Strong earthquake along the coast of Honshu, Japan
JMA Japan reports a magnitude of 5.8 at a depth of 50 km
Max. intensity : 5- (just below what Er considers a potential serious damaging level)
5- intensity at Asahi-shi Minami-horinouchi*
Earthquake must have been well felt in Tokyo
12 km S Choshi (pop 75,650)
46 km E Narita (pop 100,641) Narita is one of the Tokyo airports
93 km E Tokyo (pop 8,336,599)
Minor damage cannot be excluded in the 5- intensity area
The earthquake occurred at an intermediate depth what means that the intensity is weakened by the depth of the hypocenter

Of course NO tsunami risk at this magnitude
