The National Mall in Washington, District of Columbia — The American Northeast (Mid-Atlantic)
—Earthquake of August 23, 2011 —
On August 23, 2011, a 5.8 magnitude earthquake occurred 84 miles southwest of Washington, D.C. As the earth shook, the Washington Monument sustained significant damage to many of its marble and granite blocks.
Although the monument remains structurally sound, internal and external stone damage was discovered in many areas. Most occurred in the top fifty feet of the monument, the pyramidion, which suffered cracks to marble panels, tie beams, and rib bearing haunches, as well as displacement of rib stones. Emergency teams waterproofed cracks and removed loose stone for safety.
