Earthquake in China Caused by Dam After All?

In September I questioned the theory going around that the devastating  Sichuan province earthquake in May was caused by the Three Gorges Dam. The idea was inspired by research out of the Geophysical Institute at the University of Alaska in 1999 (long before Three Gorges was built) that said that the weight of the water held back by the dam could cause “reservoir-induced seismicity.” The problem with Probe International’s charge was that the fact that Three Gorges happens to be 400 miles from the epicenter. But now scientists have found that a closer dam might have contributed to tectonic shifts of the 7.9 variety, that its several hundred million tons of water would have put “25 times” the stress of natural tectonic movements on the fault line.

That the dam involved is not the controversial Three Gorges doesn’t lessen the consequence here: an earthquake caused by a man-made dam means the government has to answer, at least in part, for 80,000 deaths.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
