For many years, most scientists studying Tibet have thought that a very hot and very weak lower and middle crust underlies its plateau, flowing like a fluid. Now, a team of researchers at the California Institute of Technology (Caltech) is questioning this long-held belief and proposing that an entirely different mechanism is at play.

Average winter temperatures in northern Europe are at least 10 degrees Fahrenheit warmer than similar latitudes on the northeastern coast of the United States and the eastern coast of Canada. The same phenomenon happens over the Pacific, where winters on the northeastern coast of Asia are colder than in the Pacific Northwest. Researchers at Caltech have now found a mechanism that helps explain these chillier winters—and the culprit is warm water off the eastern coasts of these continents.

The number of large destructive earthquakes in 2010, plus a flurry of medium magnitude quakes in California, led many people to ask, Are we in a period of heightened temblor activity, and is it likely to continue? E&S sat down with Hiroo Kanamori, the Smits Professor of Geophysics, Emeritus, and Joe Kirschvink, the Van Wingen Professor of Geobiology, to hear their thoughts.

About 450 million years ago, Earth suffered the second-largest mass extinction in its history—the Late Ordovician mass extinction, during which more than 75 percent of marine species died. Exactly what caused this tremendous loss in biodiversity remains a mystery, but now a team led by researchers at Caltech has discovered new details supporting the idea that the mass extinction was linked to a cooling climate.
