Improved Eruption Forecasts May Come Via Costa Rican Volcano Study
2013-08-01 07:54:55

A new study, led by Columbia University's Lamont-Doherty Earth Observatory, suggests the 1960's eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought.

In 2006 the island of Java, Indonesia was struck by a devastating earthquake followed by the onset of a mud eruption to the east, flooding villages over several square kilometers and that continues to erupt today.

Earth's Origins May Be Explained Through Mantle's 'Hidden Flux'
2013-07-17 14:46:32

One of the more popular theories surrounding the formation of the planets involves the countless collisions of smaller objects in orbit around the sun 4.5 billion years ago. However, proponents of that theory are missing one thing: the Earth's chemical composition is distinctly different from the meteors that are currently striking the planet.

Corn Syrup Model Predicts Yellowstone Geophysical Behavior

Researchers from Australia and the United States have created a model explaining the geophysical processes occurring in the Pacific Northwest using corn syrup, fiberglass and a series of pistons.

Global Distribution Of Sulfur Particles Following Large Eruptions Modeled By GEOMAR Researchers

How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia?

Upwellings In Earth's Mantle Have Remained Stable Over Geologic Time
2013-06-27 08:33:06

A new study from the University of Hawaii - Manoa's School of Ocean and Earth Science and Technology (SOEST) reveals that the large-scale upwelling within Earth’s mantle mostly occur in only two locations: beneath Africa and the Central Pacific.

Two Alaskan Volcanoes Release More Energy, Stronger Eruptions Ongoing

Two of three active Alaskan volcanoes have shown a sizeable increase in activity since first erupting weeks ago, according to the Alaska Volcano Observatory (AVO).

Earthquake researchers have now identified a 30 kilometers long and ten kilometers deep area along the North Anatolian fault zone just south of Istanbul that could be the starting point for a strong earthquake.

Embryonic Subduction Zone Could One Day Unite Continents

The activation of a passive plate boundary in the Atlantic Ocean could ultimately result in continental Europe moving closer to the US, according to new research appearing in the journal Geology.

The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do. But now, geochemists from Brown University have found a mineral structure with which the nobles deign to fraternize. Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...

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...
