Emergency response aims to provide support immediately following a disaster by mitigating damage, restoring essential services, and caring for those affected. Key aspects of response include coordination, command structures, readiness, information management, security, sectoral management, assessment, logistics, budgeting, and action planning. Response follows a cycle of alert, action, and stand-down phases with ongoing assessment and coordination between organizations. Common challenges include inadequate preparedness, slow response activation, logistical problems, and poor coordination, highlighting the importance of effective warning systems, resource readiness, information management, and inter-organizational coordination for response.
