A 6.7 magnitude earthquake struck central Japan Saturday night, destroying homes and injuring nearly 40 people.
The quake struck near Nagano, a city in Japan's mountainous central region that hosted the 1998 Winter Olympics, the Associated Press reported. It hit at a depth of about six miles.
Authorities said 39 people had been injured as of Sunday morning, though the numbers had been steadily rising since late Saturday.
At least seven people suffered serious injuries. Many others evacuated and spent Saturday night in a shelter.
