Social media plays an increasing role in how people communicate. Whether in the middle of a disaster or in everyday situations, more are exchanging information by using the Internet, texting, Facebook, Twitter, Instagram, Flickr, YouTube or using apps such as WhatsApp and Snapchat.
Preparedness is defined by DHS/FEMA as "a continuous cycle of planning, organizing, training, equipping, exercising, evaluating, and taking corrective action in an effort to ensure effective coordination during incident response." This cycle is one element of a broader National Preparedness System to prevent, respond to, and recover from natural disasters, acts of terrorism, and other disasters. Planning makes it possible to manage the entire life cycle of a potential crisis.
