Nishi-no-shima volcano restarted its eruptive activity on November 20, 2013. Effusion of huge amount of lava continued for two years and original Nishi-no-shima was merged into the huge amount of new lava flow. After the vulcanian eruption on November 17, 2015, no eruption had been observed. Therefore, the Japan Coast Guard conducted hydrographic survey by survey vessels and aircraft in June 2015 and October 2016.
