A new study led by Virginia Tech researchers has confirmed that the Hampton Roads region in Virginia is sinking by an average of 2.3 millimeters per year, a gradual decline that has been observed since the 1970s. The study found that the sinking is caused by a combination of tectonic plate shifts and localized groundwater withdrawal, leading to increased tidal flooding, storm surges, and other impacts in low-lying areas.

Why it matters

The gradual sinking of the Hampton Roads region, when combined with rising sea levels, poses significant long-term challenges for coastal communities in the area, including increased flooding, storm damage, and infrastructure issues. The new data will help local and state leaders plan for future mitigation and adaptation efforts.

The details

The study, recently published in Nature Scientific Review, found that the entire Chesapeake Bay region is experiencing varying degrees of "subsidence," or the gradual sinking of land. Researchers determined that the two main factors behind this are the shifting of tectonic plates, which is unavoidable, and localized groundwater withdrawal. While the exact contribution of each factor is unclear, the impacts are undeniable, including tidal flooding, storm surges reaching further inland, and more frequent flooding in low-lying areas.

• The study's findings were recently published in February 2026.
• Researchers have been tracking the gradual sinking of the Hampton Roads region since the 1970s.

What’s next

City leaders in Hampton Roads said the sinking has not yet reached a threat level, but the new data will allow them to calibrate models and make plans for future flood prevention efforts.
