What is a one-sentence summary of the following article?
If you are in a wheelchair or otherwise unable to do this, do not worry. Duck your head, and cover your neck to protect it from debris. Stay as low to the ground as possible. Use one arm to cover your neck and head, in case nearby objects fall on you. If possible, hold a pillow or couch cushion over your neck to protect it from debris. Hide underneath a table or desk if you are close to one when the earthquake starts. Use surrounding items such as couch cushions to cover as much of your body as possible, as earthquake movement is unpredictable and can cause many things to fall from the walls or topple over onto the floor. Use one hand to stabilize yourself and prevent yourself from being hurt. If possible, keep close to the ground in a clear space and away from furniture.

Summary:
Drop onto your hands and knees. Protect your head and neck from harm. Cover your body. Hold onto something secure.
