Today’s post is going to be a short add-on to [yesterday’s post](http://brandondonnelly.com/post/173013737738/sinking-tower-solution) about the sinking Millennium Tower in San Francisco. Today, [the New York Times published](https://www.nytimes.com/interactive/2018/04/17/us/san-francisco-earthquake-seismic-gamble.html?utm_source=citylab-daily&silverid=MzEwMTkyMjA5NTEzS0) the below map showing the areas of the city likely to “liquefy in an earthquake.” It goes on to note that “at least 100 buildings taller than 240 feet were built in areas that have a “very high” chance of liquefaction.”

The article might leave you with the feeling that current building codes are inadequate for the pending “Big One” in San Francisco. So I thought I would [reblog this post](http://brandondonnelly.com/post/167383830713/constructing-the-tallest-building-in-san-francisco) from last fall which talks, in more detail, about how one of the best structural engineering firms in the world designed the tallest building in San Francisco.
