Topic: C-20A jetWritten by Alan Buis
NASA instruments fly over the Gulf Coast one to three times per year to keep consistent records of ground subsidence — the gradual sinking of an area of land — which can compromise the integrity of roads, buildings and levee systems. Scientists also closely monitor vegetation changes in the coastal wetlands to better understand how to preserve them. ![]() UAVSAR image of Wax Lake Delta at low tide captured during a flight on May 5, 2015. Research on the delta’s growth through natural sedimentation processes can aid future work on restoring deltas worldwide. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA Earth Science study uses UAVSAR imager to take close look at Volcanoes in Central, South AmericaWritten by Alan Buis
The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, was flown on NASA’s C-20A. The 29-day deployment ended May 6th when the aircraft returned to its base in Palmdale, California, after 19 flights totaling 97 hours in the air. ![]() This false-color image of Peru’s Ubinas volcano was acquired on April 14, 2014, by NASA’s Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR.

NASA study shows Baja Earthquake caused quiet motion in Southern California faultsWritten
The quiet motion associated with the widely felt, magnitude 7.2 earthquake centered in northern Baja California in Mexico, in April 2010 was discovered in before-and-after radar images of the region made by a NASA airborne instrument that produces extremely accurate maps of Earth motions. ![]() UAVSAR measurements north of the 2010 El Mayor-Cucapah earthquake, which scientists have learned was followed by quiet movement on faults in California. Inset map shows the region on the California-Mexico border. (NASA/JPL/USGS/California Geological Survey/Google) «Read the rest of this article» Sections: Technology | No Comments
NASA Radar Demonstrates Ability to Foresee Sinkholes
The findings suggest such radar data, if collected routinely from airborne systems or satellites, could at least in some cases foresee sinkholes before they happen, decreasing danger to people and property. ![]() Aerial photo of a 25-acre sinkhole that formed unexpectedly near Bayou Corne, La., in Aug. 2012. New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of the sinkhole before it collapsed and forced evacuations. Such data may someday help foresee sinkholes. (On Wings of Care) «Read the rest of this article» Sections: Technology | No Comments
