Japan Issues First Ever Mega Earthquake Warning
The earthquake occurred off Miyazaki Prefecture at 4:42 p.m. local time (3:42 a.m. ET) at a depth of about 18 miles, the Japan Meteorological Agency said.
TOKYO — Japan issued its first warning Thursday about the possibility of a long-feared "megaquake" after a powerful 7.1-magnitude temblor struck off its southern coast, sparking a tsunami advisory but no immediate reports of serious damage or injuries. The meteorological agency ultimately issued what it called a "mega earthquake caution," assessing that the possibility of a large quake was relatively higher than usual but not that one would definitely occur in the near future. Tsunami waves of up to 1.6 feet were detected along parts of Kyushu’s southern coast and the nearby island of Shikoku about a half hour after the quake struck.
