Primary succession on the slopes University of Guam ecologist Thomas Marler recently mobilized efforts to characterize the vegetation that has recovered following the eruption of Mount Pinatubo, Philippines. "My interest was sparked by the paradox that this volcano's cataclysmic 1991 eruption was so powerful it changed global climate, yet after a full 15 years the biology of the recovering ecosystem had not been studied," said Marler. The void of research motivated the Guam ecologist to spend...

Lee Rannals for RedOrbit.com From just the first chapter, the genius of Clive Oppenheimer in the world of volcanology shines in his book "Eruptions That Shook The World."  This book is not for the faint at heart when it comes to literature, but obviously a book for one who is ambitious about learning. "In a way, what I wanted to do with the book was to imagine what the world would be like today if all the volcanoes had been switched off a few million years ago - how different would...

Mount Etna volcano on the island of Sicily erupted during the weekend, shooting flames 820-feet in the air and spewing lava down its slopes. Some are concerned about the effects the eruption will have on air travel, but the winds were blowing the ash away from the airport and no flights had been cancelled. According to the Italian Institute of Volcanology, the volcanic activity started on Saturday morning and continued through the day and overnight into Sunday. This is the fourth and the...

Geological history has periodically featured giant lava eruptions that coat large swaths of land or ocean floor with basaltic lava, which hardens into rock formations called flood basalt. New research from Matthew Jackson and Richard Carlson proposes that the remnants of six of the largest volcanic events of the past 250 million years contain traces of the ancient Earth's primitive mantle"”which existed before the largely differentiated mantle of today"”offering clues to the...

Nature of mysterious hot spot revealed by "photogeology" By Diana Lutz, Washington University in St. Louis Analysis of new images of a curious "hot spot" on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma. The unusual location of the province and the surprising composition of the lava that formed it offer tantalizing clues to the Moon's thermal history. The hot spot is a concentration of a radioactive element thorium sitting between...

A central Indonesian volcano that first started erupting last Thursday shot hot ash and smoke into their air again on Sunday in what the Telegraph considers "it's most powerful eruption yet." Mount Lokon, which is located on northern Sulawesi island, is a 5,184 foot volcano that until this past week had not erupted since 1991. Thousands of people were forced to evacuate from a two-mile zone surrounding the volcano, which according to BBC News shot ash, sand, and rocks some 4,800 feet into the...

Lava on the Caribbean island of Hispaniola indicates deep rock is 1 billion years older than previously thought Earthquakes and volcanoes are known for their ability to transform Earth's surface, but new research in the Caribbean has found they can also move ancient Earth rock foundations more than 1,000 miles. Two University of Florida geologists are part of a team that found lavas on the Caribbean island of Hispaniola "“ home to Haiti and the Dominican Republic "” that suggest...

One of Iceland's most active and most feared volcanoes looks like is getting ready to erupt, with measurements indicating magma movement, according to Icelandic experts on Wednesday, raising fears of a new ash cloud disrupting air traffic in Europe and abroad. The Hekla volcano, dubbed by Icelanders in the Middle Ages as the "Gateway to Hell," has erupted some 20 times over the past 1000 years, with the most recent eruption occurring on February 26, 2000. Hekla is close to the ash-spewing...

Latest research into the age of volcanos in Western Victoria and South Australia has confirmed that the regions are overdue for an eruption, potentially affecting thousands of local residents. Using the latest dating techniques, scientists from the University of Melbourne's School of Earth Sciences and the Melbourne School of Engineering have calculated the ages of the small volcanoes in the regions and established the recurrence rate for eruptions as 2,000 years. With the last volcano...

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

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...
