1. Essay about Natural Hazards
Introduction
Floods are a natural hazard. There have been many devastating floods in the past decade.
Different countries have reacted differently during and after the floods have occurred. Some
countries have needed economic help during these times. Some countries were able to give
detailed warning and saved many lives in doing so. Developed countries have the money to warn
its people of any floods or other natural hazards which may affect a community. Developing
countries often do not have the resources or money to start a rescue of people after the disaster
occurs. They have to rely on the United Nations (UN) or developed countries to donate money.

These factors made the flooding of 2010 more catastrophic than previous years. The difference
between the two floods was the type of landscape where the flood occurred. Pakistan does not have
mountains or any other features in the land to limit the flood plain. The heavy rain caused both
floods.
Impacts
The impacts of the floods were very different. The life lost in Pakistan was estimated at 1,540
people while in Australia the loss of life was around 35 people. The loss of life in Pakistan was
due to poor warning and failure to help those who were trapped. The structure of the houses in
Pakistan was not built to stay together in a flood. The Australian houses in flood areas are built
with waterproof walls and to only have the garage downstairs. The Australian is estimated to cost
$6 billion to rebuild all of the structures which were damaged or destroyed during the floods. The
Pakistani floods were estimated to cost around $9 billion. There are many areas in Pakistan were
flooding occurs every year and the people know how to rebuild their homes. There are some
positives of floods. Pakistan needs to be flooded every year otherwise crops will not grow. The
soil needs the flood water every year so it has nutrients for crops to grow. The Australian
environment does not need to be flooded every year. Australia has four seasons while in Pakistan
there is a wet and dry season. Australia experiences rain in every

The most commonly referenced of Natural Disasters are Tornadoes. A Tornado is a violent,
dangerous, rotating column of air that is in contact with both the surface of the earth and a
cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes come in many
shapes and sizes, but are typically in the form of a visible condensation funnel, whose narrow end
touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind
speeds less than 110 miles per hour, are approximately 250 feet across, and travel a few miles
before dissipating. The most extreme can attain wind speeds of more than 300 mph, stretch more
than two miles across, and stay on the ground for dozens of miles. Some of the most violent
tornadoes develop from super cell thunderstorms. A super cell thunderstorm is a long–lived
thunderstorm possessing within its structure a continuously rotating updraft of air. These storms
have the greatest tendency to produce tornadoes, some of the huge wedge shape. The super cell
thunderstorm has a

floods
Thousands of years ago before people built towns and planted crops, rivers cut deep canyons and
molded the continents. Often these rivers overflowed their banks and flooded the surrounding
areas, depositing mineral rich silt and soil in the surrounding plains and valleys. Because of the way
floods enrich soil some of the first cities were built along rivers. The most important ones grew
along the Indus River in Pakistan; the Nile in Egypt; the Yellow River in China; and the Tigris and
Euphrates in the Middle East. These rivers floodplains are called the "cradles of civilization".
(Michael Burgan &Robin Doak) Even though floods happen everywhere, there are only four types
of floods. River floods occur along rivers and usually...show more content...
These earthquakes cause tsunamis, which are huge waves. Tsunamis travel long distances across the
ocean before reaching land where they flood the coasts, drown people, and smash buildings. (Dennis
Fradin) Volcano eruptions can also cause tsunamis like in 1883 when Krakatoa erupted killing
37,000 people making it the worst tsunami in history. China is the largest and most populated
country on the earth. It is also where the worst flood in history occurred. In 1887 the Yellow River
toped its seventy–foot–tall levees and flooded eleven cities and hundreds of surrounding villages.
This flood became the deadliest flood ever by killing at least 900,000 people. Thousands of
square miles of farmland was covered in water that sometimes stood twenty feet deep over farm
houses. It took two years for this much water to recede. With crops washed away there was little
to eat; it is not known how many starved to death. In 1889 Johnstown Pennsylvania flooded.
Fourteen miles away from Johnstown the Little Conemaugh River had been dammed to form
Lake Conemaugh. The dam was owned by a country club and was known to be in poor condition.
The members sailed and fished on the lake but did little to repair the dam. May 30, 1889 was
Memorial Day and it rained hard. The river and lake rose quickly and the next day the water topped
the dam and spilled over

Management before the floods in Malaysia is based on the Standard Operating Procedure (SOP ) as
determined by the NSC to agencies like Department of Irrigation and Drainage (DID), Public Works
Departments (JKR), Department of Meteorology and Local Authorities (PBT) includes two steps,
namely, structured and unstructured. Structural measures adopted in Malaysia are like dams and
dykes to control flood flows and non–structural measures are such as land use planning and flood
forecasting and warning systems to mitigate the effects of floods (Chan, 2012; Khalid, & Shafiai,
2015). Structural measures implemented to reduce the danger of flooding so as not to pose a
greater hazard to people in the flood plain. Agencies involved in the success of...show more content...
In addition, the short message system (SMS) is also provided to warn employees of related
government agencies such as the Police, the Army, the Malaysian Meteorological Department
(JMM), Civil Defense Department, the Department, and National Security Division (BKN) in the
Prime Minister and other agencies involved (Jabatan Pengairan dan Saliran, 2013). The
Meteorological Department has also provided a weather forecast web site to facilitate public access
to current weather conditions. In 2001, Malaysia has introduced 'Manual Saliran Mesra Alam'
(MSMA) to be used as a tool in integrated flood management (Chan, 2012; Musa, Chan, Ku
Mahamud, Karim, & Zaini, 2013). In contrast, an example of which is seen nonstructural methods
are effective flood forecasting and warning system (Jabatan Pengairan dan Saliran, 2013). The
methods used for the management of flood disclosed before it has been shown that Malaysia has
certainly had an initiative to reduce the impact of floods on human health and life at risk areas.
Management of flood victims during and after the flooding situation in Malaysia also is based on
Directive No. 20. According to MKN (2012), during the current disaster management involves a
number of rescue agencies on the scene as the Special Search and Rescue Team Malaysia
(SMART), the Royal Malaysian Police (PDRM),
