Summary:
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and California Institute of Technology created the Damage Proxy Map (DPM1) depicting areas that are likely damaged in Hawaii in the U.S. due to Wildfire in early August 2023. The detail on the PNG image shows the extreme devastation of Lahaina, Maui. This map was derived from synthetic aperture radar (SAR) images acquired by the ALOS 2 satellites operated by the Japan Aerospace Exploration Agency (JAXA) in July 17 2022, June 18 2023, and August 13 2023.
Suggested Use:
The color variation from pale yellow to red indicates increasingly more significant surface change (drop in radar reflections). Preliminary validation was done by comparing with the Media reports and other images.
This damage proxy map should be used as guidance to identify damaged areas or areas affected by flood 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.
Satellite/Sensor:
Japan Aerospace Exploration Agency (JAXA) ALOS-2

The product contains modified ALOS-2 data (2022-2023), processed by JAXA and analyzed by the NASA-JPL/Caltech ARIA team. NASA's Earth Applied Sciences Disasters Program provided part of the funding.
