The quake’s epicenter, located in Los Angeles’ San Fernando Valley, delivered a potent shockwave that caused catastrophic damage and claimed dozens of lives.
The shaking lasted 10-20 seconds. Freeway overpasses and bridges crumbled, while buildings, particularly those in the San Fernando Valley, suffered extensive structural damage.
Human casualties were substantial with 57 lives lost and over 8,700 reported injuries. The collapse of buildings and bridges contributed significantly to the human toll.
Damage estimates ranged from $13 billion to $50 billion, and the economic toll extended even further.
The emergency response was swift with coordinated efforts from local, state, and federal agencies conducting search and rescue operations. The recovery phase focused on rebuilding damaged infrastructure and implementing stringent building codes to bolster seismic resilience.
