A magnitude 6.7 earthquake rattled Japan late Saturday night leaving crumpled homes and dozens injured.

Aftershocks continued to shake the area and villagers fled their homes to shelters after at least 50 homes collapsed after the initial quake.  Officials say that because the homes are built to withstand feet of heavy snow in the winter, it kept more homes from collapsing.

However, the homes that fell resulted in broken bones after heavy furniture fell on residents as they slept on their tatami floors.

The quake, which struck just west of Nagano at a depth of 3 miles, struck along a very active fault according to the Japan Meteorological Agency.

Officials say most of the residents of the area are elderly and that younger residents are working to care for those who were injured and who lost their homes.
