Emergency Management Information System (EMIS) is a system that helps people during an emergency. It's like a computer system that has a lot of information about what to do when something bad happens. For example, EMIS can tell people where the nearest hospital or shelter is, or what supplies they need to gather. It can also give people instructions on how to take care of themselves and their families or provide help to the people around them. EMIS is like a big planning tool that can help people be ready in case of an emergency.
