After the earthquake of September 19, 2017, more than a hundred volunteers met at the Centro Cultural Horizontal, in the Roma neighborhood of Mexico City. They built a platform called #Verificado19S to verify and organize information for citizen relief. One volunteer told El Financiero: “Todo esto nació como una forma de organización civil” (All of this was born as a form of civil organization).
Reports arrived through forms and WhatsApp groups. Networks of volunteers checked them by telephone and on site. Urgent needs were posted on Twitter.
