USA Hurricane Ida: Damage Proxy Map, Aug 2021

# Bahamas - ARIA Damage Proxy Map v0.3 The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of the Bahamas that are likely damaged (shown by red and yellow pixels) as a result of Hurricane Dorian that made a landfall as Category 5 storm Sunday (September 1) afternoon. The map was derived from synthetic aperture radar (SAR) data acquired around 7pm (local time) on September 2, 2019 by the European Union's Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken before (August 21, 2019) and the post-event image was acquired a day after the hurricane's landfall. The map covers an area of 176 by 170 kilometers, indicated with the big red polygon. Each pixel measures about 30 meters across. The color variation from yellow to red indicates increasingly more significant ground surface change. Media reports provided anecdotal preliminary validation. This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas and flooded areas. For example, the scattered single colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. This task was funded by NASA Disasters Program.

# Louisiana Hurricane Laura: Damage Proxy Maps, Aug 2020 The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and Caltech, in collaboration with the Earth Observatory of Singapore (EOS), produced these damage proxy maps for Louisiana Hurricane Laura (Aug 2020) from synthetic aperture radar (SAR) satellite images. Each map is a separate ZIP below with its GeoTIFF, a KMZ for Google Earth, the PNG figures and a text file describing how it was made and how to read it. ## Maps in this dataset - **ARIA-SG Damage Proxy Map: Louisiana, USA, Hurricane Laura, 1 Sep 2020, v0.4 ** - **ARIA-SG Damage Proxy Map: Louisiana, USA, Hurricane Laura, 1 Sep 2020, v0.4 ** **More map details and files:**

# ARIA Damage Proxy Map, Izmir, Turkey Earthquake The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology, both in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas that are likely damaged by the recent Mw 7.0 (October 30, 2020) earthquake beneath the Aegean Sea between Samos, Greece and Izmir, Turkey. The map was derived from synthetic aperture radar (SAR) images on October 30, 2020 by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken before (October 18, 2020 and October 24, 2020) the earthquake. The image covers an area of 337 by 175 kilometers (210 by 108 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 areas. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. This map is most sensitive to building damage, but small scale change or partial structural damage may not be detected by this map. Contains modified Copernicus Sentinel data, processed by ESA. Analyzed by the NASA-JPL/Caltech ARIA team. This task was carried out at JPL funded by NASA. The products (KMZ and GeoTIFF files) are available to download at For more information about ARIA, visit: **More map details and files:** **NOTE for KMZ users:** After opening the KMZ file, please uncheck the "Compress" option in the "Texture Colors" section in the "3D View" tab under the menu "Google Earth Pro > Preference..." (Mac) or "Tools > Options..." (Windows). After unchecking the "Compress" option, Google Earth needs to be restarted. If the Compress option is on, some red pixels may appear as greenish dull color.

# EOS-RS Damage Proxy Map: Haiti earthquake, Mw7.2, 14 August 2021, v0.8 This preliminary map shows areas which are likely damaged in west Haiti due to an Mw7.2 earthquake which occurred in the morning of 14 Aug (local time). Damage is shown by coloured pixels of 30 m in size, where yellow to red indicates increasingly significant ground surface change before and after the event. The map extents are indicated by the white polygon. This map should be used as a guidance to identify damaged areas, and may be less reliable over vegetated areas. Scattered pixels over vegetated areas may be false positives, and a lack of coloured pixels over vegetated areas may not mean no damage. This map is most sensitive to building damage and liquefaction, but small scale change or partial structural damage may not be detected. Derived from synthetic aperture radar data acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) up to August to 15 August 2021. Analysed by the EOS-RS team at the Earth Observatory of Singapore (EOS) in collaboration with NASA-JPL and Caltech. More map details and files at: **More map details and files:**

# EOS-RS Damage Proxy Map: Montana (Yellowstone National Park), USA, Floods, 15 Jun 2022, v0.9 The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged in the areas in Montana, United States due to floods caused by heavy rainfall and snowmelt. This map was derived from synthetic aperture radar (SAR) images acquired by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA) before (15 Feb 2022 - 3 Jun 2022) and after (15 Jun 2022) the event. The image covers an area indicated by the large white polygon. Each pixel measures about 30 meters across. The colour variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with high-resolution optical imagery and media reports. This map could be used as a guidance to identify damaged areas, and may be less reliable over vegetated areas (such as landslides in vegetated slopes). Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage. Sentinel-1 data were accessed through the Copernicus Open Hub. This map contains modified Copernicus Sentinel data (2022), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) in collaboration with NASA-JPL and Caltech. **More map details and files:** **More map details and files:**

# EOS-RS Damage Proxy Map: Ecuador, Earthquake, 19-26 Mar 2023, v0.8 The Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS) created this preliminary Damage Proxy Map (DPM) depicting areas that are likely damaged in southern Ecuador and northern Peru due to the M6.8 earthquake that occurred on 18 Mar 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 (7 Nov 2022 to 14 Mar 2023) and after (19-26 Mar 2023) the event. The image covers an area indicated by the large white polygon. Each pixel measures about 30 meters across. The colour variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with media reports. This map could be used as a guidance to identify damaged areas, and may be less reliable over vegetated areas. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage. Some pixels may be due to changes in vegetation cover. The product contains modified Copernicus Sentinel data (2022-2023), processed by ESA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS). **More map details and files:** **More map details and files:** **Credits:** Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Contains modified Copernicus Sentinel data (2022-2023).
