Role of Social Media in Earthquake: A Systematic Review

Context: 

Social networks can perform a peculiar role in people'scommunication in the case of crisis and disaster. These media are interactive, digital, or mobile-based tools. Accordingly, the present study aimed to assess the role of social media in earthquakes.

Evidence Acquisition:

In this current systematic review, a query was conducted on such databases as Embase, Web of Science, Scopus, and Cochrane for articles in English language, based on the required criteria from 2000 to 2019 regarding the role of social media in disaster. As a result, 13,924 studies were retrieved, among which 3,963 were deleted due to duplication. Finally, among 244 selected articles, 19 full-text articles were analyzed.

In the present research, 19 studies were thoroughly reviewed. The findings were assigned to four main categories (identification, notification, requests, as well as storage and retrieval of information) with 12 sub-topics. Most of the main topics and subsets were as follows: medical and food needs, information about the accident, as well as medical and relief services, efforts to save lives, the amount of damage, problems and limitations, post-crisis measures, such as keeping calm, reducing anxiety, avoiding high-risk areas, asking for financial assistance, as well as using the information to provide relief and map the affected areas and evacuation centers.

Considering the behavior of people in different geographical locations in the earthquake crisis, it seems that the case studyof how to use social media in disaster management carries profound implications for modeling and localizing the cases in related disaster management institutions of many different countries, such as Iran.
