Japan warns of potential ‘megaquake’ in Nankai Trough following 7.1-magnitude tremor

Japan issued a warning about the possibility of a “megaquake” after a 7.1-magnitude earthquake struck off its southern coast without causing serious damage. The earthquake occurred off the coast of Miyazaki Prefecture, injuring three people but causing no major damage. Seismologists are analyzing whether the quake affected the nearby Nankai Trough, which could lead to devastating earthquakes. The Japan Meteorological Agency issued a “mega earthquake caution,” urging increased vigilance for the next week. Tsunami advisories were issued for coastal areas, with waves detected along the southern coast of Kyushu and the nearby island of Shikoku. Some damage, such as landslides, collapsed walls, and broken windows, was reported, but nuclear reactors remained safe. Japan is prone to earthquakes due to its location on the Pacific ‘Ring of Fire’. In 2011, a 9.0-magnitude earthquake and tsunami triggered the Fukushima nuclear disaster. The recent earthquake serves as a reminder of the country’s vulnerability to seismic activity, prompting calls for increased preparedness among residents. Japan’s history of earthquakes highlights the importance of being ready for future disasters.
