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 7.8 (February 6, 2023) main shock near the city of Nurdagi followed by Mw 7.5 aftershock within 9 hours. <\/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) and pixel offset tracking between the post-event image acquired on February 10, 2023 with a pre-event image acquired on January 29, 2023, on the Sentinel-1 ascending (satellite moving north) track 21. 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 east. The area close to the epicenter of the Mw 7.8 earthquake moved east and up (positive in the radar line-of-sight on this track).<\/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>

Across Track Displacement (RNG): <\/SPAN>Red colors indicate increasing displacement towards the East, while the Blue areas indicate increasing displacement towards the West<\/SPAN><\/P>

Along Track Displacement (AZI): <\/SPAN>Red colors indicate increasing displacement towards the South, while the Blue areas indicate increasing displacement towards the North<\/SPAN><\/P>

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