In the aftermath of a disaster, information can mean the difference between life and death. After the earthquake hit in Mexico City, it wasn’t just buildings that collapsed, the normal lines of communication that connect the city did as well. It was in this dangerous state of confusion and chaos that a group of friends using WhatsApp to share information ended up creating what later became known as Verificado19s, a spontaneous, grassroots initiative that consisted of a vast network of volunteers that traveled throughout the city to gather and verify information.
