Well before my time, but the wik says:

The 1952 Kern County earthquake occurred on July 21 in the southern San Joaquin Valley and measured 7.3 on the moment magnitude scale.
The main shock occurred at 4:52 am Pacific Daylight Time (11:52 UTC), killed 12 people and injured hundreds, and caused an estimated $60 million in property damage.
A small sector of damage near Bealville corresponded to a maximum Mercalli intensity of XI (Extreme), though this intensity rating was not representative of the majority of damage.
The earthquake occurred on the White Wolf Fault near the community of Wheeler Ridge and was the strongest to occur in California since the 1906 San Francisco earthquake.
The town of Tehachapi suffered the greatest damage and loss of life from the earthquake, though other locations in Kern County experienced significant damage as well, but its effects were widely felt throughout central and southern California.
The July mainshock had a significant aftershock sequence that persisted into July and August with many magnitude 5+ events with intensities of V (Moderate) to VII (Very strong).
Six of these aftershocks occurred on the day of the mainshock, but the strongest aftershock came on August 22 as a M5.8 event that had a maximum perceived intensity of VIII (Severe) and resulted in the deaths of two people and caused an additional $10 million in property damage.
