6.9 Magnitude Earthquake Hits Southwestern Japan, Tsunami Advisory Issued

 

A 6.8-magnitude earthquake struck southwestern Japan late Monday evening, triggering two minor tsunamis in the region. Fortunately, no major damage or injuries have been reported. The quake occurred at 9:19 PM local time (12:19 GMT) at a depth of 36 kilometers, approximately 18 kilometers off the coast of Miyazaki Prefecture in Kyushu, according to the US Geological Survey.

6.9 Magnitude Earthquake Hits Japan: Tsunami Advisory Issued

In response to the earthquake, the Japan Meteorological Agency (JMA) issued a tsunami advisory, warning of potential waves up to one meter (three feet) high. The agency urged residents to stay away from coastal areas, emphasizing that tsunamis can strike multiple times. They advised against entering the sea or approaching the shoreline.

Minor Tsunamis Recorded

Two small tsunamis, measuring approximately 20 centimeters, were observed at ports in the affected areas. Despite the earthquake and tsunami warnings, local media reported no immediate injuries or significant damage. Live footage from the region showed calm seas, and normal operations continued for vessels and traffic.

Japan's Seismic Activity

Situated atop four major tectonic plates along the Pacific "Ring of Fire," Japan is among the most seismically active countries in the world, experiencing about 1,500 earthquakes annually. This accounts for roughly 18% of the world’s total seismic activity. While most of these tremors are mild, their impact can vary based on their location and depth.

Recent Seismic Events and Warnings

This earthquake follows a deadly 7.5-magnitude tremor on Japan's Noto Peninsula on New Year's Day 2024, which claimed nearly 470 lives, many of whom were elderly. In August 2024, the JMA raised concerns about a potential "megaquake" following a 7.1-magnitude tremor. Such a megaquake, associated with the Nankai Trough, an undersea fault line, could trigger massive tsunamis and cause widespread devastation.
