Kīlauea is a volcano in the Hawaiian Islands, and one of five shield volcanoes that together form the island of Hawaiʻi. The Puʻu ʻŌʻō cone has been continuously erupting in the eastern rift-zone since 1983, making it the longest rift-zone eruption of the last 200 years. Thirty-five eruptions have taken place since 1952, not including the current episode. An airborne radar developed by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has just returned to Hawaii to continue its study of Kilauea volcano, Hawaii’s current most active volcano. 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.
