Summary:<\/SPAN><\/P>

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 this displacement map with measurements of the surface displacements, in the radar line-of-sight, caused by the recent major earthquake in Turkey, the Mw 6.4 (February 20, 2023) main shock in the Hatay Province. <\/SPAN><\/P>

The map was derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). The team computed the interferometric difference (interferogram or interferometric SAR) between the post-event image acquired on February 21, 2023 with a pre-event image acquired on February 9, 2023, on the Sentinel-1 ascending (satellite moving north) track 14. 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 40 degrees from the vertical and slightly south of due west.<\/SPAN><\/P>

NOTE<\/SPAN>: 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.<\/SPAN><\/P>

Suggested Use:<\/SPAN><\/P>

Unwrapped Interferogram (UNW): <\/SPAN>Red colors indicate increasing displacement towards the West, while the Blue areas indicate increasing displacement towards the East<\/SPAN><\/P>

NOTE<\/SPAN>: Small vertical displacements have also occurred, but the primary surface displacements were in the horizontal plane.<\/SPAN><\/P>
