why do elevators get stuck during earthquakes?
In: 9
Safety.
An elevator that loses power or has an incident actually fails safe. Literally what the term fail safe means.
Most modern and safe ones will spend energy holding the brakes *off* opposed to having to use power to turn the brakes on.
A stopped elevator with brakes on is less likely to move than trying to run something up and down a tube with a complex system of pullers during an earthquake.
So stopping at a floor is the better than getting possibly stuck somewhere between, or catastrophically failing.
