Do not stop on overpasses, underpasses, or bridges, and be aware of overhead hazards such as power lines or falling building debris. In the downtown area it is safer to remain inside the buildings after an earthquake. Unless the building has suffered structural damage or there is a fire, chemical spill, or a gas leak, it is much safer to remain inside. There are no open areas in downtown areas far enough from glass or other falling debris to be considered safe refuge sites. Outside is no place to be in the downtown area during or after an earthquake because of falling objects.
Aftershocks can cause additional damage, and more glass and debris can fall.
