Give scientific reasons.
It is safer to find shelter under things like a bed, table at the time of earthquake.
In an earthquake, most of the injuries occur because of falling or toppling over of heavy things from above. Furnitures like bed, table will protect you from these things falling from above. Also, it becomes very difficult to maintain one’s balance in a quake. The crouched position under these furnitures will reduce the chances of a fall.
If there is complete structural collapse, it is hoped that these furnitures increase the likelihood of a safe pocket from which you can be rescued.
