Quake-hit Japan on alert for ‘Big One’
TOKYO: Seismologists yesterday warned Japan to stay vigilant for the next “Big One” after a powerful 7.8-magnitude earthquake hit off the coast of the quake-prone nation, injuring a dozen people.
Buildings swayed for about a minute in Tokyo and its vicinity on Saturday night as the quake struck a remote spot in the Pacific Ocean about 874km south of the capital, the US Geological Survey said.
Its epicentre was a deep 676km below the Earth’s surface, said Koji Nakamura (pic- tured) from the Meteorological Agency.
Twelve people were injured, including a 56-year-old man who had ribs broken but no one was killed, an official of the Tokyo Fire Department and local media said yesterday.
Saturday’s quake was the second sizeable tremor Tokyo has experienced in a week.
“I can say Japan is in an active stage now,” said Toshiyasu Nagao, head of Earthquake Prediction Research Centre at Tokai University.
“We should be vigilant.”
