ABC News - Another part of the US sinking?
A new study from the University of Miami highlights that at least 35 coastal buildings in South Florida are experiencing subsidence, or sinking. This phenomenon is not isolated to Florida; cities like New Orleans, Mexico City, and Venice also face similar issues. The study follows the 2021 collapse of a condo tower in Surfside, Florida, although subsidence was not a factor in that disaster. However, the building next door was found to be sinking. Other cities like New York and areas in California are also experiencing sinking due to factors like the weight of buildings and groundwater pumping, respectively. In New York, buildings are sinking at a rate of 1 to 4 millimeters per year, potentially increasing flood risks as sea levels rise. In California's San Joaquin Valley, excessive groundwater pumping has caused land to sink by up to one foot per year, damaging infrastructure and costing millions in repairs. Despite these findings, researchers suggest that the immediate concern in South Florida is the increased risk of flooding rather than the sinking itself.
Key Points:
- 35 coastal buildings in South Florida are sinking due to subsidence.
- Sinking is a global issue, affecting cities like New Orleans, Mexico City, and Venice.
- New York City buildings are sinking 1-4 mm per year, increasing flood risks.
- California's San Joaquin Valley sinks up to one foot per year due to groundwater pumping.
- Immediate concern in South Florida is higher flood risk, not the sinking itself.
