- A massive 8.9 magnitude earthquake and tsunami struck northern Japan on March 11, 2011, causing widespread damage and killing thousands. - At the Fukushima Daiichi nuclear power plant, explosions at reactors caused radiation leaks, forcing the evacuation of 185,000 people from a 20km exclusion zone. - Rescue efforts were underway across devastated coastal areas to search for survivors and deliver aid, but challenges remained from lack of basic infrastructure and the nuclear crisis.

2. Nuclear disaster threat looms over Japan – 2011 march, 14 Anxiety in Japan grows as rescue workers find more bodies Two days after the alarm was first raised about safety at Fukushima Daiichi plant, uncertainty still surrounds the situation on the ground and the status of the three reactors that were functioning at the time of Friday's earthquake and tsunami. Thousands of people are believed to have died, and millions are spending a fourth night without water, food, electricity or gas. More than 500,000 people have been left homeless. People in Minamisanriku fled on Monday amid fears of another tsunami Nearly 185,000 people have been evacuated from a 20km (12 mile) exclusion zone around the plant. The US said it had moved one of its aircraft carriers from the area after detecting low-level radiation 160km offshore. A massive emergency response operation is under way in northern Japan, with world governments and international aid groups coming together to bring relief to the beleaguered island nation. Ninety-one countries and regions and six international organizations have offered assistance, according to the Japanese Foreign Affairs Ministry. A satellite photo of the Fukushima Daiichi plant showed the damage done to reactors 1 and 3, where there was an explosion on Monday

An explosion shook the quake-damaged Japanese nuclear power plant on March 14 and plumes of smoke rose from the building, live television showed. Japan's nuclear safety agency said the blast, at the number 3 reactor at the Fukushima No. 1 plant, was believed to be caused by hydrogen.
