The tremors struck at 9.19 pm local time, was centered near Miyazaki Prefecture on the island of Kyushu. The meteorological agency has also warned of possible waves up to one metre.
A strong earthquake struck the Kyushu region in Japan on Monday, the European Mediterranean Seismological Centre said.
The 6.6 magnitude earthquake, located at a depth of 37 km (23 miles), triggered the country’s meteorological agency to issue a tsunami advisory.
The Japan Meteorological Agency said that the earthquake quake with a preliminary magnitude of 6.9 struck the Kyushu region at 9:19 pm on Monday. After an investigation, the JMA said the quake did not warrant special measures related to seismic activity in the Nankai Trough, according to Reuters.
The meteorological agency has also warned of possible waves up to one metre for the southern prefectures of Miyazaki and Kochi. A 20-centimetre tsunami was later recorded reaching Miyazaki city.
The Nankai Trough, where the Philippine Sea Plate is slipping under the Eurasia Plate at the bottom of the sea off the southwest coast of Japan, produces massive earthquakes about every 100-150 years. Strong quakes nearby are seen as a potential indication that a megaquake could be more likely.
Japan is frequently hit by earthquakes because of its location along the “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific Basin.
