Sinking Cities: Why Parts of Phoenix—and Much of Urban America—Are Slowly Dropping
A new study confirms Phoenix and 27 other U.S. cities are sinking—putting millions of people and buildings at long-term risk.
Phoenix is sinking. Not metaphorically, but literally. According to a 2025 study published in Nature Cities, Arizona’s capital is subsiding at an average rate of 0.8 millimeters per year, with some areas dropping by up to 2 centimeters annually. While that might sound minor, the implications are anything but.
The study, which analyzed satellite data across 28 major U.S. cities, revealed a troubling trend: every single city examined is experiencing some form of land subsidence. And the causes are largely human-driven.
📉 What’s Happening Beneath Phoenix?
The ground beneath Phoenix is slowly compacting due to a combination of natural and human-induced factors. Chief among them is groundwater depletion. Over the past century, large-scale pumping of underground aquifers caused the soil above to compress. While Arizona implemented the Groundwater Management Act in 1980, and water use has since stabilized, the lingering impact of past overuse remains.
Some areas in the Phoenix metro region have already experienced up to 18 feet of subsidence over the last 40 years, and the newly published data shows that areas housing 1.4 million people and 113,000 buildings remain at moderate to high risk of structural damage.
🌆 Sinking Cities Across the U.S.
Phoenix isn’t alone. The Nature Cities study revealed that nearly 34 million Americans live on land that is subsiding, and over 29,000 buildings nationwide sit in zones of high or very high risk.
Here are some key findings from other cities:
Houston, TX is the most affected, with 42% of its area sinking more than 5mm/year and localized zones dropping up to 5 cm annually. Dallas–Fort Worth, New York City, Chicago, Los Angeles, and Denver are also seeing significant ground shifts. Even cities you might not expect—Portland, Boston, and Philadelphia—are experiencing measurable sinking, largely due to natural geologic changes or compaction from development on soft soils.
🛠️ What Causes Subsidence?
There’s no single cause, but several primary drivers are contributing:
Groundwater Overuse: This is the dominant factor in most regions, especially in arid and agricultural areas. Oil and Gas Extraction: Particularly in Texas, removing underground fossil fuels causes the surface to sink. Post-Ice Age Rebound Effects: In northern cities like Chicago and New York, the land is still adjusting from glacial movement thousands of years ago. Urbanization: The weight of skyscrapers, concrete, and infrastructure can compress soft soils underneath. Landfill & Soil Compaction: Areas built on old lakes, wetlands, or landfills—common in coastal cities—are inherently less stable.
⚠️ What’s at Risk?
The consequences of even slow land subsidence can be serious:
Building damage: Foundations can crack, tilt, or become unstable. Infrastructure stress: Roads, pipelines, and electrical lines can be misaligned or fractured. Flood risk: As land sinks, especially in coastal cities, the risk of storm surge and sea-level rise intensifies. Water infrastructure: Subsidence can affect aquifer storage and groundwater recharge.
✅ What Can Be Done?
While stopping subsidence entirely is nearly impossible, smart urban planning and resource management can mitigate the damage:
Limiting groundwater use through stricter regulation and conservation. Investing in resilient infrastructure designed to adapt to ground shifts. Monitoring subsidence hotspots with regular satellite data. Educating the public and developers on long-term land risks before building.
🧭 Final Thoughts
Phoenix’s slow descent is a reminder that cities are not static—they live, breathe, and shift over time. As climate change and population pressures increase, the invisible motion beneath our feet demands more attention. Cities that plan for it now will stand taller in the decades to come—even if the ground beneath them doesn’t.

Travel Advisory
Traveling to Mexico this spring? Here’s what to know about current advisories
Traveling to Mexico this spring? Visitors should be aware of state-specific travel advisories, as safety concerns in one region do not affect major resort areas like Cancun and Los Cabos, currently rated Level 2, which encourages increased caution. Monitoring official updates is essential for informed travel decisions amidst evolving conditions.

Traveling to Mexico this spring? Here’s what to know about current advisories
(Tiffany Miller for ALG Vacations) For some travelers counting down to spring break, recent headlines about violence in parts of Mexico have sparked a new question: Should I cancel my trip? Travel advisors say they are seeing a surge in calls and emails from clients trying to determine whether developments in one region affect major resort areas elsewhere.
The questions follow several days of unrest in parts of Mexico after security operations targeting organized crime leaders prompted temporary flight disruptions and shelter-in-place guidance for U.S. government personnel in areas including Puerto Vallarta and Guadalajara. In this article, ALG Vacations explains what current travel advisories mean for spring break travelers heading to Mexico.
The U.S. State Department evaluates Mexico state by state, not as a single destination, and advisory levels vary by region. Many major beach destinations, including Cancun, Riviera Maya, Tulum and Los Cabos, are currently under a Level 2 advisory, which encourages travelers to exercise increased caution. It does not discourage travel.
Part of the confusion stems from geography. Puerto Vallarta, on the Pacific coast, is roughly 1,300 miles from Cancun and the Riviera Maya on the Caribbean side, about the distance between New York and Miami. Because advisories are assigned state by state, developments in one region do not automatically alter another.
In recent days, that uncertainty has translated into additional inquiries about whether specific resort areas are experiencing disruptions. U.S. Embassy security alerts issued this week indicate that temporary shelter-in-place guidance affecting Puerto Vallarta was lifted and that flight operations resumed. The advisory level for the Mexican state of Quintana Roo remains unchanged.
Some clients are asking about alternatives, advisors say, but many are continuing with their plans after reviewing official updates. Travel patterns often shift in response to breaking headlines, they add, before stabilizing as clearer information becomes available.
The State Department assigns travel advisories on a four-tier scale ranging from Level 1, exercise normal precautions, to Level 4, do not travel. While Level 2 encourages increased awareness, Level 3 and Level 4 carry stronger language discouraging or restricting travel.
Advisories are reviewed regularly and can be updated as conditions evolve. The State Department’s Mexico advisory page breaks down conditions by state, reflecting the country’s federal structure rather than issuing a single national designation. Travelers can also enroll in the State Department’s Smart Traveler Enrollment Program, which provides real-time security updates and allows U.S. officials to contact citizens in an emergency.
Embassy notices state that airports, hotels and tourism services in Quintana Roo are operating normally. Security conditions across Mexico vary widely by state, with some regions carrying higher advisories and others designated Level 1. Most destinations popular with U.S. travelers are currently classified as Level 2.
As spring break approaches, advisors say informed decision-making depends on reviewing the advisories assigned to a specific destination and monitoring official updates, rather than reacting to national headlines alone. Travel decisions ultimately depend on individual comfort levels, they add, but advisory levels are assigned regionally and should be evaluated accordingly.
