Japan: Tsunami Warning After A Magnitude 7.2 Submarine Earthquake

A magnitude 7.2 underwater earthquake occurred just off the northeastern coast of Japan on Saturday, according to the Japan Meteorological Agency (JMA), which issued a warning against waves of about one meter. The earthquake, also felt in Tokyo, occurred at 6:09 p.m. (10:09 a.m. French time) at a depth of 60 kilometers under the Pacific Ocean and just in front of the Miyagi department, according to the JMA. The United States Institute of Geological Studies (USGS) estimated the magnitude of the earthquake to be 7.0.

No damage to Miyagi was immediately reported, and electricity suppliers were assessing the situation of nuclear power plants in the area, according to Japanese media. This powerful earthquake comes as Japan has just marked the tenth anniversary of the triple disaster of March 11, 2011 which ravaged the northeast of the country: a magnitude 9.0 earthquake was followed by a gigantic and very deadly tsunami , which also triggered the nuclear accident in Fukushima.

Last month, the same region, Tohoku, which includes the departments of Fukushima and Miyagi in particular, was also hit by an undersea earthquake of magnitude 7.3, which did not cause a tsunami. Around 100 people were injured while material damage was limited. Located at the crossroads of several large tectonic plates, Japan is almost daily affected by earthquakes. But the country has strict building standards so that its buildings are able to withstand strong shaking.
