Central Japan hit by powerful earthquake

The damage from an overnight earthquake in a mountainous area of central Japan that hosted the 1998 winter Olympics proved more extensive than initially thought.

A daylight assessment Sunday found at least 50 homes destroyed in two villages, and 41 people injured across the region, including seven seriously, mostly with broken bones, officials said.

No deaths reported

The magnitude-6.7 earthquake struck shortly after 10 p.m. Saturday west of Nagano City at a depth of 5 kilometers, the Japan Meteorological Agency said. The agency revised the magnitude and depth from initial estimates.
