Is It Safe to Take Shelter in Stairs During an Earthquake?

During an earthquake, taking shelter in stairs has long been considered an unsafe option. This article explores the reasons behind this recommendation and discusses alternatives that can keep you safer during seismic activity.

Key Reasons Why Stairs Are Not Safe During an Earthquake

The differential movement, vulnerability to collapse, injury risks, and crowding concerns associated with using stairs during an earthquake highlight why this location is not recommended for safety.

Differential Movement

Staircases often have a different vibration pattern compared to the main structural elements of a building. During an earthquake, the building and the stairs may move independently, leading to potential collisions and structural failure. This phenomenon is known as differential movement.

Vulnerability to Collapse

Staircases are typically designed to support vertical loads, but they may not be reinforced to withstand lateral forces generated during an earthquake. In severe shaking, the stairs can fail, leading to dangerous situations for anyone using them.

Injury Risks

If stairs do collapse, individuals on them can suffer severe injuries. The movement of the stairs can cause people to be caught or crushed, leading to serious injuries.

Crowding Concerns

In the event of an earthquake, many people may rush to the stairs to evacuate, overloading them and increasing the risk of collapse even if they appear stable initially.

Recommended Safety Actions During an Earthquake

There are several recommended actions to take during an earthquake to ensure your safety:

Stay Indoors

The safest location during an earthquake is usually indoors. Avoid trying to exit the building via stairs, as most injuries occur when people try to move during the shaking.

Drop, Cover, and Hold On

Follow the Drop, Cover, and Hold On protocol. Seek cover under sturdy furniture such as a table or desk and hold on until the shaking stops.

Stay Away from Windows, Glass, and Heavy Furniture

Remain in one place and move away from windows, glass, and heavy furniture that could fall during the earthquake.

Move to an Open Area if Outside

If you are outside, move to an open area away from buildings, trees, streetlights, and utility wires.

Stay in Your Vehicle if Driving

If you are driving, pull over to a safe location, stop, and stay in the vehicle until the shaking stops.

Conclusion

While taking shelter in stairs during an earthquake can seem like a safe option, it is important to understand the risks involved. The recommended safety actions are designed to minimize the chances of injury or worse. Always follow local guidelines and building codes to ensure earthquake preparedness and safety.
