After an eruption at Kuchinoerabujima on May 29, 2015, Japan Meteorological Agency (JMA) upgraded the alert level up to 5 (maximum, evacuation), all the residents evacuated from the island volcano. I addition to this, swarm of volcanic earthquakes associated with rapid inflation of the ground of Sakurajima pushed JMA to upgrade the alert level to 4 (evacuation of residents requiring assistance) and 77 residents evacuated from 3 villages of Sakurajima. In this paper, I will describe volcanic activity of the volcanoes and evacuation, and discuss on further advance of research to mitigate volcanic hazards.
