Latest Plate tectonics Stories
From the highest peak in the continental United States, Mt. Whitney at 14,000 feet in elevation, to the 10,000-foot-peaks near Lake Tahoe, scientific evidence from the University of Nevada, Reno shows the entire Sierra Nevada mountain range is rising at the relatively fast rate of 1 to 2 millimeters every year.
New research is casting doubts on the frequency or even the possibility of a ‘super-eruption’ that could blot out the sun from the Earth with a thick veil of volcanic ash.
Mexico's Popocatepetl Volcano has re-awakened and has been emitting gas and ash. NOAA's GOES-13 satellite has been viewing the ash cloud, and it was documented in a short new video released by NASA's GOES Project on Friday.
The Popocatepetl volcano located outside of Mexico City has started spewing ash and fragments of glowing, molten rock thousands of feet down its slopes, forcing officials at one of the world's largest cities to increase the volcano's alert level.
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to understanding plate ruptures and predicting eruptions—both of which are important steps for protecting the public from earthquake and volcanic hazards.
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions.
The April/May GSA Today science article is now online at www.geosociety.org/gsatoday/.
A new study published in the journal Nature Geoscience is suggesting that the human species may have taken much longer to evolve thanks to plate tectonics that changed Africa’s landscape millions of years before experts previously believed.
Topics in the 26 March posting of GEOLOGY include anthropogenic impacts on the Indus River into the Arabian Sea; possible electrical conductivity beneath the Yellowstone hotspot track; mountain-forming volcanoes and deadly debris flows; melting beneath the Colorado Plateau; widespread weathered glass on Mars; and a new view into Mars' global aqueous history.
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...
