The memories of past disaster experiences tend to fade out quickly. Survivors do not want to keep horrible memories, and try to forget it. Although the transference of lessons learnt through past disaster experience is considered as one of ways to motivate people to take disaster preventive action, the mechanism of how the personal memory form collective memory and transfer to other generation/region is still not clear. In this study, we focus on the memory of earthquake disaster in different region, Turkey, Taiwan and Indonesia. Through field studies we try to find out what kind of memory do people talk as personal memory, and how those personal memory form collective memory and will be transferred.
