Multiple Chinese media recently reported that the water of a waterfall in the Old Dragon Cave at the Rengu Scenic Site in Sichuan, China, turned red the afternoon of March 11, just after the 9.0-magnitude earthquake in Japan.
Every time an earthquake occurred in Asia, the water from the waterfall turned red, China Broadcast Network reported. Local residents told China Broadcast Network that the same phenomenon occurred during the 1976 Tangshan earthquake, the 1999 Taiwan earthquake, and the 2008 Sichuan earthquake.
According to Chinese media, geologists think that the change in the water’s color is caused by minerals.
Although Chinese media describe the color as being blood-red, especially during the 2008 Sichuan earthquake, photos published in 2008 in Dazhou News, a local media outlet, show that the color is more brownish-orange, similar to that of rusted iron.
