Japan's Fukushima Plant: Tsunami Warning and Nuclear Safety

Workers at Japan's Fukushima nuclear plant left quickly on Wednesday. This happened because of a tsunami warning. A big earthquake near Russia caused the warning.

The warning reminded people of a bad event in 2011. Back then, a huge earthquake and tsunami hit Japan. It caused big problems at the Fukushima plant. Many people had to leave their homes.

Now, Japan is still trying to clean up the plant. It's a hard job that will take many years. The country also has to decide how to use nuclear power safely in the future.
