 | Tacoma Narrows Bridge Collapse "Gallopin' Gertie" Watch the amazing "Gallopin' Gertie" November 7, 1940 video clip. 1940 Tacoma Narrows Bridge Slender, elegant and graceful, the Tacoma Narrows Bridge stretched like a steel ribbon across Puget Sound in 1940. The third longest suspension span in the world opened on July 1st. Only four months later, the great span's short life ended in disaster. "Galloping Gertie," collapsed in a windstorm on November 7,1940. The bridge became famous as "the most dramatic failure in bridge engineering history." Now, it's also "one of the world's largest man-made reefs." The sunken remains of Galloping Gertie were placed on the National Register of Historic Places in 1992 to protect her from salvagers. A dramatic tale of failure and success The story of the failure of the 1940 Narrows Bridge and the success of the Current Narrows Bridge is a great American saga. When Galloping Gertie splashed into Puget Sound, it created ripple effects across the nation and around the world. The event changed forever how engineers design suspension bridges. Gertie's failure led to the safer suspension spans we use today. |

 | SR 520 Floating Bridge - Simulated failure by wind storm This simulation highlights what might happen in the event of a complete and catastrophic failure of the SR 520 Floating Bridge. This catastrophic failure would most likely occur during a 20-year wind storm; or a storm with sustained winds exceeding 75 mph. |

 | San Francisco Earthquake and Fire April 18, 1906 The California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time. Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size. Rupturing the northernmost 296 miles (477 kilometers) of the San Andreas fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length. Indeed, the significance of the fault and recognition of its large cumulative offset would not be fully appreciated until the advent of plate tectonics more than half a century later. Analysis of the 1906 displacements and strain in the surrounding crust led Reid (1910) to formulate his elastic-rebound theory of the earthquake source, which remains today the principal model of the earthquake cycle. This footage is some of the earliest known from a natural disaster.
