Abstract

This presentation summarizes land subsidence during 2023-2025 as reported in the news media worldwide. Subsidence during the past two years occurred from groundwater extraction, hydrocarbon production, hydrocompaction, tunneling, loading of squishy sediment, drought-induced soil shrinkage, thawing permafrost, karst, mining, and other causes. News reports described the magnitude and areal extent and damage from subsidence and its effects on infrastructure at various locations in the U.S., England, India, Iran, China, Indonesia, Vietnam, Korea, Russia, Taiwan, Brazil, and elsewhere.  Threats from land subsidence have spurred, in some cases, unusual public policy decisions and spawned a market for subsidence insurance.
