The Earthquake That Changed California Building Laws: Long Beach Disaster Photo Archive of 28 Photogrphs, 1933

1933. The aftermath of destruction left by the March 10, 1933 Long Beach earthquake photo archive of 28 images. This earthquake had a magnitude 6.4 shock on the Newport-Inglewood Fault that struck at 5:54 p.m. and killed roughly 120 people. The earthquake struck during the depths of the Great Depression, when many Long Beach residents and businesses were already financially strained, leaving thousands temporarily homeless and forcing schools, stores, theaters, and municipal buildings to close or be demolished at enormous cost. In the months that followed, federal relief funds, emergency labor, and sweeping new California seismic building laws transformed reconstruction into one of the earliest large-scale earthquake safety campaigns in the United States.

Photo archive of 28 black and white RPCCs, each measuring 3.5" x 5.5". The scenes move through Long Beach's damaged civic, school, commercial, and entertainment districts. Captions in the negative identify the following; Poly High School, Jefferson High School, the Home Theatre, the Pike amusement district, East Anaheim Avenue, Third and Pine, a post office, apartment houses, lunch rooms, storefronts, hotels, laundries, and street corners buried under brick, plaster, cornices, signs, and collapsed walls. Some photos show civilians observing, guarding, or cleaning up destroyed sites.
The earthquake exposed the danger of unreinforced masonry buildings across Southern California; school damage was so severe that California passed the Field Act the same year, requiring stronger public-school construction standards. These postcards preserve the immediate street-level aftermath with pedestrians standing before wrecked facades, open interiors where upper stories have fallen away, business signs hanging over rubble, and Long Beach's built environment caught at the moment it forced California to rethink earthquake safety.
