Japanese manufacturers in the Tohoku region went about business as usual, despite a 7.4 magnitude quake at a depth of 10 kilometers that struck off the shores of Fukushima earlier this morning, reported TechNews.

Tremors from the quake led to a temporary shutdown of Fukushima Daini Nuclear Power Plant, but the plant has been up and running since.

This is the second strong quake to hit the prefecture after the devastating 9.0 magnitude earthquake and tsunami swept over the region in 2011.
