11.4 The following shows ground motion recordings from two adjoining islands in the San Francisco Bay during the 1979 Loma Prieta earthquake. Treasure Island and Yerba Buena Island are both located at a distance of about 50 miles from the epicenter. Treasure Island was created in the 1930s by filling sand over underwater bay mud deposits, while Yerba Buena Island is a natural rock outcrop. The recordings showed a significant difference in amplification between the two adjacent sites. 6.
