Synthetic aperture radar interferometry of Okmok volcano , Alaska : Radar observations

  title={Synthetic aperture radar interferometry of Okmok volcano , Alaska : Radar observations},
  author={Zhong Lu and Drrte Mann and Jeffrey T. Freymueller},
ERS-1/ERS-2 synthetic aperture radar interferometry was used to study the 1997 eruption of Okmok volcano in Alaska. First, we derived an accurate digital elevation model (DEM) using a tandem ERS-1/ERS-2 image pair and the preexisting DEM. Second, by studying changes in interferometric oherence we found that the newly erupted lava lost radar coherence for 5-17 months after the eruption. This suggests changes in the surface backscattering characteristics and was probably related to cooling and… CONTINUE READING
