Mexico's 2017 earthquake emerged from a growing risk zone

Mexico's 2017 earthquake emerged from a growing risk zone Under Mexico, where the Cocos Plate from the Pacific Ocean slides under the North American Plate, a bending line of hills, created when the seafloor first formed, sits atop a flattened area of subduction. That newly recognized combination, scientists report, has created a fault that likely explains last September's Puebla earthquake, scientists report. http://ift.tt/eA8V8J
