Strong earthquake out in the sea of the Kagoshima prefecture, Japan (Ryukyu Islands)

Update 14:23 UTC : The hypocenter of this earthquake was right in the subduction slope and very shallow (8 km), which may explain in part why it was felt as strong by the people living and working on the nearby islands.

Update 13:52 UTC : There is of course NO tsunami danger for this earthquake

This earthquake was very well felt in the Kagoshima prefecture but was not really dangerous with a maximum JMA3 intensity shaking. Based on our experience with Japanese earthquakes, earthquake-report.com considers JMA 5+ intensity as a potentially dangerous shaking.
