Washington Monument earthquake damage and repairs (2011–2014)

On August 23, 2011, a 5.8 magnitude earthquake centered in Virginia caused cracks and displaced stones in the Washington Monument, prompting its closure on safety grounds. The National Park Service undertook structural inspections and repairs, and the Monument remained closed for restoration work before reopening to the public in 2014. The event is a documented instance of seismic damage to a major Washington, D.C. landmark.
