The response to a crisis or other urgent situation is a complex process that reflects and reconciles the concerns, interests, and pressures of various individuals and organizations. Also, an emergency situation or a situation that evolves into a crisis can have a long-term impact on a country's economy, international relations, reputation, and abroad, etc. This book presents the institutional framework for crisis management in Greece, particularly in the Hellenic Police, Fire Service, Coast Guard, and Civil Protection, as described in the relevant legal provisions up to the time of its publication, while also describing the main characteristics of a crisis, its management, and the decision-making process during a crisis.
