Land subsidence threatens US critical infrastructure: study

Critical infrastructure on the US East Coast faces an increasing risk of failure due to annual land subsidence, which raises the likelihood of flooding and structural damage, according to a study published in the PNAS Nexus journal. The research reveals that roughly 50% of infrastructure in cities such as New York, Baltimore, and Norfolk is exposed to subsidence rates of between 1 and 2mm per year. The study emphasises the need for a new approach to tackle escalating risks from climate change and calls for comprehensive community and infrastructure resilience planning.
