San Francisco Is Sinking Into the Earth, Scientists Say
A US Geological Survey research geophysicist named Tom
Parsons says that San Francisco is sinking into the
Earth.
NBC Bay Area reports that Parsons examined every single
building in the Bay Area, using satellite images
captured by European Space Agency’s Sentinel 1
satellite.
Most of the settling appears to be taking place
downtown, because of the staggering weight and density
of the buildings.
Ominously, at least one is also tilting. According to
The Weather Channel, Millennium Tower earned its
nickname of the “Leaning Tower of San Francisco”
because of how much it’s tilted each year since its
opening in 2009, and NBC says it’s only the third
heaviest building in the city at an estimated 686
million pounds. In 2018, a large new crack had been
found in the building after residents heard a loud
noise.

Experts say many problems may be causing the city to
sink, including the loss of groundwater because of new
construction and that the Millennium’s foundation isn’t
rooted in bedrock.
Concerningly, Parsons told NBC the combined weight of
all the downtown buildings is enough to affect an
earthquake fault, though luckily the famous San Andreas
fault runs offshore before it reaches the city.
And, of course, it all connects to climate change.
“If you have all of this going on when you’re right
near the waterline, in some cases in San Francisco,
then you have to worry about big storms that sea level
comes up and inundation more frequently,” Parsons told
NBC.

Parsons also says he’ll be studying Manhattan next,
according to NBC, to further study the effects of
sinking on coastal cities in light of rising sea
levels.
