2. DISASTER MANAGEMENT
A DISASTER IS A SUDDEN, CALAMITOUS EVENT THAT SERIOUSLY
DISRUPTS THE FUNCTIONING OF A COMMUNITY OR SOCIETY AND
CAUSES HUMAN, MATERIAL, AND ECONOMIC OR ENVIRONMENTAL
LOSSES THAT EXCEED THE COMMUNITY'S OR SOCIETY'S ABILITY TO
COPE USING ITS OWN RESOURCES. THOUGH OFTEN CAUSED BY
NATURE, DISASTERS CAN HAVE HUMAN ORIGINS.

3. AIM OF DISASTER MANAGEMENT
• DISASTER MANAGEMENT AIMS TO REDUCE OR AVOID, THE
POTENTIAL LOSSES FROM HAZARDS, ASSURE PROMPT AND
APPROPRIATE ASSISTANCE TO VICTIMS OF DISASTER AND ACHIEVE
RAPID AND EFFECTIVE RECOVERY.

14. WHAT IS PARADIGM SHIFT ?

15. PARADIGM SHIFT:-
A fundamental change in approach or underlying assum

20. The Government of India has shifted its approach to disaster management
from old traditional Disaster Management to new sustainable approach is
termed as ‘PARADIGM SHIFT’

26. RISK ASSESSMENT OR ANALYSIS AND
MAPING

27. Disaster risk Assessment or analysis
A disaster Risk Analysis is a comparative analysis of the nature and extent of risks
linked to different kinds of hazards and vulnerable condition that could harm people,
assets, livelihoods, infrastructure and services in a given locality. common results of
risk assessment are hazard and risk maps, risk matrices that compare and rank risks
from different hazard scenarios and prioritized action-plans for DRR.

2.DETERMINING THE SCALE AND OBJECTIVE OR ANALYSES

31. IDENTIFYING POTENTIAL IMPACT AND VULNERABILITY
• Hazard analysis has established the intensity, duration, location and likelihood of
damaging hazard events that may occur in the area.
• Vulnerability depends on physical, social, economic and environment attributes and
the presence or absence of certain capacities to avoid or withstand, cope and recover
from a hazard.

33. Vulnerability and Risk Mapping :-
Earlier we have already briefly looked at hazard and exposure maps. By adding
spatial information on vulnerability to hazard information we can identify high-
risk areas In order to establish these maps we use data on likelihood and impact
that can be spatially referenced.

34. EVALUATING AND ACTING UPON RISK ANALYSIS RESULTS
 Risk analysis is not an end in itself but performed as an essential component
of preparedness efforts.
 Ultimately risk analysis should result in plan and action. There are two main
options once a disaster risk analysis is completed :
 Integrate disaster risk reduction n issues and practices into local government
plans and programmer.

35. SEISMIC MICROZONATION
PRINCIPLE AND METHODOLOGY

36. SEISMIC ZONING AND SEISMIC MICROZONATION
SEISMIC ZONING
Seismic zoning consists of subdividing a national
territory into several several zones indicating
progreessive levels of expected seismic intensity of
ground motion

37. SEISMIC MICROZONATION
-SEISMIC MICRO ZONATION IS DEFINED AS THE PROCESS
OF SUBDIVIDING A POTENTIAL SEISMIC OR EARTHQUAKE
PRONE AREA INTO ZONES WITH RESPECT TO SOME
GEOLOGICAL AND GEOPHYSICAL CHARACTERISTICS OF
THE
SITES SUCH AS GROUND SHAKING , LANDSLIDE AND ROCK
FALL HAZARD ,EARTHQUAKE-RELATED FLOODING , SO
THAT
SEISMIC HAZARDS AT DIFFERENT LOCATION WITHIN THE
AREA CAN CORRECTLY BE IDENTIFIED

39. METHODS OF SEISMIC MICROZONATION
Dynamic characteristics of site such as predominant period,
amplification factor, shear wave velocity, standard penetration test
values can be used for seismic micro zonation purpose. Shear
wave velocity measurement and standard penetration test are
generally expensive and are not feasible to be carried out at large
number of sites for the purpose of micro zonation. Ambient
Vibrations measurement (also called Micro tremor) has become a
popular method for determining the dynamic properties of soil
strata and is being extensively used for micro zonation. Micro
tremor observations are easy to perform, inexpensive and can be
applied to places with low seismicity as well, hence, micro tremor
measurements can be used conveniently

40. PRINCIPLE OF SEISMIC MICROZONATION
A ground motion prediction is important key
to assess and mitigate the earthquake
hazard .
There are some factors by which level of
strong ground motion is controlled .
The main factors are source , site conditions ,
and path.
Among these site condition played an
important role on damage to structures as
seen from previous bhuj earthquake and
mexico earthquake.
For this purpose methods of characteriszing
site effect is required keenly.
It is also required for the study of soil
behaviour.
During strong ground shaking as it has been
noticed from many past earthquake ,the

43. NEED FOR SEISMIC MICROZONATION
Seismic micro zonation is the first step
in earthquake risk mitigation study and
requires multidisciplinary approach
with major contributions from the
fields of geology , seismology ,
geophysics Geotechnical , and
structural engineering.
This is very important to identify the
tectonic and geological formations in
the study area which is essential for
determining the seismic sources and
also for establishing a realistic
earthquake hazard models for the
investigation .

44. MICROZONATION EXPERIMENT IN INDIA
SEISMIC MICROZONATION OF DELHI
-MICRO ZONATION OF DELHI HAS BEEN CARRIED OUT BY
A GROUP OF MEMBERS FROM DIFFERENT INSTITUTIONS.
-SCALE FOR THIS MICRO ZONATION MAP INCLUDE GEOLOGY-
GY ,BASE MAP ,SEISMIC HAZARD MAP ,PEAK GROUND
ACCELERATION ,SHEAR WAVE VELOCITY.
-THE AREA FOR THIS STUDY HAS BEEN GROUPED INTO
THREE HAZARD ZONES I.E. LOW MODERATE ,HIGH.
-PEAK GROUND ACCELERATION MAP AT BEDROCK LEVEL FOR
FIVE DIFFERENT SOURCES IN DELHI WAS CARRIED OUT BY RAO AND
NEELY SAT YAM (2005) BY USING COMPUTER CODE FINSIM.

46. SEISMIC MICROZONATION OF GUWAHATI
The first level micro zonation map of Guwahati
Was prepared by Baranwal (2005) .
-This map was based on shape and constituents
Of overburden material inferred from geophysical surveys,
slope of exposed rocks, ground moti-
On amplification-On the basis of susceptibility to amplification
they
Categorized soil profiles

47. • Seismic microzonation involves a very detailed field investigation
to evaluate the hazard.
• It is very effective in delineating the spatial varitions in the
seismic hazard.
• There are also useful to evaluate the risk scenarios in the study
area.
• seismic microzonation maps are very useful in urban planning
because they help to predict the impact of future earthquake and
can also be used to locate key facilities like hospital ,fire station
etc .
