Gurgaon falls under the high-risk Seismic zone IV making it susceptible to earthquakes CONSTRUCTION OF
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.

    An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The sides of a fault move past each other smoothly…

    Thesis: Earthquakes have been a natural part of Earth for many years and are caused by a shift in the Earth’s tectonic plates. Tectonic plates shift when two separated pieces of Earth’s crust push together because of the pressure of the hot air below them pushing up on the plates from the heat of the Earth’s core. This pressure must be released somehow, so when the pressure becomes too great for the plates to withstand, one part of a plate gives way to the pressure by rising above the other part…
