The Three Gorges Dam is only built to withstand an earthquake of 7.0, Nepal was 7.8

Environmental Risks of the Three Gorges Dam - HowStuffWorks

13 cities, 140 towns and 1,350 villages and more than 1,300 historical sites all ended up underwater.

An increase of 3,000 earthquakes a year since completion.

Engineers from the US and Great Britain refused to work on it calling it a disaster in the making.

It changed the rotation of the planet.

Damming The Three Gorges - Chapter Ten - Dam Safety Analysis

• Failure to consider downstream effects of cofferdam failure
  
  During the construction of the project a series of temporary cofferdams would be constructed across the river in order to divert its flow. The second and third phase cofferdams would, at best, be capable of withstanding a 100-year flood and a 200-year flood, respectively. If larger floods occur, these cofferdams could quickly wash out,* releasing a flood wave that would overwhelm the Gezhouba Dam** and continue downstream to overtop the Jingjiang Dyke, drowning hundreds of thousands of people. CYJV estimates the probability of such a catastrophe to be about 1 in 20, which should be considered an unacceptably high risk.

Wow, 1 in 20



Areas that will be devastated when the dam breaks:

The Earth will take back what's hers eventually.

 

[Stephanie]

the sky is falling. some people just needs a reason to live in miserable fear all the time

what the earthquake doesn't kill in People, that dam break will

should make the progressives in this Obama administration happy, they believe we are overpopulated already. didn't need the gas ovens afterall

 

[Billy_Bob]

The potential dam failure is nothing compared to killing millions with the global warming scam.. I guess you pick prosperity and the price that comes with it or you try and stop prosperity and kill millions.

The left is stuck on stupid.. chicken little syndrome...

 

[pismoe]

an under engineered Dam in China you say , well better that its in China rather than the USA !!

So the building of this dam changed the rotation of the planet?? ...... ....

I heard the same Sunni , course I don't know .

 

[Old Rocks]

It is not only China that has a problem with dams underbuilt considering what we now know concerning seismic hazards.

How Infamous Hydroelectric Dam Changed Earth s Rotation - From Quarks to Quasars

Three Gorges Dam crosses the Yangtze River in Hubei province, China. It is the world’s largest hydroelectric power station by total capacity, which will be 22,500 MW when completed. When the water level is at maximum….it will flood a total area of 632 km2 of land. The reservoir will contain about 39.3 cubic km (9.43 cubic miles) of water. That water will weigh more than 39 trillion kilograms (42 billion tons).

A shift in a mass of that size will impact the rotation of the Earth due to a phenomena known as “the moment of inertia”, which is the inertia of a rigid rotating body with respect to its rotation. The moment of inertia of an object about a given axis describes how difficult it is to change its angular motion about that axis. The longer the distance of a mass to its axis of rotation, the slower it will spin. You may not know it, but you see examples of this in everyday life. For example, a figure skater attempting to spin faster will draw her arms tight to her body, and thereby reduce her moment of inertia. Similarly, a diver attempting to somersault faster will bring his body into a tucked position.

Raising 39 trillion kilograms of water 175 meters above sea level will increase the Earth’s moment of inertia, and thus slow its rotation. However, the impact will be extremely small. NASA scientists calculated the shift of such a mass will increase the length of day by only 0.06 microseconds, and make the Earth only very slightly more round in the middle and more flat on the top. It will also shift the pole position by about two centimeters (0.8 inch). Note that a shift in any object’s mass on the Earth relative to its axis of rotation will change its moment of inertia, although most shifts are too small to be measured (but they can be calculated).”

Not to worry, though. Earth’s rotation changes frequently, with many different variables added into the equation. First, we have the moon gradually receding from the Earth changing Earth’s rotation ever-so-slightly. Earthquakes (like the mega quake in Japan back in 2011) also help along the process (the same quake changed Earth’s rotation by 2.68 microseconds). Furthermore, every 5 years (or so), the length of the day increases and decreases by about a millisecond, or about 550 times larger than the change caused by the Japanese earthquake.

We experiance minor changes in the Earth's rotation all the time. No biggie.

I'm curious. Why do you call yourself an engineer? You even have Google to help you.

It can't be as bad as the Soviets trying to reverse the flow of a river..

It is actually weakening the Earth's magnetic field of flux...

So I supplied a Google search with thousands of links giving examples of how it happens and how it's done. Without a shred of evidence, you are saying "I WON'T believe it". That's why it's difficult to believe anyone with such a lack of curiosity and a closed mind could ever be an engineer.

The articles said the theory of this dam affecting the earth's rotation was based on a mathematical calculation. And has never been measured or proven with scientific instruments.

In my profession we only deal with reality. Tangible things which can be measured, quantified, tested, and verified.

Which explains why I'm a Republican and you are a Democrat. .....

As the saying goes, three Gorges are better than one.

The earthquake that caused Japan's tsunami caused a detectable change in Earth's rotation if I remember correctly. All earthquakes do, but only big ones can be actually measured.
