1994年的北岭地震和1971年的圣费尔南多地震使加利福尼亚州圣费尔南多谷范诺曼建筑群的上、下圣费尔南多大坝受到强烈的近源地面运动的影响。1994年，这些土坝停止使用，只保留了几米的水，由于其水力填充物的液化而广泛破裂和沉降。随着上游斜坡下的水力填充物液化，圣费尔南多大坝下游向上游移动了15厘米。上圣费尔南多大坝移动得更厉害，形成了复杂的三维形状。1994年北岭地震期间，上、下圣费尔南多大坝的反应虽然没有1971年那么显著，但却为岩土工程学界提供了两个有用的历史案例。
The 1994 Northridge and 1971 San Fernando Earthquakes subjected the Lower and Upper San Fernando Dams of the Van Norman Complex in the San Fernando Valley, Calif., to strong near-source ground motions. In 1994, these earth dams, which were out of service and retained only a few meters of water, extensively cracked and settled due to the liquefaction of their hydraulic fill. The Lower San Fernando Dam moved over 15 cm upstream as the hydraulic fill liquefied beneath its upstream slope. The Upper San Fernando Dam moved even more and deformed in a complicated three-dimensional pattern. The responses of the Lower and Upper San Fernando Dams during the 1994 Northridge Earthquake, although less significant than in 1971, provide the geotechnical engineering community with two useful case histories.
