TOKYO, April 27 (Bernama-Kyodo) -- A quake with a magnitude of 6.2 struck Japan's Hokkaido on Monday, with no tsunami warning issued, Japan Meteorological Agency (JMA) said.
The 5.24 a.m. quake registered upper 5 on the Japanese seismic intensity scale of 7 in the Tokachi region of the northern main island and occurred at a depth of about 83 kilometres, Kyodo news reported.
There were no immediate reports of injuries.
Upper 5 is described as the level at which people find it difficult to walk without holding on to something.
No abnormalities were observed at the Tomari nuclear power plant, according to Hokkaido Electric Power Co.
The quake came in the middle of a weeklong advisory by the weather agency warning of an increased risk of a powerful quake following a magnitude 7.7 earthquake that struck the northeastern Japanese prefecture of Aomori exactly a week earlier.
Hokkaido is among the seven areas where caution has been advised.
The earthquake's magnitude was initially estimated to be 6.1 but was later revised up.
