Date of Image: 2/10/2023 Date of Next Image: Unknown Summary: 2/10/2023 (ARIA, Copernicus Sentinel-1) The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology in Southern California created this Damage Proxy Map (DPM) depicting areas that are likely damaged by the large earthquakes (Feb. 06, 2023) in Turkiye (Turkey) and Syria. The map was derived from synthetic aperture radar (SAR) images on Feb. 10, 2023 by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken from Sep. 19, 2022 to Jan. 29, 2022). Suggested Use: Standard Version: The color variation from pale yellow to red indicates increasingly more significant surface change (drop in radar reflection coherence). Preliminary validation was done by comparing with high-resolution optical imagery and media reports. NOTE: This damage proxy map could be used as a guidance to identify damaged areas, and may be less reliable over vegetated and mountainous areas. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage. Satellite/Sensor: Copernicus Sentinel-1 Synthetic Aperture Radar (SAR) Resolution: 30 meters Credits: Sentinel-1 data were accessed through the Copernicus Open Hub and the Alaska Satellite Facility server. The product contains modified Copernicus Sentinel data (2022-2023), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team in collaboration with Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS).

# ARIA DPM Sentinel-1 v1.0, Hurricane Ida The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology in Southern California, in collaboration with the Earth Observatory of Singapore (EOS), created this Damage Proxy Map (DPM) depicting areas that are likely damaged by the Hurricane Ida (August 29, 2021) in central and western Louisiana, United States. The map was derived from synthetic aperture radar (SAR) images on Sep 03, 2021 by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken before (Aug 10, 2021 and Aug 22, 2021) the hurricane hit land. The image covers an area of 337 by 250 kilometers (210 by 155 miles), shown by the large red polygon. Each pixel measures about 30 meters across. The color variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with the Media reports. This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated or flooded areas. For example, the scattered colored pixels over vegetated areas and flooded fields may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. Some additional false positives in the middle of the image are likely due to the stitching of Sentinel-1 frames as a thin line running across the map at a ENE-WSW angle. This map is most sensitive to building damage, but small-scale change or partial structural damage may not be detected by this map. Sentinel-1 data were accessed through the Copernicus Open Hub and the Alaska Satellite Facility server. The product contains modified Copernicus Sentinel data (2021), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team and EOS team. Part of the funding was provided by NASA's Earth Applied Sciences Disasters Program.

Google Earth may need to be restarted afterwards.

Date of Image: 2/8/2023, 2/9/2023, 2/10/2023 Date of Next Image: Unknown Summary: 2/8/2023 (EOS-RS, JAXA ALOS-2) The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged in Turkiye (Turkey) and Syria due to the M7.8 and M7.5 earthquakes that occurred on 6 Feb 2023. This map was derived from synthetic aperture radar (SAR) images acquired by the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) before (7 Apr 2021 and 6 Apr 2022) and after (8 Feb 2023) the event. 2/9/2023 (EOS-RS, Copernicus Sentinel-1) The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged in Turkiye (Turkey) and Syria due to the M7.8 and M7.5 earthquakes that occurred on 6 Feb 2023. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellite operated by the European Space Agency (ESA) before (12 Oct 2022 to 28 Jan 2023) and after (9 Feb 2023) the event. 2/10/2023 (EOS-RS, Copernicus Sentinel-1) The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged in Turkiye (Turkey) and Syria due to the M7.8 and M7.5 earthquakes that occurred on 6 Feb 2023. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellite operated by the European Space Agency (ESA) before (13 Oct 2022 to 29 Jan 2023) and after (10 Feb 2023) the event. Suggested Use: Standard Version: The color variation from pale yellow to red indicates increasingly more significant surface change (drop in radar reflection coherence). Preliminary validation was done by comparing with high-resolution optical imagery and media reports. Color Vision Deficiency (CVD) Version: The color variation from light blue to dark blue indicates increasingly more significant surface change. Preliminary validation was done by comparing with high-resolution optical imagery and media reports. NOTE: This damage proxy map could be used as a guidance to identify damaged areas, and may be less reliable over vegetated areas. The time intervals between the ALOS-2 acquisitions are up to a year apart, so the accuracy of the DPM may be lower in areas of vegetation, such as in the mountains. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage.
