Hawaii Islands Sinking Faster in Some Areas, Increasing Flood Risk.

A recent study led by researchers at the University of Hawaii at Mānoa has found that certain areas of the Hawaii Islands are sinking faster than others, increasing the flood risk to infrastructure, businesses, and communities in low-lying areas, particularly in urban areas of Oahu. The study highlights the importance of considering subsidence in assessments of future flood exposure, as areas sinking rapidly will experience sea level rise impacts sooner than previously estimated. The research team analyzed satellite radar data and developed a digital elevation model to model how sea level rise and ongoing subsidence will worsen future flooding, emphasizing the need for accurate data to inform decision-making and improve flood exposure assessments and infrastructure resilience in Hawaii.
