Santa Clarita is near the San Fernando fault zone and was affected by the 1971 San Fernando earthquake, also known as the Sylmar quake. The city was also affected by the 1994 Northridge earthquake, and many commercial and residential buildings were devastated by its aftermath, including the nearby Newhall Pass, the Valencia Town Center, and Six Flags Magic Mountain. Magic Mountain's 38-story Sky Tower swayed six feet in each direction during the Northridge earthquake with only minor damage.
