Research shows reservoirs of silica-rich magma, which causes the most explosive volcanic eruptions, can persist in Earth’s upper crust for hundreds of thousands of years without erupting.
Earth scientists are laying plans for a two-year study designed to develop a better understanding of how Mount St. Helens gets its supply of volcanic magma.
New ice core research shows that the warming that ended the last ice age in Antarctica began at least 2,000 years earlier than previously thought.
UW researchers have discovered a high-performance polymer that could make inexpensive, organic solar cells competitive with silicon-based cells.
For the first time, scientists have direct geochemical evidence that the 150-mile long Tsangpo Gorge, possibly the world’s deepest, was the conduit by which megafloods from glacial lakes, perhaps half the volume of Lake Erie, drained catastrophically through the Himalayas when their ice dams failed during the last 2 million years.
Swarms of small earthquakes before a volcanic eruption can come in such rapid succession that they create a signal called harmonic tremor. A new eruption analysis from Alaska’s Redoubt Volcano shows the harmonic tremor glided to higher frequencies, then stopped abruptly just before six eruptions in 2009.
