Timely and accurate disaster information after the earthquake can provide an important basis for the deployment of emergency rescue force, the decision-making of emergency command, and the assessment of earthquake intensity. This paper analyzed the actual need of quickly collecting on-site disaster information after the earthquake, determined the research and development goal of the earthquake disaster information acquisition system based on Android platform. Then it analyzed the business process of the system and designed the system architecture and system client, middle layer, and data layer. Finally, it described in detail the realization of many functions i.e., disaster information and intensity reporting, query management, statistical analysis, etc. The test results verified the applicable value and disaster collection efficiency of the system.
