Earthquake Zones in India

Earthquake zones are categorized into seismic hazard zones based on the likelihood and intensity of earthquakes in a region. These zones vary by country, but a general classification is:

Seismic Zone Classification

  1. Zone 1 (Very Low Hazard)
    • Least earthquake-prone areas.
    • Rare and weak seismic activity.
    • Example: Parts of central and eastern Canada, some interior regions of Africa.
  2. Zone 2 (Low Hazard)
    • Minor earthquake activity.
    • Occasional moderate tremors, but rarely damaging.
    • Example: Parts of the Midwest USA, parts of Europe.
  3. Zone 3 (Moderate Hazard)
    • Moderate seismic activity.
    • Can experience occasional damaging earthquakes.
    • Example: New Madrid Seismic Zone (USA), parts of Australia.
  4. Zone 4 (High Hazard)
    • Frequent and strong earthquakes.
    • Significant damage potential.
    • Example: California (USA), Turkey, Northern India.
  5. Zone 5 (Very High Hazard)
    • Most seismically active regions.
    • Major fault lines, high earthquake frequency.
    • Example: Japan, Indonesia, the Himalayas, Chile.

Different countries use their own classifications based on regional seismicity and building codes. Would you like details on a specific country’s zoning system?
