34 million Americans are living in cities that are sinking, a Columbia University study recently found. By using satellite technology and measuring surface changes between 2015 and 2021, researchers discovered that Houston, Fort Worth, and Dallas…all Texas cities…are sinking the fastest. Nationally, San Antonio, Austin, and Houston contain 82% of building at high risk. Why are cities sinking? Texas may be at risk due to increased water demands and groundwater depletion. (Study Finds)
