Major US Cities Sinking Due to Urbanization
Tap title to read story
A new satellite study reveals that 28 major US cities are sinking due to urbanization, drought, and rising sea levels. At least 20% of each city's land subsided between 2015 and 2021, with 25 cities showing subsidence in at least 65% of their land. Cities like Houston, Dallas, and New York are experiencing particularly rapid sinking rates, exceeding 2 millimeters per year. This uneven subsidence risks infrastructure damage, including cracking in roads and buildings, and increased flooding. Researchers suggest solutions like reduced groundwater extraction and improved drainage systems, highlighting the need for proactive urban planning.
