The earthquake alert is a warning message the public will receive when an earthquake occurs in Taiwan. Although the information distribution unit is the central government, the core of the construction lacks a user perspective. Through affinity mapping of user experience investigation, it is found that most users want to receive information about "main earthquake", "warning type", "extended disaster", "refuge instruction", "post-earthquake related information", and "status report". Next, the three designers are asked to follow the above information requirements and design earthquake alert interfaces. Thirdly, the interface will be adjusted after expert interviews, interface evaluation feedback, and testing. Finally, the formal test passed the usability test of 35 subjects. The research concluded that the information content could be divided into three types: "disaster information", "user guidance", and "the subsequent current situation and others” and found that the information process should be divided into (1) before and during the earthquake (2) the first half of the earthquake (3) the second half of the earthquake (4) the second half of the earthquake. This study has summarized seven critical points of the design interface, including (1) simple and straightforward important text, (2) color discrimination of earthquake levels, (3) simple images related to information transmission, (4) enlargement of important text and images in crises (5) page flashing display can improve the attractiveness to users (6) the design of buttons should have guiding functions (7) complex information can be simplified through links to reduce the burden of users.
