On March 25, 1993, the magnitude 5.6 Scotts Mills earthquake damaged the dome, requiring closure for repairs. The rotunda area remained closed for approximately two years for these repairs. This "Spring Break Quake" shook the building enough to shift the statue on top and crack the dome. Additionally, the quake created a three-foot (one-meter) bulge on the west end of the building. Repairs cost $4.3 million ($  as of ) and included reinforcing the structure with additional concrete and steel bars.
