A massive 7.2 magnitude earthquake shook Japan and triggered a 1-meter tsunami warning for the entire northeast coast of Japan. The earthquake was centered 34 kilometers east of the Ishinomaki with a depth of 60 kilometers. The quake shook the buildings of Tokyo, which is hundreds of miles from the epicenter, lasted for 30 seconds.

According to the Japan Meteorological Agency, the epicenter was identified to be 35 miles below the Miyagi Prefecture’s ocean floor. The authorities soon sprang into action and warned the Japanese citizens of a possible tsunami of about 3 feet, but soon lifted the warning. According to Japan public broadcaster NHK, only a handful people have been slightly injured and no casualties have been reported.

Miyagi, which is just north of Fukushima, reported a power outage. Fukushima is the region where huge nuclear facilities are housed. Thankfully after the quake the Japan Nuclear Regulation Authority reported that no abnormalities have been registered at the Fukushima’s nuclear faculties, including the battered Fukushima Daiichi plant, the Onagawa nuclear plant and other experimental nuclear facilities and rectors.

Tokyo Electric Power Company which manages the disabled and fractured plants in Fukushima announced on twitter that it has not come across a damage so far in the plant. Meanwhile, Tohoku Electric took to Twitter to announce that it is in the process of identifying the nuclear power facility’s status.

The earthquake on Saturday came just a week after the 10th anniversary of the 2011 earthquake and tsunami that destroyed the Fukushima Prefecture and led to the nuclear meltdown of three nuclear power plants. Over 1,50,000 evacuees lost their homes, 1,20,000 buildings came tumbling down, taking the total financial damage to about $199 billion, while the total economic cost reaching up to $235 billion according to World Bank’s estimates. It is still one of the costliest natural calamities in the world’s history.

The devastating calamity took the life of over 15,800 people as of June, 2016 with more than 2,500 people still missing. One of the most devastating consequence of the calamity was cooling system failure at the Fukushima Daiichi Nuclear Power Plant. This resulted to level-7 nuclear meltdown (the worst it can get).

It should be noted that another earthquake of 7.1 magnitude was reported just last month in the same region. The earthquake left a dozen people injured but thankfully no tsunami alert was issued and no casualties were reported.

As of today, Japan accounts for more approximately 20% of the overall earthquakes struck around the world that have a magnitude of 6.0 or higher. The country is quake prone to such an extent that over 1,500 earthquakes strike the nation every year and minor tremors are an everyday affair. As to the why the island country is prone to earthquakes, the scientists have attributed it to the ‘ring of fire’. Japan is located along the Ring of Fire, a region on the pacific which is the most active belt of earthquake in the globe. To put it into perspective, the ring of fire accounts for almost 90% of the overall earthquakes in the world and houses 75% of the world’s most active as well as dormant volcanoes.
