The 1911 Kikai Island earthquake (喜界島地震, Kikai-jima Jishin) occurred on June 15 at 23:26 local time (14:26 UTC).

[3] The earthquake occurred near the northern end of the deepest region in Ryukyu Trench.

However, due to the instrumental precision of that time, the location of the hypocenter was just an approximation, and estimations differ.

[7][8] This earthquake could be felt as far as in Shanghai, China, Tainan, Taiwan (then under Japanese rule), and Fukushima, Japan.

[8][9] The earthquake triggered a tsunami which was recorded on Kikai Island and Amami Ōshima.
