Is It Advisable to Stand in a Doorframe During an Earthquake?

Earthquake Dynamics and Structural Weakness

Standing in a doorframe is often touted as a safe place to be during an earthquake, but this advice is based on outdated notions of earthquake physics. In reality, doorframes are not designed to withstand the intense forces generated by seismic waves. A typical doorframe is anchored to the surrounding structure with screws or nails, which can easily fail under the pressure of an earthquake. In fact, studies have shown that doorframes are more likely to be pulled out of the surrounding walls than to provide a safe haven.

Doorframe Instability and Hazards

The instability of doorframes during an earthquake can lead to a range of hazards, including falls, injuries, and even fatalities. If the doorframe collapses, it can crush anyone standing nearby, and the surrounding debris can cause further harm. Moreover, if the doorframe is not securely anchored, it can swing violently back and forth, causing injuries from flying debris or being struck by the doorframe itself.

Safer Alternatives and Precautions

If you find yourself in a room during an earthquake, it’s generally safer to stand near an interior wall, away from windows, doors, and any heavy furniture or equipment. This can help you avoid falling debris and collapsing structures. In areas prone to earthquakes, it’s also essential to secure heavy objects, such as bookshelves and televisions, to walls using earthquake-resistant brackets. Finally, always stay informed about earthquake safety and take steps to prepare for earthquakes, including practicing “drop, cover, and hold on” drills and having a family emergency plan in place.
