A 6.9-magnitude earthquakestruck off Japan’s Honshu island on Tuesday, triggering tsunami waves and bringing back traumatic memories for locals of the devastating 2011 Fukushima disaster.Residents in Fukushima Prefecture braced for the worst after a tsunami warning was issued early Tuesday morning — along the same stretch of coast devastated by enormous waves five years ago.
Earthquakes are common in Japan. The most recent was a6.2 magnitude in late October near Kurayoshi, a city to the west of Osaka, which caused a handful of injuries.
“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.
