Image From Space Shows Downtown San Francisco Sinking Slowly Around Millennium Tower

A few-inches dimple way downtown is not a problem. Most of the city sits on rock way above sea level and isn't going anywhere. The MT building was badly designed and ugly besides.

New Orleans, Houston, Miami, Jakarta are really sinking.

Here's one example of rock way above sea level

and in an earthquake, the 'isn't going anywhere' label doesn't apply.

Rock does have an advantage over soil, in that it doesn' liquefy. It can still move dangerously, and the geologic history we know indicates a lot of it has done so.

I don't know of any big rocks like that in SF. There is some smaller stuff in Glen Canyon that, low-probability, could take out some hikers.

We do have a lot of eucalyptus trees. They are non-native and shallow rooted, so occasionally fall over even without an earthquake.

The MT building is leaning *over 0.1 degrees* now. I calculate that if you and Fred stay at least 2500 miles away, you might survive the crash.

It's a bloody big problem if one side of the tower is on rock (or just on firmer soft stuff) and the other isn't, though.

MT is super heavy and none of the pilings reach bedrock.

The real problem is that the building is full of lawyers.

That's a problem? The only problem I see here is if they get enough warning of its sudden collapse.

0.11 degres of tilt in 12 years. Sea level rise will submerge it before it collapses.

Millennium Tower is leaning North-East.

Mo wanted to walk the Salesforce elevated garden so I grumbled and went with her, a short BART ride from our village.

The adjacent building is the Millennium Tower. You can't compare it against Salesforce because Salesforce is curved, but if you line up an edge against nearby square buildings there is no visible lean. 0.11 degrees would be hard to see and I doubt that the other buildings are vertical to 0.11 degrees either.

At least she bought me a beer.

Better find something else to get worked up about. Albatross divorce rates maybe.
