Evacuation
Overview
Evacuation refers to the act of leaving a dangerous area and moving to a safe place to minimize casualties during various disasters or emergencies such as fires, earthquakes, floods, typhoons, wars, and terrorist attacks. Evacuation is not only crucial for individual survival but also the most basic and important step in society's overall disaster response system, requiring advance preparation, swift judgment, and orderly movement. The success of an evacuation largely depends on prior education, training, and the proper securing of evacuation routes and shelters.

Types of Evacuation
Evacuation is divided into several types depending on the situation and scale. Vertical evacuation involves moving upward to higher floors or rooftops of buildings during earthquakes or tsunamis, while horizontal evacuation involves moving outside a building or to a safe area on the same level during fires or hazardous material leaks. Additionally, preventive evacuation is carried out in advance when a disaster is anticipated (e.g., evacuating low-lying residents before a typhoon), and emergency evacuation refers to evacuation immediately after a disaster occurs. By scale, evacuation can be classified into individual, family, community, and national evacuations.
Evacuation Procedures and Methods
Effective evacuation requires familiarity with standard procedures. Generally, the steps are: 1) Situation awareness – recognizing the danger through alarms or emergency broadcasts; 2) Judgment – assessing the type and scale of the danger and available evacuation time; 3) Action – moving quickly along pre-learned evacuation routes; and 4) Assembly – arriving at designated shelters or safe points to check in. During evacuation, elevators must be avoided and stairs used; belongings should be minimized (survival kit, medicine, important documents, etc.), and helping those around you is important. The principle of prioritizing vulnerable groups such as children, the elderly, and people with disabilities is emphasized.
Shelters and Evacuation Routes
Shelters are places that provide temporary safety during a disaster, typically designated at schools, gymnasiums, and public buildings. Local governments designate shelters by disaster type, inspect them regularly, and publicize their locations to residents. Evacuation routes are safe passageways from dangerous areas to shelters, and it is advisable to familiarize oneself with multiple routes in advance. Recently, systems providing real-time evacuation routes and shelter information via smartphone apps or disaster text messages have been introduced.
Evacuation Drills and Education
Regular drills are essential to increase the success rate of evacuations. Schools, workplaces, and public institutions conduct fire drills and earthquake evacuation drills quarterly or semi-annually. These drills simulate real situations, covering the entire process from alarm activation and evacuation guidance to moving to shelters and checking in. Additional training such as CPR, first aid, and gas mask use may also be provided. Internationally, some countries designate an 'Evacuation Day' for large-scale drills.
Precautions During Evacuation
The following precautions must be observed during evacuation: First, stay calm and do not panic. Second, do not run; walk quickly to prevent falls. Third, if there is smoke or toxic gas, lower your body and cover your mouth and nose with a wet towel. Fourth, never re-enter a building after evacuating. Fifth, do not move to arbitrary locations instead of designated shelters. Sixth, do not risk danger to save pets or valuable items.
Latest Trends
As of 2024-2025, evacuation systems are accelerating their integration with digital technology. Real-time disaster detection and evacuation route optimization systems using artificial intelligence (AI) have been commercialized, analyzing sensor data in buildings during earthquakes to guide the safest routes via smartphones. Additionally, aerial evacuation guidance and rescue operations using drones have become active, especially in wildfires or flood areas where drones provide voice guidance for evacuation routes. With the increasing frequency of extreme weather events (super typhoons, wildfires, floods) due to climate change, governments are refining evacuation plans. For example, Japan has expanded vertical evacuation facilities for tsunamis, and the U.S. has strengthened laws mandating evacuation drills before hurricane season. In South Korea, from 2024, 'disaster preparedness evacuation drills' have been expanded from twice to four times a year, and digital evacuation maps (electronic map-based shelter information) have been distributed nationwide. Furthermore, evacuation training simulators using metaverse and virtual reality (VR) technology have been developed, enabling effective training without experiencing actual danger. Since the COVID-19 pandemic, quarantine standards (social distancing, ventilation, mask-wearing) for preventing infectious diseases in shelters have been included in evacuation plans.
