Hopefully the poster will reply themselves but... I think they mean that the nuclear accident, wasn't the biggest disaster that happened that day. It is pretty amazing, that a nuclear accident, that's the biggest accident since Chernobyl, wasn't the biggest disaster that was cause by the tsunami. It is absolutely true, that the impact of the tsunami, and deaths it directly caused, was much bigger than the nuclear accident itself. The nuclear accident itself caused no direct casualties. Its impact has mostly been that on the local population that was evacuated (which has of course caused much pain, and economic disruption).
