Overview

Satellite radar observations reveal significant land subsidence effects on relative sea level in coastal Java, highlighting urgent adaptation needs.

Key Points

  • The aim is to assess land subsidence on Java Island and its contributions to relative sea level rise.
  • Utilized satellite radar observations for high-resolution land subsidence assessment.
  • Employed machine learning spatiotemporal clustering for analysis.
  • Constructed virtual tide gauges at 5-km intervals along the northern coastline.
  • Identified land subsidence rates ranging from 1 to 15 cm/year in several coastal cities.
  • Dominant subsidence mechanisms attributed to resource extraction across different geological settings.
  • Projected that subsidence will heavily influence relative sea level budgets along over 75% of the coast for the next 25 years.
