This app was inspired by the events that occurred after the earthquakes of September 7 and 19, 2017 in Mexico, after this the social networks and the media acted quickly to report incidents in many important places, however, a problem was constantly found, many affected places had no visibility and hardly received help, there were many false reports, collection centers with excess supplies and many where needed, shelters crowded with people and empty shelters, as well as communication problems because the information was not consistent , and sparsely populated or isolated areas had no visibility in any medium. That is why the idea of im4Disasters arises, an application/service that aims to be a unified source, updated in real time by the users themselves, where they can see reports anywhere in the world.
