The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and 2005. Now a new study, funded by the National Science Foundation, shows that the residents of that region are at risk from yet another potentially deadly natural phenomenon — major volcanic eruptions. Researchers from Oregon State University working with colleagues in Indonesia have documented six major...

Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions. International teams of researchers, led by the University of Leeds, studied the location and behavior of magma chambers on the Earth's mid-ocean ridge system - a vast chain of volcanoes along which the Earth forms new crust. They worked in Afar (Ethiopia) and Iceland - the only places where mid-ocean ridges appear above sea level. Volcanic ridges (or...

  In his new book, ℠Deep-Sky Companions: The Secret Deep,´ Stephen James O'Meara presents 109 new objects for stargazers to observe. The Secret Deep contains many exceptional objects, including a planetary nebula whose last thermal pulse produced a circumstellar shell similar to the one expected in the final days of our Sun's life; a piece of the only supernova remnant known visible to the unaided eye; the flattest galaxy known; the largest edge-on galaxy in the heavens;...

Mount Etna Begins 12th Eruption Of Year

  Italy´s famed volcano Mt. Etna has erupted for the twelfth time this year, spewing lava and ash into the upper atmosphere, according to an Associated Press report. Italy´s Civil Protection Agency says the nation´s geophysics and volcanology institute on Monday registered increased explosive activity by Etna, eight days after the latest eruption began, spewing out a significant amount of ash in a southeast direction early in the day but that the eruption tapered off...

The Soufriere Hills Volcano on Montserrat erupted in 1995, and an international team of researchers has studied this volcano from land and sea since then to understand the workings of andesite volcanos more completely. "To the extent that the Soufriere Hills Volcano is typical of andesitic dome building volcanoes, results from this research can be expected to apply more generally," said Barry Voight, professor emeritus of geosciences, Penn State. Voight and R. S. J. Sparks, the Channing Wills...

Alaska's Mount Redoubt has gradually slowed down in activity since the last eruption three months ago. The Alaska Volcano Observatory said on Tuesday that seismic activity has calmed down and the eruptions may have stopped. The observatory has dropped the alert levels for the areas around the mountain. Several eruptions starting in March interrupted air traffic and covered Anchorage, the Kenai Peninsula and Wasilla with ash. Due to prior events, geologists felt that the eruptions would be...

The U.S. government will spend $15.2 million to modernize equipment for monitoring U.S. volcanoes and improving warning systems, according to Interior Secretary Ken Salazar. Salazar said the United States and its territories have 169 active volcanoes, and 54 of them need improved monitoring so scientists can warn the public about explosive disruptions, alert aircraft to ash clouds and inform communities of falling ash, lava and mud flows. One example Salazar cited was the recent activity of...

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....

A controversial new study based on findings from an analysis of records in southern Chile suggests that very large earthquakes can trigger an increase in activity in nearby volcanoes. The researchers noticed that up to four times as many volcanic eruptions occurred during the year following very large earthquakes than did so in other years. They say volcanoes around 300 miles away from an earthquake's epicenter were affected. In the past, scientists had identified only a few cases where...

Scientists have exploited crystals from lavas to unravel the records of volcanic eruptions. The team, from Durham University and the University of Leeds, studied crystal formation from a volcano, in Santorini, in Greece, to calculate the timescale between the trigger of volcanic activity and the volcano's eruption. They say the technique can be applied to other volcanoes "“ such as Vesuvius, near Naples, in Italy "“ and will help inform the decisions of civil defense agencies....

Volcanology
2014-01-12 00:00:00

Volcanology is the study of volcanoes, magma, lava, and related geological, geochemical, and geophysical phenomena. The term volcanology comes from the Latin word Vulcan. Vulcan is the ancient Roman god of fire. A volcanologist is a person who studies the creation of volcanoes, and their current and historic eruptions. Volcanologists frequently visit volcanoes, particularly active ones, to observe volcanic eruptions, collect eruptive products including samples of tephra, lava, and rock....
