A strong earthquake measuring magnitude 9 occurred along the Nankai Trough on the Pacific at XX p.m. on X day, leading the Japan Meteorological Agency to give tsunami warning in prefectures along the Pacific coast.

Tremors with an intensity of lower 7 on the Japanese scale were observed in Kochi, Wakayama and Shizuoka prefectures, the JMA said. No casualties were reported as of @@ a.m. on Y day.

The JMA said it would release information about the status of seismic activity related to a potential Nankai Trough earthquake every evening for a week, noting that the likelihood of the long-anticipated quake has become relatively higher than usual. The information explains the status of quakes and crustal deformation in the assumed epicenter area.

The megaquake advisory covers 707 municipalities in 29 prefectures mainly on the nation’s Pacific side from Ibaraki to Okinawa prefectures, calling for residents to be aware of possible quakes for at least one week and to be ready to evacuate immediately if an earthquake occurs.
