
