It was 5:13 a.m. 105 years ago when the earthquake stuck San Francisco.
The shaking lasted for 40 seconds, but the damage, and memories, extended much past that time.

The 8.3 temblor is now known as the 1906 earthquake, and it is still one of the worst disasters to hit San Francisco.
Pacifica was the actual epicenter of the earthquake that killed 3,000 people and injured another 25,000, causing $400 million in damage.
