Question

mitigation measures for earthquake

Answer 1

The structure of a building or its skeleton, are subject to shearing, bending, torsion, tension and compression during an earthquake. Buildings are designed primarily to resist vertical forces from gravity. The floor and support beams carry these forces down to the support beams which in turn carry them to the foundation and support soil. The failure of this during an earthquake can lead to damage or even total building collapse. Buildings made of  steel and supported concrete tend to withstand earthquake better. Another important building  concept is weight distribution. Buildings that are wide and low to the ground fare better then tall, top heavy buildings such as sky scrapers. It is also important that building materials have a level of redundancy. This insures that even if a few localized elements of the building structure fail that it doesn’t result in total collapse.
Even if your home is secure against earthquakes, it is important that you also take extra measures to protect yourself during an earthquake. The first thing you should do is drop down onto all fours. This prevents you from falling over but allows you to remain mobile. Next, you should protect your head and  body from falling objects by crawling under a sturdy table or desk. Most importantly, hold on! Hold on to your head and neck until the shaking stops. However, you should be prepared to move about in case shaking shifts your structure about.
