Miami's Trump International Beach Resort Is Slowly Sinking Into the Ground

On a half-mile of sand in Sunny Isles Beach, Florida, some of the most expensive apartments in America stand thirty and forty stories tall — the Trump International Beach Resort, the Trump Towers, the Porsche Design Tower with the car elevator. Between 2016 and 2023, European radar satellites measured the roofs of these buildings down to fractions of an inch. Thirty-five of them were going down. Not falling — sinking. And nearly 70% of the coastal buildings the scientists examined were subsiding, on ground where a single apartment can cost millions. This is the full story of Sunny Isles Beach: how a strip of two-story motels became one of the richest skylines in the country, why the porous limestone and hidden sand beneath it can't be seen from the street or from space, how the 2021 Surfside collapse that killed 98 people rewrote Florida law and handed condo owners bills some can't pay, and why a building here can start sinking because of someone else's foundation next door. The towers still look the same from Collins Avenue. But the trophies have quietly become questions. ⚠️ Note: the buildings named here are not known to be unsafe, and the study's authors did not claim any of them are in danger. This is a documentary about the geology, the economics, and the public satellite research — not a safety warning about any specific home. 🏙️ Should the city stop approving new towers until the ground under the old ones is understood — even if the skyline stops growing? Or did these owners get exactly what they paid for when they bought a view on a sandbar? Let me know in the comments.
