NASA radar demonstrates ability to foresee sinkholes
(Phys.org) —New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, La., that year.
Earth's mantle plasticity explained
Earth's mantle is a solid layer that undergoes slow, continuous convective motion. But how do these rocks deform, thus making such motion possible, given that minerals such as olivine (the main constituent ...
Researchers calculate how river networks move across a landscape
Large river networks—such as those that funnel into the Colorado and Mississippi rivers—may seem to be permanent features of a landscape. In fact, many rivers define political boundaries that have been ...
Activity more than location affects perception of quakes
Scientists rely on the public's reporting of ground shaking to characterize the intensity of ground motion produced by an earthquake. How accurate and reliable are those perceptions?
Urbanization exposes French cities to greater seismic risk
French researchers have looked into data mining to develop a method for extracting information on the vulnerability of cities in regions of moderate risk, creating a proxy for assessing the probable resilience of buildings ...
TRMM satellite images show California soaker moved eastward
The Tropical Rainfall Measuring Mission or TRMM satellite provided a look at the rainfall associated with the large storm system that brought soaking rains to California on Feb. 28 and Mar. 1. Satellite imagery ...
Engineers taking Earth-based measurements to calibrate NASA's newest weather satellite
(Phys.org) —After Atlanta was paralyzed by a rare snowstorm, many fingers were pointed assigning blame for the resulting traffic catastrophe, including at least one aimed at imprecise weather predictions.
