NEW YORK, Nov. 1, 2010 /PRNewswire/ -- The project known as The World Park, an event and campaign created for New York's Parks and Recreation group, launched in Central Park on Arbor Day weekend 2010.
Mount Merapi launched lava and hot ash into the skies for the fourth time in eight days Wednesday morning, sending villagers and refugees scurrying to move further away from the Indonesian volcano following its most intense eruptions yet.
Nevada and Hawaii researchers complete study of Kilauea health clinic records.
Scientists are crediting satellite imagery with helping to predict where volcanic eruptions could strike. It is well known that earthquakes can stress Earthâ€™s crust and trigger subsequent quakes, but there has been no proof of this for volcanoes until now.
New research suggests that climate change following massive volcanic eruptions drove Neanderthals to extinction and cleared the way for modern humans to thrive in Europe and Asia.
Researchers working with the British Geological Survey (BGS) are studying ash samples collected from the EyjafjallajÃ¶kul volcano that could shed new light on the dispersion of volcanic ash following an eruption.
A better way to pinpoint where volcanic eruptions are likely to occur has been produced by an international team of geophysicists.
Geologists reported on Sunday that a swarm of small earthquakes that struck western Saudi Arabia last year was actually the rumbling of a volcano.
The heat in the atmosphere of Venus, induced from a strong greenhouse warming, might actually have a cooling effect on the planet's interior.
Experts say that another volcanic eruption on Iceland could happen again soon, but will likely cause much less chaos than the one that caused air traffic to shutdown earlier this year.
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 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 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 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 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...
