Facebook is an incredibly useful tool for gathering and sharing information, especially during disasters and emergencies. Many Emergency Management agencies maintain a virtual presence through Facebook.
National Emergency Management Resource Center (NEMRC) – This group is composed of Emergency Managers from all over the world, and works hard to keep country-level bias out of the conversation. You will be required to answer questions about your involvement in Emergency Management before being allowed entrance. Once you are in, the expectation is that your behaviour will be no different than if you were representing your organization in an EOC. ***DISCLOSURE: I am an Administrator for this group and one of the people responsible for setting and maintaining the group norms.
