π𫨠Massive can trigger long-term land sinking and affect π regional relative sea-level projections in Southeast Asia, found an international study led by earth scientists from Earth Observatory of Singapore and NTU Asian School of the Environment. If this post-earthquake ground movement is not factored into modelling, risks in low-lying areas could be underestimated.
Published in Nature Portfolio's journal Communications Earth & Environment, the study discovered that a weak layer of hot rock in the upper mantle beneath the Sumatran backarc β the region behind Sumatra's chain of volcanoes β slowly deforms after major earthquakes. This causes the ground above to keep shifting and sinking for decades, even in places more than 600km from the earthquake epicentre.
The findings could help π improve future sea-level projections and support better coastal planning and flood risk assessments across Southeast Asia. https://ntu.sg/Earthquakes-Sea-levelProjectionsStudy
