A new study finds that the closing of some European airports last year during and after volcanic eruptions in Iceland was the proper thing to do, and may have saved lives. The eruption of ash from Eyjafjallajokull resulted in the largest closure of European airspace since World War II, with losses estimated at around $2 billion. Concerns about aircraft safety during the eruptions were well founded, as ash particles from the initial phase of the eruptions were particularly abrasive, posing a...

The composition of a vast plume of hot rock and briny fluid 200 miles beneath Yellowstone National Park's surface has been mapped, a soon-to-be published study says. Researchers are able to receive a clear picture of the type of material that activates Yellowstone's volcanic features through these "geoelectric" images of the plume, says study co-author Robert B. Smith, professor emeritus at the University of Utah and coordinating scientist of the Yellowstone Volcano Observatory. "This is the...

Conductivity image hints volcano plume is bigger than thought University of Utah geophysicists made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image suggests the plume is even bigger than it appears in earlier images made with earthquake waves. "It's like comparing ultrasound and MRI in the human body; they are different imaging technologies," says geophysics...

The Kilauea volcano that recently erupted on the Big Island of Hawaii will be the target for a NASA study to help scientists better understand processes occurring under Earth's surface. A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., departed on Sunday, April 3, from the Dryden Aircraft Operations Facility in Palmdale, Calif., to the Big Island for a nine-day mission. The Uninhabited Aerial Vehicle...

National Geographic writer Michael Finkel has written a special piece about a team of seismologists and their exploration of the Nyiragongo Volcano in the Democratic Republic of the Congo.  The setting of the report lies in its vivid painting of a team passionate about exploring this volcano, which threatens about a million people who live 12 miles south in the city of Goma. Finkel describes the efforts taken to gain a better understanding of Nyiragongo and its future impact on the...

A volcanologist said on Friday that Indonesia issued a red alert after Mount Karangetang on the island of Sulawesi erupted, sending lava and searing gas clouds down its slopes. "We raised the volcano's status to the highest red alert level today at 5:45 pm (1045GMT) and ordered an evacuation in three villages on the slopes," government volcanologist Surono told AFP. He said that the 5,850-foot mountain on the island off North Sulawesi oozed lava, heat clouds and debris reaching as far as...

A fissure on Kilauea Volcano on the Big Island of Hawaii sent lava spewing more than 60 feet into the air recently, and scientists continued to monitor the activity closely. Park rangers said that no homes were threatened in the latest blast and also cautioned campers and visitors to keep their distance while it continues to act up. Kilauea has been constantly erupting for the past 28 years. But according to geologist Janet Babb of the US Geological Survey (USGS), this weekend's activity...

Eruptions at a Hawaiian volcano have forced officials to close off part of a national park to visitors while geologists monitor eruptions and other seismic activity in the area. According to the Daily Mail, US Geological Survey (USGS) scientists working at the Hawaiian Volcano Observatory (HVO) have reported "a fountain of fire" at the Kilauea Volcano. The volcano in question is located near Napau Crater in Hawaii County, and began erupting Saturday afternoon. "That event was nearly...

No matter their size or shape, explosive volcanoes produce tremors at similar frequencies for minutes, days or weeks before they erupt. In the Feb. 24 issue of the journal Nature, researchers at Yale University and the University of British Columbia (UBC) describe a model that explains this strange phenomenon "“ and may help forecast deadly eruptions. When such volcanoes erupt they can shoot hot ash up to 40 kilometers into the atmosphere and cause devastating destruction when the ash...

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...
