Strong earthquakes early on Monday hit Japan's north-central region of Ishikawa that was hit on January 1 by a fatal quake. The authorities said there was no danger of a tsunami. There were no reports of damage or injuries.
"A magnitude 5.9 quake hit a northern tip of the Noto Peninsula. Minutes later, a tremor of magnitude 4.8 occurred," said Japan Meteorological Agency.
There was no danger of tsunami from the two earthquakes, it added.
Most public transportation services were operating normally, said the West Japan Railway Co.
No abnormalities were found at two nearby nuclear power plants, stated the Nuclear Regulation Authority after the tremors.
One of them, the Shika plant on the Noto Peninsula, had minor damage, though officials said that did not affect cooling functions of the two reactors. Hokuriku Electric Power Co said there were no power outages.
On January 1, a magnitude 7.6 earthquake hit the Noto Peninsula killed 241 people. Damages still remain and many of the residents had evacuated on the first day of the year.
