Empress Theatre (California) repainted and the "Empress Theatre" sign was painted into the pediment. Its window panels were uncovered and refurbished, seats from Fox Theatres were salvaged and installed, gypsum decoration was re-gilded, and period-appropriate carpeting was laid. The Empress thrived throughout the decade. 1989 On Tuesday October 17, the Loma Prieta earthquake, measuring 6.9 on the moment magnitude scale, shook the San Francisco Bay Area; the Empress Theatre was not spared. To repair damage from the quake and make the building seismically safe for use was a task so monumental that it caused the theatre to sit vacant and derelict for nearly
1989 Loma Prieta earthquake by the WGCEP in 1988 was coincidental. The contrasting characteristics of the 1906 and 1989 events were examined by seismologists Hiroo Kanamori and Kenji Satake. The significant amount of vertical displacement in 1989 was a key aspect to consider because a long-term sequence of 1989-type events (with an 80–100-year recurrence interval) normally result in regions with high topographic relief, which is not seen in the Santa Cruz Mountains. Three scenarios were presented that might explain this disparity. The first is that the geometry of the San Andreas Fault goes through a transition every several thousand years. Secondly, slip type could
