Interferometry Study of Hawaiian Volcano10/01/2012 |
| An airborne radar developed by NASA's Jet Propulsion Laboratory, USA, has returned to Hawaii to continue its study of the Kilauea volcano, currently Hawaii's most active volcano. The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, which was mounted in a pod under NASA's G-III research aircraft from NASA's Dryden Flight Research Center, USA, returned to Hawaii's Big Island on 7th January 2012. The one-week-long airborne campaign will help scientists better understand processes occurring under the Earth's surface at Kilauea. |

UAVSAR uses a technique called interferometry that sends pulses of microwave energy from the sensor on the aircraft to the ground to detect and measure very subtle deformations in Earth's surface.

The images show the east rift zone of Kilauea, about 6 miles (9.7 kilometers) from the summit caldera. Lava has been flowing from the east rift zone, the most active part of Kilauea, since 1983.

Using Total Stations for Indoor Radiation Mapping |
|
A total station can be used for many applications. Oak Ridge Associated Universities (USA) uses a total station for indoor radiation characterisation, which enables the team to better perform environmental assessments. This video shows how it is done.
