The International Atomic Energy Agency (IAEA) had warned Japan in 2008 that a strong earthquake could pose a "serious problem" for its nuclear power stations, a US diplomatic cable from the time revealed, Britain's Daily Telegraph reported Wednesday.
The cable leaked to whistle-blower website WikiLeaks suggested that an IAEA expert expressed concern that the Japanese reactors were only designed to withstand magnitude 7.0 tremors.

The IAEA official told a meeting of the G8's Nuclear Safety and Security Group in Tokyo in 2008 that Japan's safety guidelines were outdated, the cable said.
According to the cable, the official raised concern that safety guidelines for seismic safety were only revised three times in the last 35 years.
"Also, the presenter noted recent earthquakes in some cases have exceeded the design basis for some nuclear plants, and that this is a serious problem that is now driving seismic safety work," the cable noted.
