Sinking Land Drives Hidden Flood Risk in One of the World's Most Populated Regions
"This study reveals a fundamental shift in how we understand coastal risk. In many parts of Java, the land itself is sinking so rapidly that it is overwhelming the effects of ocean-driven sea-level rise."
"Using satellite radar data and advanced machine learning techniques, the research team mapped land subsidence across Java in unprecedented detail, uncovering widespread and rapidly evolving ground sinking across both urban and rural areas."
Land subsidence is worsening flood risk along Java Island, Indonesia, with projections indicating that over 75% of the coastline will face subsidence-driven flood risk in 25 years. A study reveals that land sinking is outpacing ocean-driven sea-level rise, with rates reaching up to 1.5 meters per decade. This phenomenon affects major coastal cities and highlights a shift in understanding coastal risk, as the land sinking is a significant contributor to flooding hazards.
