Tsunami Advisory in Japan After 6.9 Magnitude Earthquake Strikes Southwest

Japan’s Meteorological Agency issued a tsunami advisory late Monday after a 6.9 magnitude earthquake struck off the coast of southwest Japan. The quake, which hit at 9:19 p.m. local time, triggered warnings for Miyazaki and Kochi prefectures on the islands of Kyushu and Shikoku.

Earthquake Details

The earthquake’s epicentre was offshore at a depth of 30 kilometres (18.6 miles), according to Japanese officials. The U.S. Geological Survey recorded a preliminary magnitude of 6.8, aligning closely with Japan’s measurement. Residents in affected areas reported tremors, but no immediate damage was confirmed.

Tsunami Advisory and Precautions

The tsunami advisory estimates waves as high as 1 metre (3.2 feet) in some coastal areas. Authorities have urged residents in Miyazaki and Kochi to evacuate low-lying areas and avoid approaching the sea. Officials recorded waters measuring 20 centimetres (0.7 feet) at Miyazaki Port and anticipated more significant waves.

Japan’s Meteorological Agency warned that coastal activities should be suspended until the advisory is lifted. Public broadcaster NHK confirmed no disruptions in power supply or nuclear plant safety in the region.

Japan’s Earthquake Preparedness

Japan frequently experiences earthquakes due to its location along the Pacific Ring of Fire, a seismic zone with active fault lines and volcanoes. The country has implemented advanced monitoring systems and strict building codes to minimise risks.

Current Status and Updates

As of now, no significant damage or casualties have been reported. Emergency teams remain on standby, monitoring the situation closely. Authorities will provide updates as conditions evolve. Residents should stay tuned to local news channels and official sources for further instructions.

Authorities have advised residents to avoid the sea and coastal areas until the advisory is lifted, according to the country’s meteorological agency on X.

Updates will follow as the situation develops.
