SAN FRANCISCO EARTHQUAKES OF 1989 AND
1906
It can take seconds to destroy almost everything and turn two
beautiful days into two memorable tragedies. Those days were the
1906 and 1989 earthquakes that shook everyone into shock around
the world, but especially in San Francisco.
INTRODUCTION
I noticed that I had more information on the 1989 earthquake than the 1906 because of
technology and growth.
NOTICE!
October 18, 1989, an earthquake struck right after
5:00 P.M in San Francisco.
The earthquake lasted about 15 seconds and was caused by a slip along the San Andreas
Fault.
1989
The epicenter or center of the earthquake was in the forest of
Nisene Marks State park.
1989
It was the strongest earthquake to hit since 1906, with a magnitude of 7.1.
1989
The earthquake was broadcast on live television.
It is referred to as the “ World Series Quake” because it occurred during the World Series.The third game of the series was postponed for
10 days!
1989
A quote from Cole Emerson,“ Floors and walls began to shake violently, desk
was moving so rapidly, hard to stay under it, windows falling.”
1989
Most damage was in San Francisco, Oakland, and Santa
Cruz.
Not as badly damaged areas were Hayward, San Mateo,
Monterey, and Boulder Creek.
1989
Oakland Bay Bridge was damaged when the span of the top deck collapsed.
They stated on Tuesday the Bay Bridge would be fixed by Thursday, but on Friday they stated it
would be fixed within one to two months! I can’t believe how many people would cross
that bridge to get to so many places, but now they had to wait for weeks!
1989
The San Francisco Airport was closed because of cracks in the runway and there were large amounts of fires from
gas explosions.
1989
The property damage for the earthquake was over $5.9 billion!
1989
2,575 buisnesses were damaged!
The areas hardest hit were Watsonville, Los Gatos, San
Francisco, Oakland, and Santa Cruz.
1989
Lost main business section due to collapsed buildings.
WATSONVILLE
Eight blocks of buildings with major structural damage.
LOS GATOS
Power outages, broken windows, and lots of structural damage as
well.
SAN FRANCISCO
Had 10 blocks of building damage.
OAKLAND
Had 12 blocks of major building damage..
SANTA CRUZ
Out of those 5 cities 50% of the buildings would be demolished.
1989
18,300 damaged homes and estimated 12,000 people homeless.
More than 60 deaths and 3,757 people estimated injured.
Cypress Street Viaduct caused most of the deaths.
1989
SAN FRANCISCO EARTHQUAKE OF 1906
April 18, 1906 at 5:13 A.M an earthquake hit San Francisco for 1 minute with a magnitude of 7.9.
It could be felt from Oregon to Los Angeles and inland to
Nevada.
1906
It ruptured the San Andreas Fault to the North and South of the city with a total of 296 miles out of 800 – mile San Andreas
Fault.The San Andreas Fault is between the
Pacific plate and the North American plate.
1906
The ground west of the fault moved northward.
A 21 foot shift was measured.
1906
The earthquake destroyed the cities water mains which resulted to the firefighters not being able
to put the fires out.
Fires burned for several days.
1906
The quake took second place to the great fire that followed, lasting 4 days. Most
likely caused by broken gas lines.Since the fire started it destroyed the
central business district.
1906
The population was 400,000 people.
More than 3,000 people died and 250,000 San Francisco
residents homeless.
1906
Damaged towns were San Francisco, San Jose, Salinas, and
Santa Rosa.
28,000 buildings wee destroyed and 500 city blocks were
destroyed.
1906
Damages were estimated around $500,000,000 in 1906 dollars which would translate to about 8.5 billion
dollars today. When I read that sentence when I was
researching all I could think was “ Wow! That’s a lot of money!”
They quickly recovered and destruction allowed planners to create a new, improved
city.
1906
Think about what your plan would have been if you
experienced one of those days. Enjoy every second of life because it takes only a few seconds to turn
a good day into a bad one.
