Thanks to those who responded to my earlier mail on hazard scales. I did
follow up the links and found some useful information. However, I am still
stuck for want of `hazard' scales rather than disaster scales.
Basing hazard scales on deaths or damage caused does not really help. A
larger earthquake may kill less people and cause lesser damage than a
smaller one simply because it occurred in a less densely populated area. We
can still be sure that it was a bigger quake from its Richter scale
reading. The same applies for cyclones (SS scale). However, if out of two
landslides, the smaller one causes more deaths/damage, how can one
substantially record that the other one was actually larger? Same too for
droughts, though there do exist some basic practices of terming droughts as
low/med/high on severity based on percentage of normal rainfall over
specified period of time.
any further ideas....??
