Although hydrothermally active submarine volcanoes account for much of Earth's volcanism and are mineral-rich biological hotspots, very little is known about microbial diversity in these systems.In th...
Geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone -- a layer rich in water, crystals and melted rock -- can percolate to the surface...
When dormant volcanoes are about to erupt, they show some predictive characteristics—seismic activity beneath the volcano starts to increase, gas escapes through the vent, or the surrounding ground st...

Volcanoes including Mount Hood dormant
2014/3/20
A new study suggests that the magma sitting 4-5 kilometers beneath the surface of Oregon's Mount Hood has been stored in near-solid conditions for thousands of years, but that the time it takes to liq...
Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended “volcanic winters” from gigan...
Volcanoes Cool the Tropics, Say Researchers--But Global Warming May Have Helped Override Some Recent Eruptions（图）
Volcanoes the Tropics Global Warming Some Recent Eruptions
2009/12/10
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics—but suggest that such effects may have been masked in the 20th century...
