San Francisco sirens sound at 5:12 am for 100th anniversary. Options

[Paul Cowan]

Residents of the bay area were awakened by sirens wailing across the city as the 5:12 am moment marked the 100th anniverary of the famous 7.8 earthquake.

There were memorials held at several cities along the San Andreas fault that suffered casualties in the quake. Some cities had candlelight marches to cemetaries where quake casualties are buried.

As seems to be the practice when disaster strikes a major area, the death toll for the 28 second quake in San Francisco was greatly under estimated. A final figure is still not known but by latest estimate done on Monday it is thought to be over 3,000 and could be as high as 6,000.

If the future quake that WILL hit San Francisco is as strong as 7.8..it is estimated it will kill between 1,800 to 3,400 people, damage 90,000 buildings, displace 250,000 households and do $150 billion in damage and that is just in San Francisco.
