For the first time, researchers have taken a detailed look at what lies beneath all of Iceland's volcanoes "“ and found a world far more complex than they ever imagined.  They mapped an elaborate maze of magma chambers - work that could one day help scientists better understand how earthquakes and volcanic eruptions occur in Iceland and elsewhere in the world. Knowing where magma chambers are located is a key first step to understanding the chemical composition of the molten rock...

Volcanoes are notoriously hard to study. All the action takes place deep inside, at enormous temperatures. So geophysicists make models, using what they know to develop theories about what they don't know. Research led by Gregory P. Waite, an assistant professor of geophysics at Michigan Technological University, has produced a new seismic model for figuring out what's going on inside Mount St. Helens, North America's most active volcano. Waite hopes his research into the causes of the...

Scientists using NASA satellite data have found strong evidence that a major earthquake can lead to a nearly immediate increase in regional volcanic activity. The intensity of two ongoing volcanic eruptions on Indonesia's Java Island increased sharply three days following a powerful, 6.4-magnitude earthquake on the island in May 2006. The increased volcanic activity persisted for about nine days. "During this period, we found clear evidence that the earthquake caused both volcanoes to...

TOKYO (Reuters) - Japanese vulcanologists have warned of more eruptions at a volcano on the southern island of Kyushu, as volcanic activity has been intensifying at one of its craters. The Meteorological Agency has issued a bulletin warning of a high possibility of eruptions at the Showa vent, one of the craters on Sakurajima on the southern tip of Japan's southern island of Kyushu, about 1,000 km (600 miles) southwest of Tokyo. The agency upgraded the 1,000 meter (3,200 foot) high...

ANCHORAGE, Alaska -- From his home in Nanwalek, Vince Evans can stare across the water at Augustine Volcano as it pumps out clouds of ash and steam, but like many residents in the isolated village, Evans prefers to check the Internet for the latest on the erupting island mount. The Alaska Volcano Observatory's popular Web site lets the public track Augustine's activity, from live earthquake data to hourly updates on the blasts of ash and rocky pyroclastic flows that have rumbled down the...

WASHINGTON (AP) -- While Mount St. Helens and Kilauea generate the most attention, many other volcanoes in the United States have little or no regular monitoring and need to be watched for potential eruptions, a new report warns. The U.S. Geological Survey said Friday that monitoring gaps exist for volcanoes in Alaska, California, Washington, Oregon, Hawaii, Wyoming and the Northern Mariana Islands that could pose a hazard both on the ground and to aviation. The report reviews the hazard of...

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....
