Tsunamis of nearly 2 feet in height were reported along the Japanese coast from the magnitude 7.3 jolt. There were no reports of significant damage on land.
The U.S. Geological Survey says the quake was centered about 230 miles off the main island of Honshu at a depth of about 6 miles.
The same area suffered more than 18,000 fatalities when in 2011 when one of the most powerful earthquakes in Earth’s history created a titanic tsunami that crashed into the Fukushima coast.
Beyond the massive destruction to communities along the coast, the tsunami also resulted in meltdowns of three reactors at Japan’s Fukushima Daiichi nuclear power plant.
Operators have been unable to contain the resulting contamination despite two and a half years of efforts.
