Question

Quizplus · Accepted Answer

The primary cause of the Fukushima nuclear accident was a record-breaking tsunami, triggered by a 9.0 magnitude earthquake, that caused extensive damage to the plant's cooling system and ultimately led to the meltdown of three nuclear reactors. While poor design and human error did play a role in the accident, the tsunami was the primary cause. There is no evidence that the accident was caused by a terrorist attack.
