An earthquake results from sudden movement when two blocks of earth slip past one another. It includes tremors & vibrations of the surface of the earth. In a densely populated location, an earthquake may result in damage, loss of property, and fatalities. According to the Maximum Considered Earthquakes, India is divided into four seismic zones namely Zone-II, Zone-III, Zone-IV, and Zone-V) where Zone-V expects the highest level of seismicity and Zone II is considered to be the lowest level of seismicity. 

Seismic ZoneIntensity on the MSK scale
Zone-II (Low Damage Risk Zone) VI or less
Zone-III (Moderate Damage Risk Zone)VII
Zone-IV (High Damage Risk Zone)VIII
Zone-V (Very High Damage Risk Zone) IX or more

The coastal regions of India are worst affected by cyclones every year. Tropical cyclones occur in the months of May-June and October-November. India is geographically divided into six wind zones as follows:

High Damage Risk Zone47
Moderate Damage Risk Zone-A44
Moderate Damage Risk Zone-B39
Low Damage Risk Zone33

We all know that many Indian states are highly prone to floods. 80% of precipitation occurs in the monsoon months from June to September resulting in cloudbursts, floods & urban flash floods in many regions. The flood map of India is available here: for your kind reference.


Landslides/rockfalls/mudflows are various forms of mass wasting where a significant portion of the debris placed on the loose soil moves downwards.  The landslides are often triggered by heavy rainfall, an earthquake, or a manmade slope cut.

Please verify whether your location is prone to landslides using


Thousands of thunderstorms occur in India every year, especially during the monsoon season. A thunderstorm is considered to be a localized storm accompanied by lightning and thunder. These lightning strikes can cause harm to life & property. Please use the thunderstorm incidence map to see the vulnerable locations.
