Social media plays an important role in emergencies by facilitating information exchange, but it also presents risks and challenges. When emergencies strike, social media becomes a key tool for actors like government agencies and NGOs to disseminate information to the public and understand evolving needs. However, determining who the trusted sources and influencers are during crises can be difficult with the large volumes of user-generated content on platforms. There is also a lack of coordination between responders using social media, leading to an "organized anarchy" response. Proper use of social media in emergencies requires understanding information ecosystems and who may be missing from exchanges.
