    Vertical and horizontal evacuation are strategies for providing safety to humans in case of tsunami, hurricane or other natural disaster.

    In areas where horizontal evacuation to higher ground is impossible, vertical evacuation to higher areas of a structure may be a way to shelter individuals from the surge of water, several meters high, that can follow an earthquake in coastal areas.

    In the United States

    The U.S. Federal Emergency Management Agency published design guidelines for vertical evacuation structures in 2008. According to the American Society of Mechanical Engineers, serious discussions about vertical evacuation began in the United States following the 2011 Tōhoku earthquake and tsunami. The American Society of Civil Engineers adopted an updated edition of its building standards in September 2016, including tsunami hazards for the first time.

    The first vertical evacuation site in the United States was Ocosta Elementary School, constructed in 2015–2016 on the Pacific Ocean coast in Westport, Washington, where a Cascadia subduction zone magnitude 9+ earthquake is expected to cause great tsunamis.

    Horizontal evacuation

    An alternative to vertical evacuation is horizontal evacuation, for instance a hurricane evacuation route. Critics of vertical evacuation planning have charged it with justifying even greater human density in areas prone to disaster, and prefer low density growth with horizontal evacuation planning.
