Summary:
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 Mauna Loa's lava flow (November-December 10, 2022) in Hawaii, US. The map was derived from synthetic aperture radar (SAR) images on Dec. 04, 2022 by the Copernicus Sentinel-1 satellites operated by the European Space Agency (ESA). The pre-event images were taken on Nov. 10, 2022 and Nov. 22, 2022.
Suggested Use:
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 the Media reports and other images.
This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas. In this case, the damage signal is due almost entirely to new lava flows and volcanic tephra (ash) deposits near the summit of Mauna Loa that covered the surface from the start of the eruption until December 4. 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 and new lava flows, but small-scale change or partial structural damage may not be detected by this map.
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), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team. NASA's Earth Applied Sciences Disasters Program provided part of the funding.
