Study Shows Extrusive Volcanism Formed Hawaiian Islands
2013-10-07 09:17:25

A recent study changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought.

Eruptions Not Always Imminent From Slow Magma
2013-08-20 04:41:19

A new modeling study from the University of Washington reveals reservoirs of silica-rich magma of the sort that causes the most explosive volcanic eruptions can persist for hundreds of thousands of years in the Earth’s upper crust without triggering an eruption.

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.

Mercury May Have Hosted A Magma Ocean In Its Past
2013-02-21 13:29:25

Scientists analyzing data from NASA's MESSENGER spacecraft say that Mercury once harbored an ancient magma ocean.

Traces Of Water Found In Apollo 15 Lunar Sample

University of Michigan scientists have found traces of water from a lunar sample brought back during the Apollo 15 mission.

New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Neither explosive nor effusive—there’s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience.

Breaking Through The Crust: Unraveling The Magma Mystery
2012-11-30 13:54:20

Even though two-thirds of the Earth's solid surface is covered with oceanic crust, scientists still don't entirely understand the process by which it is made.

Trigger For Explosive Volcanic Eruptions Identified

Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports.

Greek Island Volcano Ballooning With Magma, Eruptions Not Imminent Researchers Say
2012-09-10 11:42:44

New scientific data from the Greek isle of Santorini shows signs of unrest for the first time in more than 50 years, and could be evidence of an impending eruption similar to the one that last struck in 1950

Parking Lot Lava Flows

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...

Chaitén
2014-08-28 10:38:21

Chaitén is a volcanic caldera that is located in southern Chile that reaches an elevation of 3,681 feet. It is thought that this volcano once held a rhyolite obsidian lava dome that reached 3,156 in height, but this was destroyed after its most recent eruption in 2008. In the past, this volcano has released grey obsidian, which was used by pre-Columbian cultures to make many objects, some of which have been found 250 miles away from the volcano. Chaitén experienced the beginning of a new...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....

Askja
2014-04-09 16:13:20

Askja is an active stratovolcano that is located in the isolated central highlands in Iceland. It reaches an elevation of 4,974 feet and its name literally means caldera, or box, in the Icelandic language. The area can only be reached during a period of a few months and because it located in the rain shadow of the Vatnajökull glacier to the northeast, it only receives 17.7 inches of rain per year. One of Askja’s smaller craters holds a lake known as Öskjuvatn, which is often frozen over...
