The Hayward fault bisects Memorial Stadium along its length. Memorial Stadium was built in two halves in 1923 in the apparent hope that they would just ride out a major earthquake. The expansion joint to the right of the middle arch shows some of the shifting that has occurred due to fault creep. Rebuilding of the stadium is to be finished in 2013.
Latimer Hall was built in the early 60's with then-state-of-the-art earthquake engineering. The box columns were designed to resist lateral forces. However better technology in the late 90's gave the building a poor earthquake rating. The balconies with a different concrete color were added then.
Hildebrand Hall, built in the mid-60's, received a poor earthquake rating in a late 90's analysis. The diagonal braces are unbonded braces, part of a light, cheap and aesthetic fix, made of both metal and concrete to be strong both in tension and compression.

South Hall, the oldest building on campus, was designed in 1870 to be earthquake-resistant. In the 1980's, the walls were tied together with reinforcing rods; the interior was gutted and bricks tied to walls of reinforced shotcrete; on the exterior, the chimneys were replaced with plastic replicas.
The Hearst Mining Building was designed by John Galen Howard and completed in 1907. The building received a "very poor" earthquake rating in the late '90s. To save the beautiful building, the expensive solution of base isolation was used - it rests on 134 steel-rubber columns that can move 28 inches in any horizontal direction.
