第二頁中有這段話：
接著我們來看看福島核電廠的狀況。在日本所發生的地震，它的強度其實遠遠超過這個核電廠當初建造時所能抵擋的地震強度。（芮氏地震規模是對數級數，8.2 級和 8.9 級之間的能量差距是 5 倍，不是 0.7 倍）
原文中亦有：
The following is a summary of the main facts. The earthquake that hit Japan was several times more powerful than the worst earthquake the nuclear power plant was built for (the Richter scale works logarithmically; for example the difference between an 8.2 and the 8.9 that happened is 5 times, not 0.7).

關於這點我不知道該如何吐槽了，根據換算(我用的是10^(1.5*級數差距))，0.7級的差異應該是11倍吧= =||||
有錯的話請多指教。
