A disaster is defined as a sudden event that causes widespread human and material losses exceeding a community's ability to cope. Disasters can be natural, caused by earthquakes, volcanic eruptions, cyclones, floods, droughts or tornadoes. They can also be man-made, such as chemical spills, nuclear accidents, acts of terrorism, or other industrial and transportation incidents. Preparing for disasters includes having detection systems, incident response plans, safety measures, hazard assessments, support systems, medical triage and evacuation routes. Both natural and man-made disasters can have severe negative effects including loss of life, property damage, health issues and environmental degradation.
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.

This slide presentation is part DYUTI 2010 preconference series. This slides discuss various environmental disasters. Prepared and Presented by Kochubaby Manjorran
Tsunami is a Japanese word Tsu means ‘harbour’ and nami means ‘wave’.
They are called tidal waves but they have actually nothing to do with the tides. However their appearance from shore is similar to rapidly rising or falling tides.
Tsunami is a series of wave created when water is moved very quickly.
Tsunami is gravity wave system, triggered by vertical disturbances in ocean. They are long waves sometime with hundreds of miles b/w their crests, just like the concentric waves generated by an object dropped into a pool.
First tsunami was recorded in 1480 B.C. in eastern Mediterranean, when the Minoan civilization was wiped out.
A large tsunami accompanied by the earthquake of Lisbon in 1755.
The Kutch earthquake of June 16, 1819 generated strong tsunami which submerged the coastal areas and damage to ships and country made boats of fishermen.
North and South American records have dated such
events back to 1788 for Alaska and 1562 for Chile. Records of Hawaiian tsunami go back to 1821.
Tsunami hits the Mona Passage off Puerto Rico in 1918, grand banks of Canada in 1929.
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

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
2. 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.

What does Disaster stand for ?
4. Disasters are of two types :
Natural disasters,
Man-made disasters.
Types of disastres
5. Natural Disasters are of the following type:
Earthquakes
Volcanic eruptions
Cyclones
Floods
Droughts
Tornadoes
Tsunami
Types of Natural Disasters
6. Earthquakes
An earthquake is a shaking of the ground caused by the sudden breaking and
movement of tectonic plates of the earth's rocky outermost crust. The edges of the
tectonic plates are marked by faults. Most earthquakes occur along the fault lines
when the plates slide past each other or collide against each other.
The shifting masses send out shock waves that may be powerful enough to alter the
surface of the Earth, thrusting up cliffs and opening great cracks in the ground and
cause great damage ... collapse of buildings and other man-made structures, broken
power and gas lines, landslides, snow avalanches, tsunamis.
7. Volcanoes can cause widespread destruction and consequent disaster in several ways. The
effects include the volcanic eruption itself that may cause harm following the explosion of the
volcano or the fall of rock. Second, lava may be produced during the eruption of a volcano. As it
leaves the volcano, the lava destroys many buildings and plants it encounters. Third, volcanic ash
may form a cloud, and settle thickly in nearby locations. In sufficient quantity ash may cause
roofs to collapse under its weight but even small quantities will harm humans if inhaled. A
specific type of volcano is the super volcano.. The main danger from a super volcano is the
immense cloud of ash which has a disastrous global effect on climate and temperature for many
years.
Volcanic Eruptions
8. Cyclone in meteorology refers to any low pressure area with winds spiraling inwards. Cyclones rotate clockwise
in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. Cyclone is the general term for a
variety of low pressure system types, such as tropical cyclones, extra tropical cyclones and tornadoes.
The largest of the low-pressure systems are the extra tropical cyclones and the cold-core polar cyclones which lie
on the synoptic scale which in meteorology is a horizontal length of 1000 km or more. The Warm-core cyclones
are the tropical cyclones, mesocyclones, and the polar lows that lie within the smaller mesoscale. The
Subtropical cyclones are intermediate in size. Cyclones have also been on other planets outside of the Earth,
such as Mars and Neptune. For example the Great Red Spot of Jupiter and the Great Black Spot of Neptune.
Cyclones are also referred to as hurricanes and typhoons. They consist of the eye, eye wall and rain bands.
The calmest part of a cyclone is its eye which is at the middle of a cyclone.
Cyclones
9. A flood is an overflow of an expanse of water that submerges land. The Floods
directive defines a flood as a temporary covering by water of land not normally
covered by water. In the sense of "flowing water", the word may also be applied to
the inflow of the tide. Flooding may result from the volume of water within a body
of water, such as a river or lake, which overflows or breaks levees, with the result
that some of the water escapes its usual boundaries. While the size of a lake or
other body of water will vary with seasonal changes in precipitation and snow melt,
it is not a significant flood unless the water covers land used by man like a village,
city or other inhabited area, roads, expanses of farmland, etc.
Floods
10. Droughts occur in virtually all climates. Of all the weather-related
phenomena that can cause severe economic impacts in the United States,
droughts come in second only to hurricanes, according to the National
Climatic Data Center. But unlike hurricanes, which are easily identified and
straightforward to classify in terms of wind speeds, droughts are much
tougher to define. Most people think of a drought as a period of unusually
dry weather that persists long enough to cause problems such as crop
damage and water supply shortages.
Droughts
11. A tornado is a violent rotating column of air extending from a
thunderstorm to the ground. The most violent tornadoes are capable of
tremendous destruction with wind speeds of up to 300 mph. They can
destroy large buildings, uproot trees and hurl vehicles hundreds of yards.
They can also drive straw into trees. Damage paths can be in excess of one
mile wide to 50 miles long. In an average year, 1000 tornadoes are
reported nation wide. Most tornadoes form from thunderstorms.
Tornadoes
12. A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, generally
an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions landslides, glacier
calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a
tsunami.
Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than
appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. Tsunamis generally
consist of a series of waves with periods ranging from minutes to hours, arriving in a so-called "wave train".
Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to
coastal areas, their destructive power can be enormous and they can affect entire ocean basins; the 2004 Indian
Ocean tsunami was among the deadliest natural disasters in human history with at least 290,000 people killed or
missing in 14 countries bordering the Indian Ocean.
Tsunami
13. 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.
Causes of Natural Disasters
14. 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.
Man Made Disasters
15. The causes of man made disasters are:
Reasons for Man Made Disasters
Reasons
ignorance 52%
unawreness 20%
illiteracy 40%
carelessness 42%
16. Man made disasters can be the following:
Nuclear disaster
Chemical disasters
Radiological emergencies
Terrorism
Examples of Man Made Disasters
18. One should not look at the fire as it causes instant
blindness.
Close all doors and windows as radioactivity does
not penetrate into solid structures.
Cover all food and water.
Nuclear Accidents
19. Do not panic, evacuate calmly and quickly perpendicular to wind
direction through the designated escape route
Keep a wet handkerchief or piece of cloth/ sari on face during
evacuation
Do not consume the uncovered food/ water etc open to the air,
drink only from bottle
Provide correct and accurate information to government official.
Inform others on occurrence of event at public gathering places
(like school, shopping centre, theatre etc.).
Don’t pay attention to the rumours and don’t spread rumours.
Chemical Disasters
20. Take cover yourself Keep your condition till the flash, hot air, and flying and
falling debris
Be aware of intense flash-light coming from the explosion of a nuclear
weapon.
Then, head urgently for the nearest shelter without panic. You have 30-60
min before you reach the shelter.
Protect your mouth and nose with swab/cloth etc.
You must wash your hands, face, hairs, and other uncovered part of your
body.
Take the necessary equipment with you and enter the shelter.
Radiological emergencies
21. Terrorism is the use of fear and acts of violence in order to intimidate
societies or governments. Many different types of social or political
organizations might use terrorism to try to achieve their goals. People
who do terrorism are called terrorists.
It is difficult to explain terrorism. Terrorism has no official criminal law
definition at the international level. Common definitions of terrorism
refer to violent acts which are intended to create fear (terror); are done
for a religious, political, or ideological goal; and which target civilians.
Some definitions now include acts of unlawful violence and war. The
use of similar tactics by criminal gangs is not usually called terrorism,
though these same actions may be called terrorism when done by a
politically motivated group.
Terrorism
22. Example of man made disaster…
London smog
The Al-Mishraq Fire
The Nuclear Power Plant Explosion in Chernobyl
The Kuwait Oil Fires
The Destruction of the Aral Sea
23. The disasters has only caused loss to life and property,
the animals face the threat of extinction, good yielding
land turns into a waste land humans suffer from severe
ailments every where there is a health problem.
