The capacity of the Matadome has changed throughout the years . Before the 1994 Northridge earthquake , the Matadome had a capacity of over 3,000 . The record attendance was 3,106 for a United States men 's national volleyball team exhibition against Japan men 's national volleyball team set on 2 November 1990 , which was prior to the earthquake . After the earthquake , the upper section seats were removed to create more classroom space for Redwood Hall , and walls were put up to separate the Matadome from these new classrooms
