Friday saw another round of volcanic explosions at Alaska's Mount Redoubt, shooting ash clouds as high as 50,000 feet above sea level and sending drivers on a run to the auto parts store for replacement air filters, the Associated Press reported. The majority of the ash was anticipated to fall to the north, the National Weather Service proposed, however slight amounts of ash from two Friday eruptions, as well as smaller overnight eruptions, could send ash falling on Anchorage itself. ...

Using radar images acquired by ESA satellites from 1992 to 2006, scientists have for the first time been able to monitor the long-term behavior of Mt. Etna, Europe's highest and most active volcano. This unprecedented time series of Synthetic Aperture Radar (SAR) observations from ESA's ERS-1, ERS-2 and Envisat satellites provided crucial information for understanding how the volcano's surface deformed during the rise, storage and eruption of magma. Changes in surface deformation, such as...

For the first time in nearly 20 years, the 10,200-foot Mount Redoubt in Alaska erupted five times overnight Sunday, propelling a 9 mile cloud of ash into the air, the Associated Press reported.  Although residents of the state's most populated city did not witness any falling ash, small communities just north of Anchorage observed bits of falling, fine gray dust on Monday. In a small 24-hour grocery store located in Willow, a small town just 50 miles north of Anchorage, 56-year old,...

Scientists at volcano monitoring stations in Alaska say they are confident in their abilities to track volcanic activity at the active Redoubt Volcano. The scientists stationed at the Alaska Volcano Observatory in Anchorage and the city of Fairbanks, said the monitoring stations have made significant advancement since the volcano's 1989 eruption, the Anchorage Daily News said Sunday. The Redoubt Volcano has been the source of recent volcanic activity, leading to concerns it may soon erupt....

Japan's Mount Asama volcano erupted early Monday sending plumes of smoke more than one mile into the air and spreading ash over parts of Tokyo. So far, officials have reported no injuries related to the eruption that occurred just 90 miles northwest of the capital city. Ash was detected over a wide area, including central Tokyo and as far as eastern Chiba.The volcano previously erupted in August 2008. No major damage was reported during that blast either. Many residents were puzzled about the...

In the latest sign that an eruption could be imminent, further seismic activity has been detected at Alaska's Mount Redoubt, scientists reported Saturday.  "Since late Friday afternoon, seismic activity has been relatively low at Redoubt; however, it is still above normal background levels," the Alaska Volcano Observatory said early Saturday. "The volcano is in a state of unrest," it said. Geologists monitoring the volcano for indications of a possible eruption noticed that a hole in...

Alaska's Mount Redoubt volcano is expected to erupt at any time now and scientists are keeping a watchful eye on the volcano's hour-to-hour activity. The Alaska Volcano Observatory told CNN news that Redoubt's seismic activity level of has increased markedly in recent days at the 10,197-foot peak located about 100 miles southwest of Anchorage, the state's most populous city. Peter Cervelli, a research geophysicist with the observatory, is keeping a watchful eye on the volcano. "We don't have...

When volcanoes erupt, pinpointing the regions at high risk for lethal hazards and deciding whether or not to evacuate a resistant population comprise the most difficult problems faced by hazards managers. Now a team of volcanologists has a program that maps potential problem areas quickly, taking much of the guesswork out of decision making and evacuations. "We wanted to be able to predict the areas affected by pyroclastic flows from volcanoes," said Christina Widiwijayanti, post-doctoral...

But global warming may have helped override some recent eruptions Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics "” but suggest that such effects may have been masked in the 20th century by rising global temperatures. Their paper, which shows that higher latitudes can be even more sensitive to volcanism, appears in the current issue of Nature Geoscience. Scientists already agree that large eruptions have...

The Chaiten Volcano, which erupted in May for the first time in thousands of years, was said by Chile's government on Friday to still not be safe and that a decision regarding the future of the town of Chaiten would be made in the coming days, The volcano is forcing 7,000 residents to evacuate.  It is located only six miles from the town and started to spew ash, gas and molten rock on May 2. For weeks, constant eruptions were forcing a cloud of debris to keep aloft which soared as high...

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...

Zubair Group

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

Kohala

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

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...

Santa María Volcano

Santa María Volcano is an active stratovolcano that is located in Guatemala and is part of the Sierra Madre, a string of volcanoes that stretches across the western side of Guatemala. The volcanoes in this string were formed by subduction activity, when the Cocos Plate moved under the Caribbean Plate. An eruption in 1902 produced a crater that now holds a lava dome known as Santiaguito, which was created during another eruption in 1922. These domes hold active vents and in 1929, part of the...
