论文摘要
社交媒体平台已在自然灾害中广泛使用。但是，大多数先前的工作缺乏专注于研究其在全球南部灾难中的用法，在全球南部，互联网访问和社交媒体利用与发展中国家不同。在本文中，我们研究了如何在2017年9月19日袭击墨西哥的7.1震荡地震后使用社交媒体（称为19S地震）。我们对参与者在＃19S之后如何利用社交媒体平台的分析进行了分析。我们的研究扩展了对危机信息学的调查：1）研究参与者如何在全球南部国家的自然灾害之后使用不同的社交媒体平台； 2）发现个人如何使用地面公民方法开发自己的流程来验证新闻报道； 3）揭示人们如何开发自己的机制来处理过时的信息。为此，我们调查了356人。此外，我们分析了一个月的活动：Facebook（12,606个帖子），Twitter（2,909,109条推文），Slack（28,782条消息）和Github（2,602个提交）。这项工作提供了有关用户行为的多平台观点，以协调救济工作，减少错误信息的传播并处理过时的信息，这对于帮助救济工作的协调和效率至关重要。最后，根据我们的发现，我们为技术设计提出了建议，以提高社交媒体在危机响应工作中的有效性，并减轻跨社交媒体平台的错误信息传播。
Social media platforms have been extensively used during natural disasters. However, most prior work has lacked focus on studying their usage during disasters in the Global South, where Internet access and social media utilization differs from developing countries. In this paper, we study how social media was used in the aftermath of the 7.1-magnitude earthquake that hit Mexico on September 19 of 2017 (known as the #19S earthquake). We conduct an analysis of how participants utilized social media platforms in the #19S aftermath. Our research extends investigations of crisis informatics by: 1) examining how participants used different social media platforms in the aftermath of a natural disaster in a Global South country; 2) uncovering how individuals developed their own processes to verify news reports using an on-the-ground citizen approach; 3) revealing how people developed their own mechanisms to deal with outdated information. For this, we surveyed 356 people. Additionally, we analyze one month of activity from: Facebook (12,606 posts), Twitter (2,909,109 tweets), Slack (28,782 messages), and GitHub (2,602 commits). This work offers a multi-platform view on user behavior to coordinate relief efforts, reduce the spread of misinformation and deal with obsolete information which seems to have been essential to help in the coordination and efficiency of relief efforts. Finally, based on our findings, we make recommendations for technology design to improve the effectiveness of social media use during crisis response efforts and mitigate the spread of misinformation across social media platforms.
