Japan was hit by a 6.5-magnitude earthquake on Saturday, just east of Namie, Fukushima a few minutes past 0300 local time. The quake was followed abruptly by a 4.6-magnitude aftershock less than an hour later, according to the US Geological Survey.

The epicenter of the first quake was offshore - 129 km off the region of Fukushima, while the aftershock was recorded to have a distance of 108km off the region. A tsunami warning was initially issued by the Japan Meteorological Agency (JMA), which it later modified to tsunami advisories for regions near the coastline, including the Fukushima prefecture, where Japan's Daiichi nuclear power plant is located.

Fukushima's Daiichi Nuclear Power Plant was the core of Japan's nuclear radiation calamity which lasted months after the country was hit by the tsunami catastrophe in 2011.

The quake has raised alarms as it inevitably brought about memories of the past catastrophic disaster which was one of the worst to ever hit Japan, claiming tens of thousands of lives in March of 2011.

To the relief of many, the JMA has already cancelled all the tsunami warnings, and no major damage has been reported.

The Japan Meteorological Agency categorized the quake to have had a 6.8 magnitude, whereas the USGS later downgraded its estimate to 6.5.

In related news, Tokyo Electric Power Co., the Japanese company responsible for the controversial Daiichi Nuclear Power Plant, has braced itself for a typhoon that stormed the Fukushima region Friday night.

Neoguri, the typhoon which entered the Japan waters earlier this week has already been accountable for three deaths as it pounded territories of the country for days.

It was reported, however, that the storm has already significantly weakened as it entered the Fukushima region later this week.
