The document discusses the work of Humanity Road and the Digital Humanitarian Network in monitoring social media for disaster response. Some key points: - Humanity Road monitors 1-3 events daily and has monitored more events than any other organization since 2010. - They co-chair the US Department of Homeland Security's Virtual Social Media Working Group and test new data mining tools. - During disasters, text messages can provide key information when voice networks are down, as seen in events like the New Zealand earthquake and Alabama tornado. - The Digital Humanitarian Network maps social media reports for organizations like UN OCHA to assess damage and needs after events like the Philippines Typhoon Bopha.
