Seismic Zones

There are five seismic zones named as I to V as details given below:-

Zone V: Covers the areas liable to seismic intensity IX and above on Modified Mercalli Intensity Scale. This is the most severe seismic zone and is referred here as Very High Damage Risk Zone.
Zone IV: Gives the area liable to MM VIII. This, zone is second in severity to zone V. This is referred here as High Damage Risk Zone.
Zone III: The associated intensity is MM VII. This is termed here as Moderate Damage Risk Zone.
Zone II: The probable intensity is MM VI. This zone is referred to as Low Damage Risk Zone.
Zone I: Here the maximum intensity is estimated as MM V or less. This zone is termed here as Very Low Damage Risk Zone.

The Maximum Intensity on Modified Mercalli Scale considered for the Five Zones are

MSK IX or more in Zone V
MSK VIII in Zone IV
MSK VII in Zone III
MSK VI in Zone II.

In the revision of the seismic zones in year 2000, the seismic Zone I has been merged in Zone II by BIS Seismic Zoning Committee, hence there are now four zones only number II, III, IV & V.
