This study aimed to investigate Twitter use during natural hazards and pandemics. The included studies reported the role of Twitter in disasters triggered by natural hazards. Electronic databases were used for a comprehensive literature search to identify the records that match the mentioned inclusion criteria published through May 2020. Forty-five articles met the selection criteria and were included in the review. These indicated ten functions of Twitter in disasters, including early warning, dissemination of information, advocacy, assessment, risk communication, public sentiment, geographical analysis, charity, collaboration with influencers and building trust. Preventing the spread of misinformation is one of the most important issues in times of disaster, especially pandemics. Sharing accurate, transparent and prompt information from emergency organizations and governments can help. Moreover, analyzing Twitter data can be a good way to understand the mental state of the community, estimate the number of injured people, estimate the points affected by disasters and model the prevalence of epidemics. Therefore, various groups such as politicians, government, nongovernmental organizations, aid workers and the health system can use this information to plan and implement interventions. Keywords: Twitter; disaster; risk reduction; preparedness; response; recovery 1. Introduction All disasters and emergencies are, by nature, chaotic and dynamic (Guha-Sapir et al. 2016). Disasters triggered by natural hazards change the lives of people in seconds and create physical, emotional and social damage. In such a situation, communication is critical in all phases of disaster management (Mukkamala and Beck 2016). In previous decades, people relied on traditional media such as TV, the radio and newspapers for the news. Sharing information was not easy and quick. In the new era, new technologies have given us the ability to communicate with others quickly and interactively. With rapidly evolving smart device technologies, people can now access information in milliseconds just with one click. Online social media such as Facebook and Twitter play a vital role in disaster management in the world and are recognized as the most popular source for receiving information during disasters (Gray et al. 2016; Avasthi 2017). People themselves are the producers and consumers of messages. The number of social media users worldwide, statistically, was determined from 2010 Journal.
