Bay Area Liquefaction, Landslide, and Seismic Zones – Mapped

Lots of talk in the news these days about landfill, liquefaction, and general stability of property in and around San Francisco’s waterfront, and entire city for that matter (see “SF’s landmark tower for rich and famous is sinking and tilting“that hit newsstands and internets today [SF Gate/Chronicle]).

Big news, no doubt, but what about the rest of us?

I did a post waaaay back in 2010, preceded by the post I did even further back in 2008, both of which get hundreds, sometimes thousands of views daily, so I know for sure this is a topic of interest when buying/selling property in San Francisco. And since I get so many questions about whether the property you want to buy is, or is not, in liquefaction, let me be clear, I AM NOT A SEISMOLOGIST, GEOLOGIST, SCIENTIST, OR ANY TYPE OF OTHER EXPERT IN THE FIELD OF EARTHQUAKES, LIQUEFACTION, LANDSLIDES, LANDFILL, MUD FILL, BEDROCK, SETTLING, SLOPING, SLIPPING, SLIDING, OR ANY OTHER FIELD OF INTEREST THAT HAS LED YOU TO THIS SITE FOR KNOWLEDGE ABOUT LIQUEFACTION. I AM A REALTOR, AND EXPERT AT MARKETING PROPERTY FOR SALE, AND HELPING BUYERS BUY. WHAT I AM SHARING HERE IS MEANT TO BE A RESOURCE FOR YOU TO MAKE YOUR OWN EDUCATED DECISIONS. DO NOT RELY ON THE INFORMATION POSTED HERE FOR YOUR PROPERTY PURCHASE OR SALE.

That said, I want to share a new App/site with you: Temblor…all things Seismic. You have to check it out. It’s awesome, and will hook you in for hours.

Check out this screenshot of the entire Bay Area…including liquefaction zones, fault lines, and recent quakes.

Now zoom in to San Francisco…

As I sit in my home office, which, according to Temblor, is built in an area of “moderate Liquefaction Susceptibility”, and a “Seismic Hazard rank of HIGH” (I challenge you to move the pin and find an area in SF that is not “High”), it’s left me wondering…does this change anything for me, and my decision to own property where I do? No. It doesn’t. It’s better than a map telling me I live in an area of High Tornado Susceptibility, where I roll the dice on a pair of glass slippers showing up on my doorstep.

So, there you go. Plug in your address, your mom’s address, your brother’s address, your employer’s address and see how you all stack up. This is yet another amazing resource, thanks to the Internet, available to everyone and anyone with even a remote interest in Earthquake activity (I’m guessing that’s everyone in California, at least). And I’m pleased to be sharing it with you.

Full disclosure, yes, I chatted with the founders of this service, no, they are not paying me for this post. I have downloaded the app, and refer to it constantly.

Happy Monday.

Crime, Toxic Sites, Plan Your San Francisco Halloween (Or Home Search) With These Fun Maps!

It’s no secret, we love Property Shark, and if you’re serious about your San Francisco house hunting or Halloween, you should too. They’ve just released a new Crime Map that is frighteningly detailed (click on maps for larger images):

A little zoom goes a long way when you’re looking to score (Trick-or-treating in this area, the Tenderloin, not advised. Unless, of course, you like rock candy):

Ahhh….it gets better. Pair that crime map with their Toxic Sites Map and you have the recipe for hours of jaw-dropping fun! (It’s not advised to accept apples or organic “treats” from homes with a red “+” when trick-or-treating.)

For all of you home seekers, consider yourself disclosed as to whether those drug dealers out front of your dream home are there often, and whether that funny looking steel pipe coming up from the sidewalk really carries any significance or not. ;-)

Thank you to PropertyShark, and an early Happy Halloween to you all.
