Using a quantitative approach, this study aims to assess Indonesian nurses' perception of their knowledge, skills, and preparedness regarding disaster management.This study was a descriptive comparison in design. The research samples are Indonesian nurses working in medical services and educational institutions. The variables of nurses' preparedness to cope with disaster victims were measured using the Disaster Preparedness Evaluation Tool (DPET), which was electronically distributed to all nurses in Indonesia. Data were analyzed using a statistical descriptive one-way Analysis of Variance (ANOVA) and t-test with a significance level of 95%.In total, 1341 Indonesian nurses completed this survey. The average scores of preparedness to cope with disasters, the ability to recover from disaster, and evaluation of disaster victims were 3.13, 2.53, and 2.46, respectively. In general, nurses surveyed in this study are less prepared for disaster management, and do not understand their roles both during the phase of disaster preparedness, and when coping with a post-disaster situation.Nurses' preparedness and understanding of their roles in coping with disasters are still low in Indonesia. Therefore, their capacity in preparedness, responses, recovery, and evaluation of disasters needs improvement through continuing education. The efforts needed are significant due to potential disasters in Indonesia and adequate nurses resources.
