Oddly enough it was earlier last week I was thinking about writing this long before the earthquake hit Japan. It’s one of those funny, duh kinds of things that just has me scratching my head sometimes. Notice the sign to the left. Good idea to know which direction to go in case of a Tsunami emergency.
I’d like to talk a little bit about tsunamis and San Francisco. We used to get tidal wave alerts fairly often out in the Sunset with warning to expect flooding. You know what we used to do? Drive down to the beach to watch and see if the big wave ever came. Absolute opposite to what a person should do, but we did it anyway. Guess what. No tsunami’s ever came. Even if we did get a big one there’s a few hurdles it would have to cross first.
- There’s either concrete walls or rock and sand piled up at the beach that reaches close to 30 feet. The waves that devastated Crescent City in 1964 topped 20′. We’d need something a lot bigger than that.
- The 8.9 or 9.1 quake that hit Japan has no chance of happening here according to experts because of the way the San Andreas Fault is built, plus our fault line is inland, not 10=15 miles off shore.
- If a wave did manage to pass over the rock, sand and concrete it would have to drop about 40′ into a trough like area that runs uphill for about 4 blocks before you’re at the same level as the top of the sand.
So all in all we’re pretty safe. My house is over 100 ft above sea level so I know I’m safe and if there’s ever a chance I’m not then there’s pretty much no where in San Francisco you’d be safe.
Now back to the picture. That picture was taken at the foot of Judah street right across the street from Java Beach cafe. If you turn 180° this is what you see. OCEAN BEACH! Ok, I kind of took a few liberties with the picture, but basically the sign is right across the street from the beach.
Yes, this sign was money well spent for people who ride on a short bus to their meetings at the low IQ club. No where else further up Judah is there another sign except over on Lincoln Blvd where there’s one a block up from the beach. No other street has signs like this so I suppose the city of San Francisco is telling residents that if you live in the northern part of the Sunset District you probably aren’t very smart.
