The Nixon Library suffered minor damage as the result of Tuesday’s earthquake, which was centered a few miles from Yorba Linda in the community of Chino Hills. No one was injured. The worst damage was in the White House East Room, where Martha Washington’s portrait and a few chandelier baubles fell to the floor. No structural damage was in evidence on the grounds or in the museum. As the situation was being assessed, Federal officials ordered the Library closed and sent their own and private Foundation staffs home.
