This document discusses environmental disasters, including both natural and man-made types. It provides examples of various natural disasters like earthquakes, volcanic eruptions, cyclones, floods, droughts and others. It also discusses man-made disasters such as nuclear disasters, chemical disasters, biological disasters, fire accidents, travel accidents, and terrorism. For each type of disaster, it outlines precautions people can take to protect themselves and mitigate damage.
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.

A natural disaster is the effect of earths natural hazards, for example flood, tornado, hurricane, volcanic eruption, earthquake, heatwave, or landslide. They can lead to financial, environmental or human losses. The resulting loss depends on the vulnerability of the affected population to resist the hazard, also called their resilience. If these disasters continue it would be a great danger for the earth

Introduction to natural hazard and disaster management Jahangir Alam
The earth indeed a hazardous planet
There are 516 active volcanoes with an eruption every 15 days (on average)
Global monitors record approximately 2000 earth tremors everyday
There are approximately 2 earthquakes per day of sufficient strength to cause damage to homes and buildings, with severe damage occurring 15 to 20 times per year.
There are 1800 thunderstorms at any given time across the earth surface; lightening strikes 100 times every second.
On average there 4 to 5 tornadoes per day or 600 1000 per year.
NATURAL HAZARDS: SOME FACTS & STATISTICS
Environmental or Natural Hazards/Disasters generally refers to geophysical events such as earthquakes, volcanoes, drought, flooding, cyclone, lightening etc., that can potentially cause large scale economic damage and physical injury or death. Environmental hazards are sometimes known as ‘Act of God.’
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Environmental Disasters
3. Definition:
An environmental disaster
is an incident which takes
place due to naturally or
human actions, results in
a harmful impact upon the
natural environment.
ENVIRONMENTAL DISASTERS
4. • There are two main
types of environmental
disasters.
1. Natural Disasters
1. Man-Made Disasters
TYPES OF ENVIRONMENTAL DISASTERS
5. NATURAL DISASTERS
A natural disaster is a major adverse
event resulting from natural processes
of the Earth. A natural disaster can
cause loss of life or damage property,
and typically leaves some economic
damage in its wake, the severity of
which depends on the affected
population's resilience and on the
infrastructure available. Examples
include floods, hurricanes, tornadoes,
volcanic eruptions, earthquakes,
tsunamis, storms, and other geologic processes
6. • Earthquake :
A sudden violent shaking
of the ground, typically
causing great destruction,
as a result of movements
within the earth's crust or
volcanic action.
TYPE OF NATURAL DISASTERS
7. • Volcanic eruptions:
Volcanic eruptions happen when lava and gas are discharged
from a volcanic vent. The most common consequences of this
are population movements as large
numbers of people are often forced
to flee the moving lava flow. Volcanic
eruptions often cause temporary food
shortages and volcanic ash landslides
called Lahar.
TYPE OF NATURAL DISASTERS
8. • Cyclone
A system of winds rotating
inwards to an area of low
barometric pressure, with
an anticlockwise (northern
hemisphere) or clockwise
(southern hemisphere)
circulation; a depression.
TYPE OF NATURAL DISASTERS
9. • Flood:
An overflow of a large
amount of water beyond
its normal limits, especially
over what is normally
dry land.
TYPE OF NATURAL DISASTERS
10. • Drought:
A prolonged period of
abnormally low rainfall,
leading to a shortage of
water. It can have a
substantial impact on the
ecosystem and agriculture
of the affected region and
harm to the local economy.
TYPE OF NATURAL DISASTERS
11. • Tornado:
A mobile, destructive vortex
of violently rotating winds
having the appearance of a
funnel-shaped cloud and
advancing beneath a large
storm system.
TYPE OF NATURAL DISASTERS
12. • Tsunami:
A long, high sea wave
caused by an earthquake,
the displacement of a large
volume of water or other
disturbance.
TYPE OF NATURAL DISASTERS
13. • Sinkhole
A cavity in the ground,
especially in a limestone
formation, caused by
water erosion and providing
a route for surface water to
disappear underground.
TYPE OF NATURAL DISASTERS
14. • Avalanches and landslides:
The main difference between landslide and avalanche is
that landslides occur on land whereas avalanches occur on
snow. Both landslide and avalanche refer to the movement
of a large stationary mass under the force of gravity.
These are very dangerous processes that can cause
manydamages and deaths.
TYPE OF NATURAL DISASTERS
15. • Hailstorms
A hailstorm is an unusual
weather phenomenon in
which balls of ice, called
hail, fall from the sky. The
ice balls are nothing more
than solid precipitation that
will form under certain conditions.
TYPE OF NATURAL DISASTERS
16. • cold and heat waves:
Heat waves are periods of
unusually high temperatures,
usually lasting three days to
three weeks. Cold snaps are
commonly three days to three
weeks in duration, with
temperatures usually falling below -15°C (5°F).
TYPE OF NATURAL DISASTERS
17. • Wildfire:
A wildfire, bushfire, wildland
fire or rural fire is an
unplanned, unwanted,
uncontrolled fire in an
area of combustible
vegetation starting in
rural areas and urban areas.
TYPE OF NATURAL DISASTERS
18. • Blizzard:
Blizzard, severe weather
condition that is distinguished
by low temperatures, strong
winds, and large quantities
of either falling or blowing
snow.
TYPE OF NATURAL DISASTERS
19. • Thunderstorms and lighting:
Every thunderstorm produces lightning, which
kills more people each year than tornadoes. Heavy
rain from thunderstorms
can lead to flash flooding.
Strong winds, hail, and
tornadoes are also dangers
associated with some
thunderstorms.

LIST OF NATURAL DISASTERS
21. THE CAUSES OF NATURAL
DISASTERS
The causes of natural disasters are many. Human
activities play a role in the frequency and severity of
disasters. A natural disaster is a disruption in the
balance of the environment. The human factor raises
the cost, in both property damage and loss of life.
Understanding the causes of natural disaster can
provide clues to their prevention. Not all natural
disasters can be prevented. Each natural disaster has
its own factors and complications. Understanding the
basic principles of ecology can provide keys to
lessening their effects. Nature evolved with natural
disasters and disturbance. The best prevention is
looking at the strategies found in nature.
22. MAN MADE DISASTERS
A man-made disasters is a disaster resulting
from human intent, negligence, or error.
Manmade disasters can
be both intentional and
unintentional. It results
in huge loss of life and
property. It further
affects a person's mental,
physical and social
well-being.

REASONS FOR MAN MADE
DISASTERS REASONS
24. 1. Nuclear Disasters:
A nuclear and radiation accident is defined by the
International Atomic agency as an “event that has led to
significant consequences to people,
the environment or the facility”.
Examples include lethal effects to
individuals, large radioactivity
release to the environment, or
“reactor core melt.”
TYPES OF MAN MADE DISASTERS
25. • Precautions of Nuclear Disasters:
Common indicators of these disasters are vomiting ,
nausea , dizziness etc. Don’t look at fire as it causes
instant blindness Close all doors and windows as
radioactivity doesn’t penetrate into solid structures
Cover all food and water and listen govt. orders.
TYPES OF MAN MADE DISASTERS
26. • Chemical Disaster:
Disasters that are caused by
the excessive use and misuse
of chemicals in industries are
called chemical disasters . The
irresponsible handling of
powerful chemicals can cause
widespread devastation.
TYPES OF MAN MADE DISASTERS
27. • Precautions Chemical Disaster:
Industries using harmful and powerful chemicals
should be located far away from residential areas
There should be surveys to
keep a check on their activity
The govt. should formulate
an emergency plan to in case
of an accident Pollution levels
should be checked and maintained.
TYPES OF MAN MADE DISASTERS
28. • Biological Disaster:
These are referred as poor mans nuclear bomb as
these are easy to manufacture , transport and have the
ability to kill hundreds
and thousands of people.
They are delivered using
dusting airplanes or small
perfumes atomizers . They
have ability to generate
immediate effects.
TYPES OF MAN MADE DISASTERS
29. • Precautions Of Biological Disaster:
The WHO should lay emphasis on prohibition
against biological warfare We should immediately
get away from an suspicious
thing Cover your mouth with
a wet cloth Listen to T.V.
and Radio for further
GOVT. instructions.
TYPES OF MAN MADE DISASTERS
30. • Fire Accidents:
Accidents that are caused
due to fire are quite common . Fire results in
heavy damage both in terms
of life and property . Loss of
life is high in a crowded
building.
TYPES OF MAN MADE DISASTERS
31. • Precautions of Fire Accidents:
The main reason is poor wiring and faulty electrical
equipment , leaking gas or carelessly thrown cigarettes
and matches The main power
supply source is good condition.
Wire should be properly covered
Inflammable things should be
kept out of reach of children Power
points shouldn’t be overloaded.
TYPES OF MAN MADE DISASTERS
32. • Travel Accidents:
Travel accidents are quite
common. An accident which
involves a no. of people
becomes a disaster. Eg of
these disasters are air crashes ,
train or vehicles collisions ,
capsizing of boats etc
TYPES OF MAN MADE DISASTERS
33. • Precautions OF Travel Accidents:
All efforts should be made to carry victims to
nearby hospital If possible, first aid can be given
to victims It is the duty of
people present there to get
trapped people out If we
smell fuel at accident site ,
warn people and don’t light fire.
TYPES OF MAN MADE DISASTERS
34. • Terrorism:
This is another type of
disaster that results in
loss of life and property.
Terrorists use violence and
strike without warning.
They use bombs , guns
etc to terrorize people
TYPES OF MAN MADE DISASTERS
35. • Precautions Of Terrorism:
We must inform police if we come across any
suspected group of people We must stay away
from any suspicious things
and inform police about that.
Do not accept packages from
strangers Do not leave luggage
unattended while travelling
TYPES OF MAN MADE DISASTERS
