An earthquake is the shaking of the surface of Earth due to the sudden release of energy in the Earth’s crust, as a result, seismic waves are created. The seismic activities in an area determine the type and intensity of the earthquake. Some of the measures to be undertaken before and after the earthquake are given below.

Before the Earthquake:

  • Wall hangings and plants must be placed far away from windows and plants must be hanged in lightweight pots with closed hooks, such that they are well secured to the studs.
  • Connections of gas lines and appliances must be made flexible.
  • Heavy and unstable appliances and items must be placed away from doors and exit routes.
  • An earthquake readiness plan must be kept ready, including locating a shelter house, canned food and up to date first aid kit, gallons of water, dust masks, goggles, firefighting equipment, a torch and a working battery operated radio.
  • Architects and structural engineers must be consulted before laying the foundation of buildings in earthquake-prone areas, also the building must be manufactured as per the rules and regulations laid by the disaster management committee.
  • Members of the family must be trained to locate a spot in each room of the house where nothing is likely to fall in the case of calamity.
  • In highly seismic areas, mud and timber are used instead of heavy construction material. The roofs are kept light; the shelves are fixed to the walls so that they do not fall easily.
  • Awareness must be spread among friends and family members about the above-mentioned measures.

The previous steps focused on the preparedness for an earthquake. In the next section, we shall learn about the measures that can be undertaken during the calamity.
