Summary of the article:
Is the tallest building in San Francisco sinking? San Francisco’s Millennium Tower has been sinking and leaning for years and the final phase of the fix is now underway.
Key Points:
1. The Millennium Tower can withstand at least 70 inches of tilt to the west and 30 inches to the north before its ability to resist earthquakes would be compromised.
2. San Francisco Bay is a large, nearly landlocked bay connected with the Pacific Ocean by the Golden Gate strait.
3. A new report suggests that sinking land, known as land subsidence, will increase the potential reach and damage of flooding in the Bay Area by the year 2100.
4. Some parts of San Francisco’s Mission Bay neighborhood are sinking due to the dirt and rock fill from the 1800s.
5. The tallest structure to collapse was the Warsaw Radio Mast in Poland, standing at 2120 ft, until its collapse in 1991.
6. The Leaning Tower of Pisa won’t fall due to dynamic soil-structure interaction between the soil’s softness and the tower’s height and rigidity.
7. The Leaning Tower of Pisa was saved from falling by a method called soil extraction, where tunnels were dug to remove earth and steel cables helped pull it back into position.
Questions and Answers:
- Q: How far can the Millennium Tower lean before falling?
A: According to analyses, the building can withstand at least 70 inches of tilt to the west and 30 inches to the north before its ability to resist earthquakes would be compromised. - Q: Is San Francisco near a body of water?
A: Yes, San Francisco is near San Francisco Bay, which is connected to the Pacific Ocean by the Golden Gate strait. - Q: Could more of the Bay Area be underwater in 2100 than previously expected?
A: Yes, a new report suggests that sinking land will increase flooding potential in the Bay Area, submerging a larger portion of the region by 2100 than previously estimated. - Q: Is Mission Bay in San Francisco sinking?
A: Yes, some parts of San Francisco’s Mission Bay neighborhood are sinking due to the fill from the 1800s. - Q: What was the tallest structure to collapse?
A: The Warsaw Radio Mast in Poland was the world’s tallest structure until its collapse in 1991. - Q: Will the Leaning Tower eventually fall?
A: No, the Leaning Tower of Pisa won’t fall due to dynamic soil-structure interaction. - Q: What keeps the Leaning Tower from falling?
A: The method called soil extraction was used to save the Leaning Tower of Pisa. Engineers dug tunnels on the north side and removed earth, while steel cables helped pull it back into position.
Is the tallest building in San Francisco sinking
San Francisco's Millennium Tower has been sinking and leaning for years and the final phase of the fix is now underway.
How far can the Millennium Tower lean before falling
“I have performed analyses that indicate the building can withstand at least 70 inches of tilt to the west and 30 inches to the north before its ability to resist earthquakes would be compromised.
Is San Francisco near a body of water
San Francisco Bay, large, nearly landlocked bay indenting western California, U.S. It is a drowned river valley paralleling the coastline and is connected with the Pacific Ocean by a strait called the Golden Gate, which is spanned by the Golden Gate Bridge.
Could more of the Bay Area be underwater in 2100 than previously expected
A new report suggests that sinking land, known as land subsidence, will increase the potential reach and damage of flooding in the Bay Area, submerging a larger portion of the region by the year 2100 than previously estimated.
Is Mission Bay in San Francisco sinking
Before Chase Center and multi-million dollar constructions were going up, San Francisco's Mission Bay neighborhood was filled with dirt and rock in the 1800s and now some parts of it are sinking.
What was the tallest structure to collapse
The Warsaw Radio Mast (Polish: Maszt radiowy w Konstantynowie) was a radio mast located near Gąbin, Poland, and the world's tallest structure at 2120 ft (646.38 m) from 1974 until its collapse on 8 August 1991.
Will the Leaning Tower eventually fall
The Leaning Tower of Pisa won't fall due to something called dynamic soil-structure interaction, which describes the relationship between the soil's softness and the tower's height and rigidity.
What keeps the Leaning Tower from falling
The method – known as soil extraction – saw engineers dig a series of tunnels on the north side of the tower and remove small amounts of earth. (The tower leans to the south.) Steel cables helped pull it back into its original position.
Can you ever swim in San Francisco

The method – known as soil extraction – saw engineers dig a series of tunnels on the north side of the tower and remove small amounts of earth. (The tower leans to the south.) Steel cables helped pull it back into its original position.
How deep is the deepest part of the SF bay
372 ft
The deepest part of the bay is under and out of the Golden Gate Bridge, at 372 ft (113 m). In the late 1990s, a 12-year harbor-deepening project for the Port of Oakland began; it was largely completed by September 2009.

The average depth of the bay is about 12-15 feet deep. Heck, between Hayward and San Mateo to San Jose it averages 12 to 36 inches. So much for that bridge! With that said though, the water surrounding Alcatraz is on the deeper end of the scale, but still, it's just an average depth of 43 feet.
Has anyone swam from Alcatraz to shore
