description: Date of Image: 2/8/2023 Date of Next Image: Unknown Summary: Scientists working with Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology, both in Pasadena, California, created these displacement maps with measurements of the surface displacements, in the radar line-of-sight, caused by the recent major earthquake in Türkiye, the Mw 7.8 (February 6, 2023) main shock near the city of Nurdagi followed by Mw 7.5 aftershock within 9 hours. The maps were derived from synthetic aperture radar (SAR) images from the ALOS-2 L-band operated by the Japanese Aerospace Exploration Agency (JAXA) ALOS-2 SAR satellite. The team computed the interferometric difference (interferogram or interferometric SAR) and pixel offset tracking between the post-event image acquired on February 8, 2023 with a pre-event image acquired on April 6, 2022, on the ALOS-2 descending (satellite moving south) track 78. The interferometric SAR (InSAR) measures the component of surface displacement in the line-of-sight (LOS) between the ground and the satellite, which is at an angle of about 30 degrees from the vertical up and to the east. NOTE: The line-of-sight displacement (LOS) measurement is relative, and the dataset has not been calibrated to any ground location so there is a bias of the reference level, which is unknown. This data has not yet been validated. This displacement map should be used as guidance to identify areas of significant ground displacement, and may be less reliable over snow-covered and vegetated areas. Suggested Use: Displacement (UNW): Red colors indicate increasing displacement towards the East, while the Blue areas indicate increasing displacement towards the West Along Track Displacement (AZI): Red colors indicate increasing displacement towards the South-Southwest, while the Blue areas indicate increasing displacement towards the North-Northeast Across Track Displacement (RNG): Red colors indicate increasing…
