How An Earthquake Moved A Civilization
Sanxingdui was a Bronze Age civilization which flourished in China’s fertile Sichuan River basin. That’s a ways away from the Yellow River, cradle of Chinese civilization – or so archaeologists had thought before Sanxingdui was uncovered. It was strong for several hundred years, but around 1100 or 1200 BCE mysteriously vanished. Around that same time, a similar civilization appeared in Jinsha, about thirty miles from Sanxingdui. Archaeologists and historians generally accept that Sanxingdui became Jinsha, its culture continuing simply in a different place. Now, a new theory suggests why.
The first clue is that ravines and beds of waterways to and passing the Sanxingdui site are wider than their current amounts of water suggest should be. They were likely filled with much more water, once. This lead to Sichuan University scientist Niannian Fan’s hypothesis that perhaps an earthquake in the mountains feeding the streams and rivers, similar to the 2008 Sichuan earthquake, sharply decreased the water level in Sanxingdui. Using google earth, Fan found a stretch of mountainous terrain through which the old river would have flowed lacks signs of glacial erosion which should have been there. This mountain section’s erosion signs may have been covered up by a long-ago landslide. Finally, ancient records from the capital of the Zhou Dynasty record an earthquake which occurred in 1099 BCE. Although 300 miles from what Fan presumes is the earthquake’s epicenter near Sichuan, its magnitude would have ensured the earthquake was felt even in the Zhou capital.
This does not answer every question about Sanxingdui. Why did they move to Jinsha, specifically? How was this accomplished – over a generation, or within a harvest season or two of the earthquake? What impact did the earthquake and its aftermath have on the culture? These are questions for archaeologists to answer, as they find more evidence about both civilizations.

Consumers don’t need to use antibacterial soaps, and some of them may even be dangerous, the Food and Drug Administration says.
On Friday, the FDA issued a rule banning the use of triclosan, triclocarban and 17 other chemicals in hand and body washes. which are marketed as being more effective than simple soap.Companies have a year to take these ingredients out of their products or remove the products from the market, the agency said.
“If the product makes antibacterial claims, chances are pretty good that it contains one of these ingredients,” Theresa Michele, director of the FDA’s Division of Nonprescription Drug Products, said Friday in a conference call with reporters.
The ban applies only to consumer products, not to antibacterial soaps used in hospitals and food service settings.
