"The Northern California earthquake of April 18, 1906, commonly referred to as the “Great San Francisco Earthquake of 1906", is the most damaging earthquake in US history. San Francisco and surrounding cities were violently shaken by seismic waves produced by the magnitude 7.8 earthquake. The remarkable post-earthquake construction and renaissance of the Bay Area are important events in the history of the region. The 1906 earthquake also revealed the existence and significance of the San Andreas fault to earth scientists, who then gave birth to the science of earthquakes. This virtual tour utilizes the geographic interactive software Google Earth to explain the scientific, engineering, and human dimensions of this earthquake, so as to help you visualize and understand the causes and effects of this and future earthquakes."
