Podcast 2, Can earthquake microzonation be done for my land?

In the second podcast of NepaliEngineer we discuss the possibility of seismic microzonation. The question was to prepare a map so that a person can know the seismicity of the place while purchasing or building a structure. We discuss the possibility of having such a map by the government. In the course of the preparation for the podcast, I had collected various hazard maps and concluded:

  • although the hazard maps are good for research purpose, they don’t serve as a guideline when making land purchases for residential purpose.
  • there is no consistency between different hazard maps prepared by different authorities (see the papers below).
  • these maps can not be reliable during earthquake.

In the podcast, I discuss about the difficulty in producing a reliable earthquake hazard map useful for land use management.

Some other documentations I found in a quick search include:
