Ancient Andes suggest way to predict quakes
MONASH (AUS) — Scientists are a step closer to predicting when and where earthquakes will occur after taking a fresh look at the formation of the Andes, which began 45 million years ago. Continue…

New view of California’s tectonic plates
BROWN (US) — The highest resolution picture ever obtained of southern California’s lithosphere shows its thickness differs markedly, offering new insight into how rifting shaped the area’s terrain. (more…)

Mexico quake’s path veered from norm
CALTECH (US) — The El Mayor-Cucapah earthquake that struck Baja California in April 2010 took a divergent route, causing a fault line that remained straight on the surface but was warped and complicated at depth. (more…)

Japan’s earthquake was a one-two punch
STANFORD (US) — The magnitude 9.0 earthquake and resulting tsunami that struck Japan in March were generated on a fault that ruptured in a flip-flop motion. (more…)

New data: How earth moved under Japan
CALTECH (US) — The first large observational study of Japan’s magnitude 9.0 earthquake in March is yielding surprising findings about fault slip and stress accumulation in the Japan Trench. (more…)

Computer models shake up plate tectonics
CALTECH / U. TEXAS-AUSTIN (US)—New computer algorithms allow for the first time simultaneous modeling of the earth’s mantle flow, large-scale tectonic plate motions, and the behavior of individual fault zones. The result is an unprecedented view of plate tectonics and the forces that drive it. (more…)

Mantle flow can move mountains
USC (US)—If tectonic plate collisions cause volcanic eruptions, why do some volcanoes erupt far from a plate boundary? (more…)

Computer model shows speeding mantle
UC DAVIS (US)—The Earth’s mantle flows far more rapidly around a sinking tectonic plate than previously thought, according to new computer modeling. The findings could change the way that we think about plate tectonics and the amount of energy available for earthquakes. (more…)

Aseismic creep may lower earthquake hazard
CALTECH (US)—Using data from GPS stations, researchers analyzed plate slippage following the magnitude 8.0 earthquake that struck in Central Peru in August 2007, killing more than 500 people. What the team discovered ran contrary to long-held assumptions about plate movement in the area—and suggests a model for predicting earthquake patterns. (more…)

Predicting Earth’s tectonic dance
RICE (US)—A research team has put the finishing touches on a 20-year labor of love: a precise description of the relative movements of the interlocking tectonic plates that account for about 97 percent of Earth’s surface. (more…)
