7.1-MAGNITUDE EARTHQUAKE STRIKES KYUSHU, TSUNAMI ALERT ISSUED

A 7.1-magnitude earthquake struck the island of Kyushu in southwestern Japan on Tuesday at 4.27pm local time, prompting authorities to issue a tsunami alert. The Japan Meteorological Agency recorded the tremor at the maximum level seven on Japan's Shindo scale of ground shaking intensity. The agency warned that tsunami waves could reach up to one metre in height across coastal areas, with broadcaster NHK reporting that waves of that magnitude may already have been recorded.

The earthquake caused significant disruption to power supplies in the region. According to Kyushu Electric Power, approximately 45,000 households and facilities lost electricity in the Kumamoto region. The Nuclear Regulation Authority stated that no immediate abnormalities had been detected at nuclear power plants in the affected area.

Japan's earthquake monitoring and response systems activated swiftly following the tremor. The rapid dissemination of tsunami warnings through official channels and media outlets enabled coastal residents to receive advance notice of potential wave activity. The extent of any damage or casualties remained under assessment in the hours following the earthquake.
