Workers at Japan’s embattled nuclear power plant in Fukushima were recently seen getting evacuated during the early hours of Wednesday.

This was right after warning bells for a tsunami were issued across the nation. As per the plant’s operator, 4000 of its workers were evacuated immediately, and there were no abnormalities detected so far.

The news comes after a massive 8.7 magnitude earthquake struck off the eastern coast of Russia, giving rise to warnings across the entire Pacific.

For so many, the warning was likely to bring back memories of one of the most devastating nuclear disasters that the world had witnessed. In March of 2011, the country was struck by a massive 9.0 magnitude earthquake and which gave rise to a huge tsunami, which led to the deaths of more than 18,000 people.

Authorities shared how they did not take any risk this time around as they didn’t wish to see a repeat of the mega disaster that arose on March 11, 2011. This is where the Great East Japan Earthquake hit the east of the city of Sendai, just 97km north of the power plant.

Reactor buildings at the site were damaged due to a massive hydrogen explosion caused by the earthquake and tsunami. This knocked out all cooling systems to the reactors, while three of them underwent a massive meltdown.
