Sentinel 1a InSAR image of the Chile Earthquake 1.4 m of range - PowerPoint PPT Presentation

Sentinel 1a InSAR image of the Chile Earthquake 1.4 m of range change collected 12 h after mainshock GPS observed ionospheric signal from both the earthquake and tsunami Tsunami-wave-generated airglow perturbations indicate increased


  1. Sentinel 1a InSAR image of the Chile Earthquake 1.4 m of range change collected 12 h after mainshock

  2. GPS observed ionospheric signal from both the earthquake and tsunami

  3. Tsunami-wave-generated airglow perturbations indicate • increased amplitudes by factor of 2 to 4 SABER scans* • multi-peak structures Multiple peak Multiple peak Before arrival of tsunami wavefront indicate • smaller amplitudes and JPL Ionosphere Nat-Haz Team • smooth profiles *Courtesy of NASA’s TIMED/SABER Team
