Stress builds up and the rocks slips suddenly, releasing energy in waves that travel through the earth’s crust and cause the shaking. A number of significant earthquakes occurred in and around India over the past century.

Geography of India and The World

Earthquake in Nepal and Northern India Live News Updates These studies involving preparation of geological, geomorphological and land use maps followed by drilling, geological logging, standard penetration test and geophysical studies to demarcate the zones of least to most damage prone areas within the urban areas helps the respective town and country planning agencies to formulate perspective planning within the overall earthquake impact minimization efforts.

Views Read Edit View history. II Downloda intensity downlod. In Bihar the northern part of the state like RaxaulNear the border of India and Nepal, is also in zone no The Indian subcontinent has a history of devastating earthquakes. Mumbai comes in Zone 3.

The Modified Mercalli MM intensity, which measures the impact of the earthquakes on the surface of the earth, broadly associated with various zones, is as follows: The specifications given in the design code IS The zone factor of 0. The Modified Mercalli MM intensity, which measures the impact of the earthquakes on the surface pddf the earth, broadly associated with various zones, is as follows: To Subscribe Newsletter and Get Updates.

Archived from the original on This plate is colliding against the huge Eurasian Plate and going under the Eurasian Plate; this process of one tectonic plate getting under another is responsible for making India a earthquake prone country.

In other words, the earthquake zoning map of India divides India into 4 seismic zones Zone 2, 3, 4 and 5 unlike its previous version, which consisted of five or six zones for the country.

National Zonfs for Seismology, Ministry of Earth Sciences is nodal agency of Government of India dealing with various activities in the field of seismology and allied disciplines. According to the present zoning map, Zone 5 expects the highest level of seismicity whereas Zone 2 is associated with the lowest level of seismicity. Of these, Zone V is the most seismically active region, while zone II is the least.

V Very severe intensity zone. Zone-II covers remaining parts downpoad the country. Seismic Zone Intensity on MM scale: This page was last edited on 27 Februaryxeismic By using this site, you agree to the Terms of Use and Privacy Policy. In Maharashtrathe Patan area Koynanagar is also in zone no Study Material Test Series.

An earthquake is caused by a sudden slip on a fault. Bureau of Indian Standards, based on the past seismic history, grouped the country into four seismic zones, viz. IV Severe intensity zone.

Since the current division of India into earthquake hazard zones does not use Zone 1, no area of India is classed as Zone 1. The Modified Mercalli MM intensity, which measures the impact of the earthquakes on the surface of the earth, broadly associated with various zones, is as follows:.

Bureau of Indian Standards, based on the past seismic history, grouped the country into four seismic zones, viz. Give a Miss Call: These studies involving preparation of geological, geomorphological and land use maps followed by drilling, geological logging, standard penetration test and geophysical studies to demarcate the zones of least to most damage prone areas within the urban areas helps the respective town and country planning agencies to formulate perspective planning within the overall earthquake impact minimization efforts.

Intensity on MMI scale. Stresses in the earth’s outer layer push the sides of the fault together.

From Wikipedia, the free encyclopedia. Each zone indicates the effects of an earthquake at a particular place based on the observations of the affected areas and can also be described using a descriptive scale like Modified Mercalli intensity scale [4] or the Medvedev—Sponheuer—Karnik scale.

Thus, a seismic zone map is required to identify these regions. Retrieved from ” https: The IS code assigns zone factor pdd 0. Of these, Zone Downloa is the most seismically active region, while zone II is the least. Zone 5 covers the areas with the highest risks zone that suffers earthquakes of intensity MSK IX or greater.

An Earthquake occurs when plates grind and scrape against each other. III Moderate intensity zone. A World Bank and United Nations report shows estimates that around million city dwellers in India will be exposed to storms and earthquakes by India lies at the northwestern end of the IndoAustralian Plate, which encompasses India, Australia, a major portion of the Indian Ocean and other smaller countries.

Zone-II covers remaining parts of the country. Some of these occurred in populated and urbanized areas and hence caused great damage. Structural designers use this factor for earthquake resistant design of structures in Zone 5. The IS code follows a dual seisic philosophy: The Times Of India. Instead, each zone factor represents the effective period peak ground accelerations that may be generated during the maximum considered earthquake ground motion in that zone.

Generally, the areas having trap rock or basaltic rock are prone to earthquakes.
