Scientific deep sea drilling vessel Chikyu sets a world new record by drilling down and obtains rock samples from deeper than 2,111 meters below the seafloor

The most-studied mass extinction in Earth history happened 65 million years ago and is widely thought to have wiped out the dinosaurs. New research indicates that a separate extinction came shortly before that, triggered by volcanic eruptions

Three of the largest and deadliest earthquakes in recent history occurred where earthquake hazard maps didn't predict massive quakes. A University of Missouri scientist and his colleagues recently studied the reasons for the maps' failure to forecast thes

Scientists at Scripps Institution of Oceanography at UC San Diego have come a step closer to deciphering some of the basic mysteries and mechanisms behind earthquakes and how average-sized earthquakes may evolve into massive earthquakes

Uranium floats in Earth's oceans in trace amounts of just 3 parts per billion, but it adds up. Combined, our oceans hold up to 4.5 billion tons of uranium -- enough to potentially fuel the world's nuclear power plants for 6,500 years

A new study has successfully reconstructed temperature from the deep sea to reveal how global ice volume has varied over the glacial-interglacial cycles of the past 1.5 million years

A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable

As sulfur cycles through Earth's atmosphere, oceans and land, it undergoes chemical changes that are often coupled to changes in other such elements as carbon and oxygen

Researchers expect a moderate geomagnetic storm to strike Earth this weekend, causing satellite glitches, power disruptions and colorful auroras possibly as far south as Washington D.C.

Researchers from Germany, Finland, Scotland, and Switzerland examined tree-ring density profiles in trees from Finnish Lapland. In this cold environment, trees often collapse into one of the numerous lakes, where they remain well preserved for thousands o
