How to build Earthquake Resistant Buildings in India

The devastating earthquake in Nepal has reignited the debate about earthquake safety in buildings across India, and how they can be made safer. Here is the list of some top earthquake-proofing technologies in the world.

1. Base Isolation System

The actual structure of the building is separated from the foundation. They have rubber bearings and a sliding seismic isolator between them so that during a shake, the foundation slides but the building doesn't. This cuts down the intensity of the shake, keeping the structure

What kinds of buildings use it?

Buildings across the globe that provide critical services such as hospitals, telecommunication links and others, which are usually lower in height, utilize base isolation systems.


Dampers are like large shock absorbers used in cars, helping dissipate the energy generated during an earthquake thereby keeping the larger structure on top safe

What kinds of buildings use it?

High-rise buildings use different kinds of dampers. Dampers can also be used to retrofit older buildings that might not have been designed as earthquake resistant structures

3. Levitation

The house is levitated off the ground when an earthquake strikes. The house stands on a deflated air bag during normal times. When the earth shakes, a compressor pumps air into the bag which lifts the house a few centimeters off the ground, so that the impact is not felt on the structure

What kinds of buildings use it?

- Stand-alone houses

Types Of Earthquake Resistant Buildings

Fully operational

The building, its occupants, utilities and its contents might get shaken by an earthquake but there is no damage to any of them. The functioning of the building is not disrupted

Immediate occupancy

The contents and utilities of the building are shaken and might suffer some minor damage, but it does not stop the building from being used right after the earthquake

Life safety

The building, its occupants and contents are severely shaken. This can cause significant damage, but the structure does not reach a state of imminent collapse. The building will not be usable until a structural safety assessment is done to see if it can be retrofitted.

Collapse prevention

The building and all its utilities, contents and occupants are severely shaken and major damage is likely to occur to each of them. This building will not be usable by its occupants after the earthquake and will be in a state of imminent collapse.
