Summary On the evening of July 8, 2000, Miyake-jima erupted. The island’s first eruptions in 17 years continued intermittently after that, with the largest eruption at about 17:30 on August 18; low-temperature, sluggish pyroclastic flows occurred on the 29th. This led to an off-island evacuation order on September 1, the evacuation of residents off the island from the 2nd to the 4th in response, and then long-term living in evacuation facilities for over 4 years due to volcanic gas emissions. The damage directly after a disaster tends to attract the most attention, but inevitably, various problems in daily life arise from individual circumstances, and disparity in recovery occur in the process of recovery from disaster. This survey gathers island residents’ voices in the recovery process and reveals the true state of daily life problems and disparity in recovery that occur therein.

This survey aims to gain knowledge about the eruption and evacuation and about residents’ attitudes before and after returning to the island and problems in daily life to provide the basic materials to understand the ongoing recovery of Miyake Village, as well as sharing the actual situation with the public.

The main survey items are damage to respondent’s home, returning to Miyake-jima, household budget, rebuilding respondent’s home, recovery, and attitudes to natural disasters.
