An array of detectors, part of the USArray/EarthScope Facility, picked up the microscopic movement of the earth in the wake of the August 23, 2011, Mineral, Virginia quake. Though I didn't notice the 5.9 quake, detectors as far as California and Canada measured displacement down to microns. Check out the ripples the Array picked up and where they concentrated. Why does movement continue in the New Madrid area after much of the movement has abated? Or for that matter, why are the detectors so dense throughout the plains?
