EARTHQUAKE RESISTENT BUILDINGS
IN SEISMIC ZONES OF INDIA
Earthquakes occur due to movements along faults that have evolved through geological and tectonic processes. Often they occur without any prior warning and are, therefore, unpredictable. The large area of India is prone to earthquake. The construction of earthquake resistant building is the only solution for safeguarding our urban centres from the menace of earthquakes.
On the basis of occurrence of earthquakes of different intensities, the National Building Code of India divide the country into five seismic zones as described on the above map. The zone V is the highest risk zone where earthquakes of having intensity of 9 plus on the Richter scale can take place. Earthquake of an intensity between 8 to 9 can be experienced in Zone IV whereas earthquake can occur between 6 and 8 on the Richter scale in Zone III of India.
The respective seismic zones of important urban centres of India are described as below.
