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
Earthquake prediction "resoundingly debunked". Probably the most celebrated seismo-electromagnetic event ever, and one of the most frequently cited examples of a possible earthquake precursor, is the 1989 Corralitos anomaly. In the month prior to the 1989 Loma Prieta earthquake measurements of the earth's magnetic field at ultra-low frequencies by a magnetometer in Corralitos, California, just 7 km from the epicenter of the impending earthquake, started showing anomalous increases in amplitude. Just three hours before the quake the measurements soared to about thirty times greater than normal, with amplitudes tapering off after the quake. Such amplitudes had not been seen in two years
