The damaged Fukushima nuclear power plant was evacuated after the tsunami alert was issued. Japan's meteorological agency issued an alert for a tsunami of 50 cm. The epicenter of the quake is believed to be at a depth of 10km (6.2 miles) of the Pacific Ocean off the coast of island Honshu, according to the US Geological Agency. This is more or less the same area as the March quake. [Watch the video of the Japan tsunami in March here]

Japan is still recovering from the massive earthquake and a deadly tsunami that wreaked havoc in Japan this March with thousands dead and rendering many homeless. As many as 23,000 people died with thousands others displaced.
