Powerful Quake Kills At Least 7, Paralyses Japan's Hokkaido

A powerful earthquake left at least seven people dead, more than 100 injured and dozens missing on Hokkaido.

The death toll likely to rise as rescuers dig through mud and rubble in search of victims.

The powerful magnitude 6.7 quake, the latest episode in a miserable summer of natural disasters in Japan, knocked out power to all of hokkaido's 5.3 million residents, paralysing the major island, for the first time since Hokkaido Electric Power Co was created in 1951.

Hokkaido electric is now scrambling to get power restored to households, factories and other customers, even as rescuers bring in heavy machinery and digging equipment to search for survivors that may be trapped in stricken buildings or under landslide debris.
