This map shows the 7.3 magnitude quake that just hit off Japan’s coast

A strong, 7.3 magnitude earthquake was recorded off of Japan's eastern coast, along Fukushima prefecture, which was devastated in March 2011 by an offshore earthquake of magnitude 9.0. The U.S. Geological Service says the quake hit about 200 miles offshore and struck 6.2 miles deep. In an eerie echo of the March 2011 disaster, Japan quickly issued a tsunami advisory – although the notice falls short of an official warning and so is not considered as serious.

So far, there is no reason to believe that this quake will cause serious damage. This map shows the location of the quake:

Here is a map showing the areas under tsunami advisory: Fukushima prefecture, the same place hit in March 2011, as well as Miyagi, Iwate, Ibaraki and parts of Chiba. Again, the region is not under threat as it was two and a half years ago, but this is a reminder of both the devastation from 2011 and, more importantly, the fact that this part of Japan is still at risk from major seismic events.

The 2011 quake was only 109 miles off of Japan's Fukushima coast and hit at a depth of 18.6 miles.
