5.6. Human Mortality and Morbidity
Human mortality and morbidity is one the most devastating impacts of tropical cyclones. Many lives
are lost at the onslaught of the cyclones and many more are being lost in the subsequent phases –
which can be termed as direct and indirect consequences.
The amount of direct death and injury caused inland by high velocity cyclonic winds is mostly
attributable to the temporary nature of human shelter. Loose roof materials fly off and hit as
projectiles due to wind gusts. Uprooted trees and other objects find it easy to damage shelters made
with temporary materials. Therefore, degree of vulnerability of human life is directly correlated to the
degree of Composite Vulnerability (H) of the Housing stock [Refer Section 5.2.].
On the other hand, indirect death and morbidity takes place due to inadequate aid and relief supply
due to poor road connectivity, pathogenic environment, non-existent heath care facilities and lack of
awareness. The incidence of indirect loss is particularly high on certain age groups – especially
children in the 0-10 age cohort and elderly population with age greater than 60. The magnitude of
indirect loss is more aggravated by socio-economic backwardness.
In this study, we have tried to identify the population at risk and estimate the relative degree of
vulnerability based on several parameters. Composite Index of Vulnerability for the housing stock is
used as a proxy of degree of vulnerability to direct human mortality and morbidity (M'). On the
contrary, degree of vulnerability to indirect human mortality and morbidity (M'') is estimated from the
composite index of vulnerability for physical and social infrastructure (I) along with Composite Index
of Socio-economic vulnerability (S) [Refer Section 5.4. and 5.5.].
