分享訊息對於災難的發生是至關重要的，訊息傳遞越快，災難也回復速度得越快。因此，此研究目的在於觀察引響推特使用者分享災難訊息的因素。過往大多數研究都在評估虛擬社區，而此研究則是專注在社群媒體。此外，我們測試個人、環境、訊息平台等不同因素，個人跟環境因素已經有許多學者去做研究，但訊息平台文獻是相對鮮少的。
資料是使用谷歌(google)問卷進行網路蒐集，回收350份問卷但只有257份為有效問卷，採用結構方程模型(SEM)來對此網路資料進行分析，結果顯示個人因素中的個人預期產出和利他主義思想，對分享災難訊息的動機有顯著的影響。此研究還發現環境因素中的社群認同對分享、搜尋頻率也有顯著影響，但對於分享災難訊息並無顯著影響。此外，訊息平台對於災難訊息分享也有正面的影響。最終，最後一個對分享災難訊息有正面影響的是雅加達推特用戶的分享行為。

Information sharing has now become critically alert of disaster news spreading. The more faster the information is obtained, the disaster recovery will be done more briskly. Therefore, this study examines factors that influence twitter users in disaster information sharing. Most of the previous studies evaluated on virtual community, whereas in this study, we adjust on social media. We tested personal, environmental and information platform factors. In terms of personal and environmental factors, there a lot of research that has addressed the issues, while there are still plenty of them that are using information platforms as their main issues of literature.
Google form collected the data from online survey. Three hundred and fifty data were collected, but only 257 data were valid. We used Structural Equation modeling (SEM) to analyze the data from online survey. The result suggests that personal outcome expectation and altruism from personal factors, as well as community identification from environmental factors, have significant effect on intention of disaster information sharing. However, the amount of sharing participant, frequency of sharing, and searching information do not have significant effect on disaster information sharing. Moreover, information platform also positively influences disaster information sharing. At last, the final result is the intention of disaster information sharing positively influences its behavior of Jakarta twitter users.
