High Resolution 1:10,000 scale Mapping Strategy of Multi ... - NDMA

� Step 6: The maximum intensity or worst case intensity may be chosen to
identify the hazard in that block.
Example 1: An earthquake of magnitude 7+ occurring in the block shown by red star
produces an intensity X in MM scale. The intensities in the neighboring block will be
distributed as shown below. For more details , please refer to Annex- IV.

Figure 5.3 : Intensity distribution for one epicenter
Example 2: In this case two earthquakes of magnitude 7 + occurring in two blocks
at distance of 500 km apart will have different intensity distribution in the common
blocks. The zones are denoted in two colors of blue and brown.
