Tokyo, Apr 13 (EFE).- A magnitude-6.3 earthquake rocked western Japan early Saturday, injuring 23 people and causing minor damage to buildings, although authorities did not issue a tsunami alert.
The temblor struck at 5:33 a.m. and was centered near Awaji Island at a depth of 15 kilometers (9 miles), Japan's meteorological agency said.
For its part, the National Police Agency said the earthquake left 23 people injured in five different prefectures, 14 of them in Hyogo, where Awaji Island is located.
No problems were observed at the numerous nuclear power plants in western Japan, including Oi in Fukui prefecture, the only such facility still in operation nationwide after the Fukushima Daiichi nuclear disaster that followed the devastating March 11, 2011, earthquake and tsunami.
Airports, railway lines and large infrastructure in western Japan also did not suffer significant damage.
On Jan. 17, 1995, a magnitude-6.8 earthquake that struck near Awaji Island caused massive damage, especially in the nearby city of Kobe and its outskirts, and was blamed for more than 6,000 deaths.
Saturday's earthquake was the most powerful in that region of the country since the deadly 1995 temblor.
