Microzonation Maps

What are microzonation maps?

  • Effects of earthquake shaking are not uniform due to variation in local site conditions.
  • Seismic microzonation maps display predicted variation in earthquake shaking (site effects) due to local site conditions.
  • The input data to produce these maps includes geological, geophysical, geotechnical information combined with numerical modelling.
