Latest Plate tectonics Stories
Exposure to volcanic ash can increase respiratory symptoms such as an extreme cough, or phlegm.
Over the last 50 million years, the Caribbean islands have been pushed east, driven by the movement of the Earth's viscous mantel against the more rooted South American continent.
The growth of high topography on the Tibetan Plateau in Sichuan, China, began much earlier than previously thought, according to an international team of geologists who looked at mountain ranges along the eastern edge of the plateau.
For decades, scientists thought the only place in our solar system that consisted of plate tectonics was right here on Earth. However, according to new research, the Red Planet may also be undergoing the same tectonic plate movement.
A long-dormant New Zealand volcano erupted on Monday, spewing an ash cloud that disrupted flights and closed highways.
A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recurrence frequency.
On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle.
The most dangerous fault line on the island of New Zealand is the Alpine Fault.
In addition to being fairly unpredictable, volcanoes can eject a wide range of material, from mile-high plums of black ash to a deadly hail of fist-sized pumice.
Although volcanic scientists are able to approximate the age of lava flows, determining the exact timing of each of a volcano’s eruptions has proved difficult in the past.
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...
