Tuesday’s quake struck close to the epicenter of the 2011 quake, just 37 kilometers (23 miles) east-southeast of Namie at a depth of 11.4 kilometers (7 miles).
The quake triggered a tsunami warning in Japan’s Fukushima and Miyagi Prefectures, causing the government to urge thousands to seek higher ground amid warnings waves could be up to 3 meters high (10 feet).
“Given the one in 2011 was magnitude 9.0, it was about 1,000 times more powerful than the energy release of this earthquake. For each (degree of) magnitude you go up, it is 32 times the energy of the previous one,” he said.
