..And for fun, check out this animated map of twitter reports as the earthquake occurred.
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?

Today, NASA and the Space Agency of Argentina launched the Aquarius Spacecraft, a mission to map salinity patterns in the ocean. If all goes well, it will quickly surpass the amount of data gathered from ships over the past century in mere months.
Salinity data will enhance the understanding of ocean circulation and how it responds to freshwater inputs (like massive glacial melting) and global climate changes. Good stuff - Link |
