“…The method can update the template after an earthquake using the information in the earthquake model to automatically draw an emergency map. Finally, the reliability of this method is verified by case study [14]. Ahmadzadeh et al (2019) evaluated the performance of earthquake stress command headquarters in Alborz Medical Sciences University in earthquake accident and disaster risk management, and found that the command headquarters responded timely and could make effective decisions [15].…”

“…Finally, it is found that the system can respond more quickly and reasonably [13]. Xu et al (2020) proposed a mapping method of template matching in order to quickly make earthquake emergency map. The method can update the template after an earthquake using the information in the earthquake model to automatically draw an emergency map.…”

To solve the problems of slow information acquisition, low processing efficiency, weak information storage and communication ability in earthquake rescue, an earthquake emergency command system on the basis of cloud computing and Internet of Things (IoT) is designed. First, the cloud computing technology is introduced, and the traditional earthquake emergency command system built by cloud computing and the Internet of things is analyzed. Then, based on the satellite remote sensing data, the characteristics of the middle-wave infrared remote sensing data before and after the recent earthquakes in China are explored. Subsequently, a new earthquake emergency command system is built based on cloud computing and Internet of things technology along with the data from the satellite middle-wave infrared remote sensing. Finally, the feasibility of the system is evaluated. The results show that the surface radiation changes significantly before the earthquake, the infrared brightness temperature difference value also fluctuates violently, and the abnormal area will gradually get closer to the epicenter as time goes by. The peak value of the relative power spectrum in the earthquake is more than 9 times of the average value in the normal time. In conclusion, the evaluation result of the emergency command system based on satellite remote sensing data, cloud computing, and Internet of things is good, suggesting satellite infrared remote sensing data can be applied to earthquake prediction, and the earthquake emergency command system constructed combining cloud computing and Internet of things technology has a good feasibility.

“…The effects of maps and best practices for incorporating them vary depending on the receiving audience (MacPherson‐Krutsky et al., 2020; Xu et al., 2020) and remain largely understudied (Klockow‐McClain et al., 2020; Lindell, 2020), especially in a college campus setting where students receive alerts for a variety of hazards from a singular source. To this end, we evaluate the effect of maps supplementing written text in mobile emergency alerts for two different hazards on students’ perceptions of risk, crisis efficacy, behavioural intention, message understanding, and trust in the source and expand upon the existing pool of research focusing on alerts inclusive of maps.…”

Emergency alerts are typically sent through mobile devices and email and are a means by which to notify students of threats or hazards on campus. Alerts that include maps help illustrate the significance of a threat and improve understanding when designed correctly. This study of a college campus examines how maps can clarify who should take protective action by specifying the location of the threat in relation to the user, and whether maps affect risk perception, intended action, and trust in the message source. Results indicate a significant difference in perceptions of risk susceptibility between participants exposed to a long‐distance map, a short‐distance map, and no map, and participants exposed to the shooting condition reported significantly higher measures of negative emotions, risk susceptibility, risk severity, and behavioural intention. Findings indicate that while personalized maps improve risk susceptibility, they cannot work alone in affecting other message response factors and may be most useful when paired with highly specific warning messages. The results of this study are useful to practitioners developing or improving emergency alert systems.

“…Most of the traditional emergency maps are oriented to sudden natural disasters, of which the service objects typically are the government emergency management department and the relevant institutions. They are mostly applied to assist with scheduling and distribution of emergency resources, the generation of emergency plans, and the deployment of management work (Katzburg et al 2020;Xu et al 2020b). By comparison with a major emergency, a public health emergency has higher requirements for efficiency of information disclosure and cooperation between the government and the public due to its broader and acuter impacts on the public life.…”

“…Kerkvoorde et al (2018) evaluated the effectiveness of flood risk network map design on public understanding. Xu et al (2020b) discussed the design of maps for earthquake emergencies based on audience theory. In brief, previous studies primarily focus on emergency map applications in disaster hazard analysis and are oriented to professionals or decision-makers.…”
