On 23 August 2011 a 5.8 magnitude earthquake, centered in Mineral, Virginia, shook the Smithsonian Institution’s Museum Support Center building in Suitland, Maryland. Because of the building’s design and construction, the moderate earthquake caused significant structural damage and flooding. On 27 August 2011, Hurricane Irene brought 10 cm (4 in) of rain into the area, causing the aging and earthquake-damaged roofing system to leak in multiple areas. In less than a week the building constructed in the 1980s as a model for collection preservation had sustained an estimated $11 million in needed structural repairs and seismic upgrades.
