Shake and Wave: Japan's Earthquake and Tsunami Alert

On Monday evening, Japan experienced a strong earthquake with an initial magnitude of 6. 9, later revised to 6. 6. The quake struck the southwestern region of the country, specifically in the Kyushu prefecture. Despite the initial high magnitude estimate, no major damage was reported. However, coastal residents were advised to evacuate as a precautionary measure against potential tsunamis. The Japan Meteorological Agency issued a tsunami advisory for Miyazaki prefecture and the nearby Kochi prefecture on the Shikoku island. The advisory was lifted before midnight after the tsunami waves, which were estimated to reach up to 1 meter, didn't cause significant impact. The highest wave detected was 20 centimeters at Miyazaki Port.One minor injury was reported in Kyushu, where a man fell down some stairs. Public transportation was briefly disrupted, with trains stopping at Miyazaki Station. Despite the quake's strength, electric power and nuclear plants in the area remained unaffected. Japan's frequent earthquakes are due to its location on the "Ring of Fire, " a zone known for its volcanic activity and fault lines. Experts from the meteorological agency met to assess any connection between this quake and potential major quakes in the Nankai Trough region. They decided not to take immediate extraordinary measures, as the area has experienced significant seismic activity in the past, including a deadly quake in 1946.
