Periodic earthquakes affect the Olympia area. The 1949 earthquake damaged many historic downtown buildings beyond repair, and they were demolished. Others were retrofit with new facades to replace the damaged Nineteenth century wood and glass storefronts. Subsequently, much of Olympia's downtown reflects mid-twentieth-century architectural trends. Olympia also suffered significant damage from the 1965 Puget Sound and 2001 Nisqually earthquakes. It was the closest major city to the epicenter of the 2001 event.
