When seismic waves tear through the earth, hospitals and schools are often the places that capture the public’s attention most deeply. These two types of public buildings, which bear the burden of saving lives and holding the hope for the future, have seismic resilience that matters not only for the survival of the structures themselves but also directly affects the safety of countless vulnerable lives. Therefore, fortifying the seismic defenses of hospitals and schools is by no means a simple matter of structural reinforcement; rather, it is a core issue concerning social resilience and moral responsibility.
Traditional seismic design approaches have largely focused on ensuring that buildings “do not collapse,” thereby buying time for people to evacuate. However, for hospitals and schools, this standard is far from sufficient. After an earthquake, hospitals must immediately transform into disaster relief hubs, ensuring that critical medical functions remain uninterrupted; schools, meanwhile, must serve as reliable shelters and safe havens, ensuring the safety of students and staff while maintaining basic order. This requires that our seismic strategies evolve from “saving lives” to “preserving functionality,” achieving a leap from “earthquake resistance” to “resilience.”
Achieving this leap hinges primarily on precise “diagnosis” and tailored “prescriptions.” Every building has its unique history, structure, and functional layout. For hospitals, the focus must be on assessing seismic vulnerabilities in operating rooms, intensive care units, emergency access routes, pharmaceutical storage areas, and critical life-support systems such as electricity, oxygen, and water supply. For schools, attention must be paid to classroom walls, corridor connectivity, the structural safety of large spaces such as gymnasiums, and the usability of open spaces like playgrounds as emergency evacuation areas. Only by identifying the most critical hazards through professional seismic testing and assessment can we avoid “one-size-fits-all” reinforcement and allocate limited resources to the most critical areas.
In terms of specific technical approaches, we have a diverse “toolkit” at our disposal. For new construction, higher seismic design standards should be adopted directly, and new technologies such as base isolation and vibration damping should be actively applied. For example, installing base isolation bearings at the building’s foundation or between floors is akin to putting “skates” on the building; this effectively isolates and dissipates seismic energy, ensuring the stability of the superstructure. For the vast number of existing buildings, scientific seismic retrofitting is required. This includes using materials such as carbon fiber fabric and steel plates to reinforce the strength of walls, beams, and columns; adding steel bracing or shear walls to enhance overall stability; or securely anchoring unstable non-structural components (such as suspended ceilings, light fixtures, and large equipment) to prevent secondary damage.
However, even the sturdiest buildings require a “combination of hard and soft measures.” Comprehensive earthquake emergency response plans and routine drills serve as the “software system” that activates a building’s seismic resilience. Hospitals should establish detailed earthquake emergency procedures covering every aspect—from patient evacuation and surgical procedure interruption protocols to emergency power switching and resource allocation—and ensure that every member of the medical staff clearly understands their responsibilities. Schools, meanwhile, need to regularly organize earthquake evacuation drills for students and staff, integrate safety knowledge into daily education, and clearly define post-earthquake assembly procedures, headcounts, psychological support, and potential community shelter functions. These non-engineering measures ensure that, in the chaos of an earthquake, sturdy buildings can deliver maximum protective effectiveness.
Furthermore, community coordination and the pre-positioning of resources are equally indispensable. Hospitals and schools should not operate as isolated entities in earthquake preparedness. In terms of planning, roads surrounding hospitals should be kept clear to facilitate the movement of rescue teams and the transport of injured patients; schools, meanwhile, should establish coordination mechanisms with the communities they serve to share emergency supplies and information. Within the buildings themselves, strategically stockpiling emergency water, food, medicine, lighting, and communication equipment can support core operations for a period of time even under extreme conditions of water and power outages.
Strengthening the earthquake-resilience defenses of hospitals and schools is an ongoing, systematic endeavor. It requires the government to raise seismic design standards and strengthen oversight; it requires building owners to fulfill their primary safety responsibilities; it requires engineers to continuously innovate and apply appropriate technologies; and it requires every user to possess risk awareness and the ability to self-rescue and assist others. When seismic waves are inevitable, all we can do is make a 100% effort in advance to mitigate that uncertain 1% risk. Ensuring that hospitals can continue to illuminate the light of life amidst disaster, and that schools can continue to safeguard children’s smiles amidst turmoil, is not only the goal of engineering and technology but also society’s most solemn commitment to life and the future.
