Latest Lava dome Stories
Ten years ago Wednesday, Mount St. Helens in Washington erupted after being quiet for nearly two decades, and now US Geological Survey (USGS) scientists are concerned that the volcano could mark the occasion by becoming active once again.
On the ground and in the water, an international team of researchers has been collecting imaging data on the Soufriere Hills Volcano in Montserrat to understand the internal structure of the volcano and how and when it erupts.
Until earlier this week, the most recent significant tremor at Mount St. Helens was in October of 2004. On Sunday January 13th, some steam was rising from a fracture in Mount St. Helensâ€™ crater.
Hot clouds from Indonesia's Mount Merapi dissipated on Thursday, a day after spreading far enough to blanket villages with ash and prompting authorities to put the volcano back on top alert again.
Mount Merapi's unstable lava dome has partially collapsed, easing pressure that threatened to make the Indonesian volcano erupt.
By Adi Kurniawan MOUNT MERAPI, Indonesia (Reuters) - Indonesia's Mount Merapi could be downgraded from its top alert status soon as the volcano has spewed less hot gas and molten lava in recent days, an expert said on Monday.
By Jalil Hamid YOGYAKARTA, Indonesia (Reuters) - Dozens of Indonesians prayed in the shadow of the rumbling Mount Merapi volcano on Friday as it spewed smoke, and a preacher urged people to remain calm.
Indonesia has evacuated about 2,000 people from areas at risk from a volcano spewing hot gas and lava, and expects to move thousands more amid signs of increased activity from Mount Merapi, officials said on Tuesday.
SEATTLE (Reuters) - A rock fall at Mount Saint Helens caused a large gray cloud of dust to appear above the volcano on Tuesday, but there was no sign of increased seismic activity.
In September 9 story headlined "Scientists find growing land bulge in Oregon," please read in first paragraph, "A large, slow-growing volcanic bulge in Western Oregon," instead of "A large, slow-growing volcanic bulge in Eastern Oregon." A corrected story follows: By Teresa Carson PORTLAND, Oregon (Reuters) - A large, slow-growing volcanic bulge in Western Oregon is attracting the attention of seismologists who say that the rising ground could be the beginnings of a volcano or simply...
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...
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...
