What are the earthquake zones?
Based on the past seismic history, Bureau of Indian Standards grouped the country into four seismic zones namely Zone-II, Zone-III, Zone-IV and Zone-V. Of all these four zones, Zone-V is the most seismic active region whereas Zone-II is the least.
What Does earthquake Zone 1 mean?
Zone 1. Since the current division of India into earthquake hazard zones does not use Zone 1, no area of India is classed as Zone 1.
What are the 3 major earthquake zones?
The global distribution of earthquakes mainly occurs in three types of belt, i.e., Circum-Pacific seismic belt (“Ring of Fire”), Alpide belt, and the Oceanic ridge seismic belt.
Which seismic zone is Kerala in?
seismic zone III
The Kerala state, part of Stable Continental Region (SCR) lies in seismic zone III , where the maximum expected MM scale intensity would correspond to VIII (M ~5.5).

What is the safest distance from a fault line?
But first, what is considered a safe distance from a fault line? PhiVolcs recommends avoiding construction within five meters on each side of a fault trace. This is equivalent to a total width of 10 meters. This is considered the ideal “10-meter wide no-build zone” in the vicinity of a fault.
What is the earthquake risk zone?
What is a seismic zone, or seismic hazard zone? A seismic zone is used to describe an area where earthquakes tend to focus; for example, the New Madrid Seismic Zone in the Central United States.
Is Kerala prone to earthquakes?
KOCHI: Kerala continues to be the most earthquake-free zone compared to other southern states — Tamil Nadu, Andhra Pradesh and Karnataka. This is despite the fact that the recent intense rainfall, quarrying and unscientific construction activities have increased the risk of induced earthquakes in the state.
Which is the largest earthquake in Kerala?
As Kerala is not known to be a high-seismicity zone, an earthquake of magnitude 4.3 that occurred near Wadakkancherri in Thrissur district in 1994 has confounded scientists and caused much alarm among residents.
Is Kerala safe from earthquake?
Where are the earthquake zones located in India?
Regions that fall under the Earthquake (seismic) Zones in India Zone-V covers entire northeastern India, some parts of Jammu and Kashmir, some parts of Ladakh, Himachal Pradesh, Uttarakhand, Rann of Kutch in Gujarat, some parts of North Bihar and Andaman & Nicobar Islands.
Where was the epicentre of the 2000 earthquake in Kerala?

Where are the seismic fault lines in Kerala?
Seismic activity in the recent past has occurred in clusters ( 3) along the border with Tamil Nadu, primarily in the districts of Idukki and Pallakad. A number of faults have been identified in Kerala out of which a few, like the Periyar Fault are active.
Which is the most seismically active region in India?
The Bureau of Indian Standards has classified regions in India into four seismic zones on the basis of historical seismic activity. These are zones II, III, IV and V. Among these, Zone V is the most seismically active region and zone II is the least active.
