An earthquake of 6 degrees on Richter Scale struck off the coast of northern Japan for the second straight day. It hit 167 kilometres from Miyako city, the US Geological Survey said. No victims or damage have been reported so far.
The jolt came one day after a 5.3 magnitude earthquake struck northeastern Japan off the coast of Ibaraki prefecture, just south of Fukushima.

Japan sits at the junction of four tectonic plates and experiences a number of relatively violent quakes every year, but rigid building codes and their strict enforcement mean even strong tremors often do little damage.
