Making an explosive double date with Russian volcanoes
Two French scientists are traveling to one of the remotest places on Earth, the Kamchatka peninsula, to piece together the complex life story of two volcanoes. Kamchatka is a unique site for studying how volcanic cycles shaped the landscape of the early Earth.

Eruptive characteristics of Oregon's Mount Hood analyzed
A new study has found that a mixing of two different types of magma is the key to the historic eruptions of Mount Hood, Oregon's tallest mountain, and that eruptions often happen in a relatively short time -- weeks or months -- after this mixing occurs. It will help scientists better understand the nature of Mount Hood's past and future eruptions, as well as other volcanoes that erupt by similar mechanisms. This includes a large number of the world's active volcanoes.

Accepted theory explaining frequent eruptions at Italy?s Stromboli volcano questioned
One volcano that volcanologists believe they understand fairly well is Italy's Stromboli, which has been erupting every five to 20 minutes for thousands of years, spewing fountains of ash and magma several meters into the sky. For several decades, scientists have pretty much used one theory to explain what is causing huge amounts of gas to erupt so frequently: swimming-pool-sized bubbles that travel through a few hundred meters of molten magma before popping at the surface. But they may be wrong, according to new research.

Scientists assess impact of Icelandic volcanic ash on ocean biology
An international team of oceanographers investigating the role of iron on ocean productivity in the northerly latitudes of the Atlantic Ocean will assess the impact of ash from the recent Icelandic volcano eruption on ocean biology. The five-week expedition started out on July 4, 2010.

Volcanic ash research shows how plumes end up in the jet stream
A volcanologist has shown how the jet stream -- the area in the atmosphere that pilots prefer to fly in -- also seems to be the area most likely to be impacted by plumes from volcanic ash.
