Why Houston and 25 Major US Cities Are Sinking Due to Subsidence

Understanding Subsidence

• 💡 Subsidence is the slow and gradual sinking of land, often caused by excessive groundwater pumping, known as aquifer depletion.
• ⚠️ In areas like California's San Joaquin Valley, aquifer depletion led to ground sinking up to 30 feet, significantly impacting property values.

Houston's Unique Subsidence Challenges

• 🎯 Houston is identified as the fastest-sinking city in the U.S., experiencing subsidence of up to two inches per year in some areas.
• ⛽ In addition to groundwater depletion, oil and gas extraction contributes to Houston's severe subsidence problem.
• 🏗️ Uneven sinking creates significant stress on critical infrastructure, including roads and buildings.

Widespread Impact of Subsidence

• 📊 New research indicates that 25 out of 28 major U.S. cities are experiencing subsidence.
• 🌍 This phenomenon is reshaping the ground we live on and has the potential to impact infrastructure in nearly 90% of the largest cities.
• 📉 The economic consequences are substantial, with studies estimating billions in lost aggregate housing value in affected regions.
