12 injured after 7.8-magnitude earthquake shakes Japan

At least 12 people incurred minor injuries as businesses returned to normal a day after a massive 7.8-magnitude earthquake, which originated near remote Japanese islands, shook the country.

The U.S. Geological Survey detected the epicentre of Saturday's quake to be 189 kilometres off the Ogasawara islands at a depth of 421 miles. However, no tsunami warnings were issued, reported Fox News.

The quake was also followed by a 6.4-magnitude temblor on Sunday morning that struck Japan's Izu islands, north of the Ogasawaras.
