Damage slight in specially designed structures considerable damage in ordinary substantial buildings with partial collapse. Damage negligible in buildings of good design and construction slight to moderate in well-built ordinary structures considerable damage in poorly built or badly designed structures some chimneys broken. Some heavy furniture moved a few instances of fallen plaster. Sensation like heavy truck striking building. Dishes, windows, doors disturbed walls make cracking sound. Felt indoors by many, outdoors by few during the day. Vibrations similar to the passing of a truck. Many people do not recognize it as an earthquake. Felt quite noticeably by persons indoors, especially on upper floors of buildings. Felt only by a few persons at rest, especially on upper floors of buildings. Not felt except by very few under especially favorable conditions.

(from: United States Geological Survey Professional Paper 1527: Seismicity of the United States, 1568-1989, (revised), by C.W. The California Institute of Technology at Pasadena recorded 188 aftershocks of magnitude 4.0 and higher through Septemsix aftershocks on July 21 were of magnitude 5.0 and higher. It was observed at such distant points as Stirling City, California, Phoenix, Arizona, and Gerlach, Nevada. The main shock was felt over most of California and in parts of western Arizona and western Nevada. At least one building was damaged in San Diego, and in Las Vegas, Nevada, a building under construction required realignment of the structural steel. Water also splashed in pressure tanks on tops of buildings in San Francisco. Water splashed from swimming pools as far distant as the Los Angeles area, where damage to tall buildings was nonstructural but extensive. Reports of long-period wave effects from the earthquake were widespread. Similar kinds of damage also occurred at Arvin, which lies southeast of Bakersfield and west of Tehachapi. Multistory steel and concrete structures sustained minor damage, which commonly was confined to the first story. In contrast, however, the Kern General Hospital was damaged heavily.

Cracks formed in many brick buildings, and older school buildings were damaged somewhat. The generally moderate damage in Bakersfield was confined mainly to isolated parapet failure. Only a few woodframe structures were damaged seriously in this earthquake, compared to the 1933 shock in which many such structures were thrown off foundations. Although damage was severe, the total extent of damage to property did not exceed that in Long Beach in 1933. Property damage was heavy in Tehachapi, where both brick and adobe buildings were hit hard, and 9 people were killed. At Tehachapi, Bakersfield, and Arvin, old and poorly built masonry and adobe buildings were cracked, and some collapsed. Maximum MM intensities in nearby cities did not exceed VIII. Northeast of that highway, the ground was displaced vertically about 60 centimeters and horizontally about 45 centimeters.

Highway 466 (now State Highway 58) settled from a few centimeters to more than 30 centimeters in places, and a large part of the highway was cracked and wrinkled. Fill areas in the mountainous region along U.S. East of Caliente, one large crack, about 1.5 meters at its widest point and more than 60 centimeters deep, was observed. The ground slumped cotton rows were offset more than 30 centimeters and pavement on one highway was crumpled for more than 300 meters. Southwest of Arvin, on the San Joaquin Valley floor, ground cracks traversed and split the concrete foundation of one house, causing partial collapse. The cracking along Bear Mountain indicated that the mountain itself moved upward and to the north. The somewhat flat, poorly consolidated alluvium in the valley was erratically cracked and recontoured. Many surface ruptures were observed along the lower slopes of Bear Mountain, in the White Wolf fault zone. At Owens Lake (about 160 kilometers from the epicenter), salt beds shifted, and brine lines were bent into S-shapes. There, the earthquake cracked reinforced-concrete tunnels having walls 46 cm thick it shortened the distance between portals of two tunnels about 2.5 meters and bent the rails into S-shaped curves. MM intensity XI was assigned to a small area on the Southern Pacific Railroad southeast of Bealville. It claimed 12 lives and caused property damage estimated at $60 million. Kern County Earthquake, 1952: This earthquake was the largest in the conterminous United States since the San Francisco shock of 1906. Kern County Earthquake - 7.3 - July 21, 1952
