Miyazaki City, Jan. 13 (BNA): A magnitude 6.9 earthquake struck southern Japan’s Kyushu region on Monday at 9:19 p.m. (0019 GMT), with its epicentre in the sea off Miyazaki city, according to the Japan Meteorological Agency (JMA).

Following the quake, tsunami advisories for waves up to one metre were issued for Miyazaki and Kochi prefectures. A 20-centimetre tsunami was recorded in Miyazaki city, but all advisories were lifted by 0250 GMT.

The quake did not require special measures related to seismic activity in the Nankai Trough, a zone known for generating massive earthquakes every 100–150 years, Reuters reported.

The agency had previously issued a week-long advisory in August, warning of a "relatively higher chance" of a megaquake after a magnitude 7.1 earthquake struck the southwest.

NHK reported no abnormalities at the Ikata Nuclear Power Plant in western Japan or the Sendai Nuclear Power Plant in Kagoshima prefecture, the two plants closest to the affected area.
