2014-05-03 05:03:06

While magma levels are rising at Mount St. Helens in Washington, there is now evidence that the active stratovolcano will not be erupting any time soon.

Origins On The Behavior Of Hawaiian Volcanoes
2014-05-01 03:05:10

Kīlauea volcano, on the Big Island of Hawai'i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island.

Mount Hood Study Suggests Dormant Volcanoes Quickly Become Active
2014-02-17 07:22:37

New research by UC Davis and Oregon State University may soon lead to new forecasts into how soon volcanoes are ready to erupt. The team found that in order for an eruption to occur, molten rock under the volcano must be sufficiently mobile.

Iceland's Basalt Pillars Not From Warring Trolls, As Folk Legend Has It
2014-02-04 13:18:11

Folklore says that mysterious basalt pillars found in Iceland were created by a pair of angry trolls who hurled rocks at one another. However, a new study says that these pillars actually formed around vertical columns of steam and hot water venting through lava.

Large Magma Chamber Sits Below World’s Most Active Volcano
2014-01-29 13:29:50

A team of researchers have discovered a large magma chamber deep under the most active volcano in the world. It is the first time research has been able to confirm such a discovery in Kilauea's depths.

A University of Houston (UH) geoscientist and his colleagues are revealing new discoveries about the Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean.

Volcanic Rock Research Sheds New Light On Earth’s Formation
2013-11-08 12:29:31

By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated.

Scientists Look At Supervolcano Life Cycle In Whole New Way
2013-10-11 14:49:13

Studies of zircon in Yellowstone rocks are giving scientists a whole new look at the life cycle of supervolcanoes.

Iceland's Basalt Pillars Formed By Slow Lava And Water
2013-10-09 15:55:39

a new study indicated that bizarre pillars of basalt in Iceland's Skaelingar valley were formed by a very slow lava flow oozing from volcanoes and interacting with water.

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...
