NASA completes study of Louisiana Gulf Coast Levees and Wetlands

Pasadena, CA – NASA recently completed an intensive study of Louisiana Gulf Coast levees and wetlands, making measurements with three advanced imaging instruments on three research aircraft.

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.

Pasadena, CA – A NASA-developed airborne imager called a synthetic aperture radar took a detailed look at volcanoes in Central and South America during an Earth science study in late April and early May 2014.

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.

NASA study shows Baja Earthquake caused quiet motion in Southern California faults

Pasadena, CA – A new NASA study finds that a major 2010 earthquake in northern Mexico triggered quiet, non-shaking motions on several Southern California faults that released as much energy as a magnitude 4.9 to 5.3 earthquake.

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.

NASA Radar Demonstrates Ability to Foresee Sinkholes

March 7, 2014 |

Washington, DC – 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.

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.

Such data may someday help foresee sinkholes. (On Wings of Care)
