# EOS-RS Damage Proxy Map: Efate, Vanuatu, Earthquakes, 17 Dec 2024, 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 Efate, Vanuatu due to a powerful Mw7.3 earthquake and several strong aftershocks on 17 Dec 2024. 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 (19 Aug 2024 to 5 Dec 2024) and after (17 Dec 2024) the event. The map covers an area indicated by the white polygon. Damage is shown by colored pixels of 30m in size, where yellow to red indicates increasingly significant ground surface change before and during the event. Preliminary validation was conducted using news reports and ground-level imagery and videos in selected areas. This map should be used as a guidance to identify damaged areas, and may be less reliable over vegetated or mountainous areas. Scattered pixels over vegetated or mountainous areas may be false positives, and a lack of colored pixels over such areas may not mean no damage. The product contains modified Copernicus Sentinel data (2024), 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:** **Legal Disclaimer:** **Credits:** Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Contains modified Copernicus Sentinel data (2024)

**UNOSAT code: VO20211025VUT** This map illustrates the volcanic ashfall dispersion as observed using Sentinel-2 imagery acquired on 23 October 2021, 10:00 hrs. local time over Yasur volcano on Tanna Island, Vanuatu. At the time of the acquisition, the ashfall covered about 20 km2 at the Southwestern direction of the volcanic crater. Using the building footprints of Humanitarian Open Street Map as a baseline, around 440 buildings in the cloud free zone are located within areas covered by ash and smoke, representing 3% of the total number of buildings in Tanna island. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).
