Comment on "Outburst flood at 1920 BCE supports historicity of China's Great Flood and the Xia dynasty".

Wu et al (Reports, 5 August 2016, p. 579) reported geological and archaeological evidence about an earthquake-induced landslide dam outburst flood around 1920 BCE and claimed a support to the historicity of China's legendary Great Flood and Xia dynasty. We argue that the physical evidence is unreliable and their arguments are unconvincing.
