A team of researchers has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet. The geologists say that the ancient canyon—thousands of feet deep in places—effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast.

The powerful magnitude-8.6 earthquake that shook Sumatra on April 11, 2012, was a seismic standout for many reasons, not the least of which is that it was larger than scientists thought an earthquake of its type could ever be. Now, Caltech researchers report on their findings from the first high-resolution observations of the underwater temblor.

A catastrophic landslide 22,500 years ago dammed the upper reaches of northern California's Eel River, forming a 30-mile-long lake—which has since disappeared—and leaving a living legacy found today in the genes of the region's steelhead trout, according to scientists at the California Institute of Technology (Caltech) and the University of Oregon.
