Answer: While considering the nature and scope of a disaster, the following phases must be thought over (any four):
- Pre-disaster phase — preparedness and planning before the disaster, to reduce its effects.
- Warning phase — giving warning to people about the possible disaster and shifting them to safe places.
- Emergency phase — search and rescue, first aid and medical help immediately after the disaster, when maximum lives can be saved.
- Rehabilitation phase — providing shelter, food and means of livelihood to the victims.
(The other phases are the recovery phase and the reconstruction phase — rebuilding houses, roads and water supply.)
