This document discusses landslides and disaster management. It covers types of disasters including natural disasters like landslides, earthquakes, floods, and man-made disasters. Causes of landslides include geological weaknesses, erosion, rainfall, excavation, and earthquakes. The disaster management cycle includes pre-disaster planning, response during the disaster, and post-disaster recovery. Major landslides in India are described and hazard mapping is discussed as a way to reduce landslide risks and prevent loss of life and property.
Man made disasters are hazards caused by human action or inaction. They are contrasted with natural hazards. Man made disasters may adversely affect humans, other organisms and ecosystems. The frequency and severity of hazards are key elements in some risk analysis methodologies.

The methods of controlling the effects of landslides, and avoiding their menace are also highlighted. Disaster management methods are to be adopted to mitigate the never ending natural hazards. This lesson is an important topic in disaster management.
This presentation is about landslide and i prepared this to know about the knowledge of landslide and how to do during landslide for safe. I hope to see your comments.
Monitoring and Assesment of Landslide from Agastmuni to Sonprayagpaperpublications3
Abstract: The present work is concentrated on the landslides which are very common disaster in the Himalayan region. This specific research theme was attempted taking cues from preparation of a landslide inventory, damage assessment, hazard mapping and subsequently risk analysis. Moreover Landslide change detection of two event pre and post Digitized based on visual interpretation over LISS4 image.
Landslide inventory, a catalogue of present and past landslides prepared by comparing pre and post Kedarnath disaster from a high resolution IRSP6 LISS4 image. Multiple landslides are identified and marked along the Mandakini River course in the inventory map. For susceptibility mapping eight data layers viz Geology, Geomorphology, Slope, Aspect, Distance to lineament, Soil type stream order, NDVI and LULC were created from different sources like SRTM DEM (30M), high resolution multispectral image, soil map etc. Then by weighted overlay in which weights are assigned to each layer according to their influence, susceptibility map is prepared. The statistics of the map indicate that 4% of the area is under high susceptible zone.
After that vulnerability and risk assessment analysis was carried out considering agriculture, built-up and road as important elements. According to the obtained vulnerability map only 7% of the area is under high vulnerability zone where most of the built-up and road is concentrated. The final map is the risk map which shows that only 3% of the total area is under high risk zone.
Keywords: Landslide, Hazard Mapping, Susceptibility Map, Vulnerability Map, Risk Mapping.

Landslide Hazard Management of Darjeeling Hill A Critical Need For Inhabited.inventionjournals
ABSTRACT: Landslides are the most widespread natural disaster in Darjeeling Himalaya which increases its spatial extent day after day. For several natural causes and strong human impact on highly fragile and sensitive hill ecological landscape in form of deforestation, constructions the natural stability are accelerated out. Natural factors like rainstorms, earthquake can trigger landslides. During landslide the materials like soil, rock, vegetation, and existing construction may move very rapidly within a second where as some may take longer time to develop. The result is livelihood security lost, socio-economic condition of people destroys and a huge amount of revenue spent with untold suffer of victims after landslide occurrences. Thus it is required to identify the landslide vulnerable area in advance. To mitigate landslide hazard effectively new methodologies are required to develop. Besides structural measure some recent measure and non structural measure are also essential for better management of landslide prone hilly terrain of Darjeeling district. In the light of the prime objective of the paper is landslide hazard management of Darjeeling hill - a critical need for inhabited the present study evaluating how to minimise the landslide occurrences and its impact.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. LANDSLIDES
The term landslide refers to the downward movement of masses of rock
and soil. Landslides are caused by one or a combination of the following
factors: change in slope gradient, increasing the load the land must bear,
shocks and vibrations, change in water content, ground water movement,
frost action, weathering of shocks, removal or, changing the type of
vegetation covering slopes.
Landslide hazard areas occur where the land has certain characteristics
which contribute to the risk of the downhill movement of material. These
characteristics include:
4. i A slope greater than 15 percent.
ii Landslide activity or movement occurred during the last 10,000
years.
iii Stream or wave activity which has caused erosion, undercut a bank
or cut into a bank to cause the surrounding land to be unstable.
iv The presence or potential for snow avalanches.
v The presence of an alluvial fan which indicates vulnerability to the
flow of debris or sediments.
vi The presence of impermeable soils, such as silt or clay, which are
mixed with granular soils such as sand and gravel.
Landslides can also be triggered by other natural hazards such as rains,
floods, earthquakes, as well as human-made causes, such as grading,
terrain cutting and filling, excessive development, etc. Because the
factors affecting landslides can be geophysical or human-made, they can
occur in developed areas, undeveloped areas, or any area where the
terrain has been altered for roads, houses, utilities, buildings, etc.
5. DISASTER
The term disaster owes its origin to the French word
“Desastre” which is a combination of two words ‘des’
meaning bad and ‘aster’ meaning star. Thus the term
refers to ‘Bad or Evil star’. A disaster can be defined as “A
serious disruption in the functioning of the community or
a society causing wide spread material, economic, social or
environmental losses which exceed the ability of the
affected society to cope using its own resource.
A disaster is a result from the combination of hazard,
vulnerability and insufficient capacity or measures to
reduce the potential chances of risk.
6. A disaster happens when a hazard impacts on the
vulnerable population and causes damage, casualties
and disruption. Fig. would give a better illustration of
what a disaster is. Any hazard – flood, earthquake or
cyclone which is a triggering event along with greater
vulnerability (inadequate access to resources, sick and
old people, lack of awareness etc) would lead to
disaster causing greater loss to life and property. For
example; an earthquake in an uninhabited desert
cannot be considered a disaster, no matter how
strong the intensities produced.

10. Causes of landslides
There are several causes of landslide. Some of the
major causes are as follows:
1. Geological Weak material: Weakness in the
composition and structure of rock or soil may also
cause landslides.
2. Erosion: Erosion of slope toe due to cutting down of
vegetation, construction of roads might increase the
vulnerability of the terrain to slide down.
3. Intense rainfall: Storms that produce intense rainfall
for periods as short as several hours or have a more
moderate intensity lasting several days have triggered
abundant landslides. Heavy melting of snow in the
hilly terrains also results in landslide.
11. 4. Human Excavation of slope and its toe, loading of
slope/toe, draw down in reservoir, mining,
deforestation, irrigation, vibration/blast, Water
leakage from s
5. Earthquake shaking has triggered landslides in
many different topographic and geologic settings.
Rock falls, soil slides and rockslides rom steep slopes
involving relatively thin or shallow dis-aggregated
soils or rock, or both have been the most abundant
types of landslides triggered by historical
earthquakes.
6. Volcanic eruption Deposition of loose volcanic ash
on hillsides commonly is followed by accelerated
erosion and frequent mud or debris flows triggered by
intense rainfall.

13. Disaster management
Is a systematic process (i.e., is based on the key
management principles of planning, organising, and
leading which includes coordinating and Controlling).
Aims to reduce the negative impact or consequences of
adverse events (i.e., disasters cannot always be
prevented, but the adverse effects can be minimised)
14. MAJOR LANDSLIDES:
July 1991 ASSAM 300 people killed heavy loss to
roads and infrastructure
Aug 1993 NAGALAND 500 killed and more than 200 houses
destroyed and about 5 kms road
damaged
18th
Aug 1998 MALPA 210 people killed villages are washed
away
15. Adverse Effects:
The most common elements at risk are the
settlements built on the steep slopes, built at the toe
and those built at the mouth of the streams emerging
from the mountain valley. All those buildings
constructed
without appropriate foundation for a given soil and
in sloppy areas are also at risk.Roads, communication
lines are vulnerable.

21. POST DISASTER STUDIES
The post-disaster studies were governed by the
emerging disaster management scenario. These
include 1) development and updating of inventory
data bases (of existing landslide incidences) on a
continuing basis, 2) quick response to landslide
incidences, 3) preliminary assessment and detailed
studies of existing disastrous or potentially disastrous
landslides posing danger to habitations and 4)
infrastructural elements and other civil projects
22. POST DISASTER STUDIES
The landslides information reporting preformed was
developed for reporting Occurrence landslides to the DMS
Control room GSI New Delhi
Landslide pre study include reconnoiter studies followed y
detailed analysis, preliminary monitoring of a few
landslides and efforts to stabilize the disasters landslides
The preliminary/ reconnoiter studies of specific slides
were carried out – to asses the magnitude, suggest
remedies and identified slides that required detail study
The work carried out included 34 incidents in HP 65 in
Uttarakand, 20 in Jammu Kashmir , 111 in West Bengal , 4
in Guwahati –Assam, 6 in Manipur

28. LANDSLIDES IN INDIA (GSI)
India is vulnerable le to different natural hazards due to
its proximity to geodynamic ally active and unique
climatic pattern.
It is estimated that about 60 % of the landmass of the
country is vulnerable le to earth quakes of different
magnitude, and 15% of the total area of the country is
susceptible to landslides
The severity of natural disaster in our country is indicated
y the estimate of the ministry of home affairs which
indicate in the decade 1990-2000 annually, an average of
4344 people lost their life and 30 million people are
effected y the disaster
29. Possible risk reduction measures:
Hazard mapping locates areas prone to slope
failures. This will help to avoid building settlements
in such areas. These maps will also serve as a tool for
mitigation planning.
30. Land use practices such as:
Areas covered by degraded natural vegetation in upper
slopes are to be afforested with suitable species.
Any developmental activity initiated in the area should be
taken up only after a detailed study of the region has been
carried out.
In construction of roads, irrigation canals etc. proper care is
to be taken to avoid blockage of natural drainage
Total avoidance of settlement in the risk zone should be
made mandatory.
Relocate settlements and infrastructure that fall in the
possible path of the landslide
No construction of buildings in areas beyond a certain
degree of slope
31. Retaining Walls can be built to stop land
from slipping (these walls are commonly
seen along roads in hill stations). These are
constructed to prevent smaller sized and
secondary landslides that often occur along
the toe portion of the larger landslides.

36. CONCLUSION
Landslides are one of the major disaster which effects
15% of the landmass.
It leads to destruction of life and property.
Disaster management of landslides is a very
important step towards reducing the effects of the
event.
Disaster management should be practiced by all
individuals as well as community in pre, post disaster
situations.
