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…)
