Beautiful views and exotic thrills draw millions of tourists to volcanic sites each year. Previously frequented by smaller numbers of experienced hikers and trained tour guides, today's volcanic sites are plagued by throngs of novice hikers, who are often ill-prepared and uneducated about the risks of volcano geotourism. These groups of vacation-goers often display a lackadaisical attitude about safety that can put their lives at risk. The most obvious hazard is exposure to lava, but other...

Mechanism of evolution of the primordial metabolism discovered Volcanic-hydrothermal flow channels offer a chemically unique environment, which at first glance appears hostile to life. It is defined by cracks in the crust of the earth, through which water flows, laden with volcanic gases are contacting a diversity of minerals. And yet — it is precisely this extreme environment, where the two mechanisms could have emerged, which are at the root of all life: The multiplication of...

By Steve Koppes, University of Chicago Geochemist Albert Colman follows trail from Kamchatka microbes into the history of Earth's atmosphere. Exotic bacteria that do not rely on oxygen may have played an important role in determining the composition of Earth's early atmosphere, according to a theory that UChicago researcher Albert Colman is testing in the scalding hot springs of a volcanic crater in Siberia. He has found that bacteria at the site produce as well as consume carbon monoxide, a...

The heat in the atmosphere of Venus, induced from a strong greenhouse warming, might actually have a cooling effect on the planet's interior. This counter-intuitive theory is based on calculations from a new model presented at the European Planetary Science Congress (EPSC) in Rome on Tuesday September 21st. "For some decades we've known that the large amount of greenhouse gases in the atmosphere of Venus cause the extreme heat we observe presently", explains Lena Noack from the German...

The next Yellowstone eruption could be similar volcanic event Millions of years ago, volcanic eruptions in North America were more explosive and may have significantly affected the environment and the global climate. So scientists report in this week's issue of the journal Nature. The researchers found the remains--deposited in layers of rocks--of eruptions of volcanoes located on North America's northern high plains that spewed massive amounts of sulfate aerosols into the atmosphere 40...

On March 20, Iceland's Eyjafjallajokull volcano woke from its nearly 200-year slumber to change the way the world viewed volcanoes forever. Bringing almost all transatlantic air travel to a halt for the first time in modern history, this volcano reminded humanity of the powers these forces of nature contain "“ and of our relative inability to understand them. Associate Professor Huiming Bao of LSU's Department of Geology & Geophysics has published research in the journal Nature...

The eruption of an Icelandic volcano that sent a huge plume of ash into the atmosphere and caused sweeping disruptions of air traffic over Great Britain and Scandinavia today will likely dissipate in the next several days, according to a University of Colorado at Boulder atmospheric scientist. Professor Brian Toon, chair of CU-Boulder's atmospheric and oceanic sciences department, said the plume created by the eruption of the Eyjafjallajokull Volcano contains tiny rock particles made up of...

The gases which formed the Earth's atmosphere - and probably its oceans - did not come from inside the Earth but from outer space, according to a study by University of Manchester and University of Houston scientists. The report published this week in the prestigious international journal 'Science' means that textbook images of ancient Earth with huge volcanoes spewing gas into the atmosphere will have to be rethought. According to the team, the age-old view that volcanoes were the source of...

Carbon dioxide completely "disappears" into the atmosphere at all other volcanoes on Earth Science has unearthed the secret to what might have been alchemy at Oldoinyo Lengai volcano in Tanzania. There, in the ancient East African Rift at a place known to local Maasai people as the Mountain of God, Oldoinyo Lengai spews forth carbon dioxide-laden lavas called carbonatites. The carbonatites line the volcano's flanks like snowballs. Oldoinyo Lengai is the only place on Earth where carbonatites...

By Jolley, David W Widdowson, Mike; Self, Stephen Abstract: Research from biological and geological sources has highlighted the role of volcanoes in the outgassing of P, and thermal fixation and subsequent atmospheric oxidation of NO^sub x^ in volcanic environments. The impact of these nutrient fluxes on biological systems has been demonstrated on present-day Hawai'i, and here we consider the impact on the plant communities within a large igneous province (LIP). The Miocene Columbia River...

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....
