Natural Hazards

By Micah Moen 0 Comment March 23, 2020


Natural hazards are extreme natural
events that can cause loss of life, extreme damage to property, and disrupt
human activities. They can happen anywhere in the world and can have
economic, social, and environmental consequences. This is why it is important
to be educated about natural hazards and what can be done to reduce the impact of
them. A flood is an overflow of water on land which is usually dry. Flash floods
can happen quickly. During a flood people should move themselves and their most
precious belongings to higher ground quickly. Tropical cyclones are storms
with strong winds and heavy rains. While most tropical cyclones stay out in the
sea, others pass over land. These cyclones form when moist ocean air rises. A
landslide includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows. The biggest reason for landslides
is that gravity moves material down a slope. An avalanche occurs when there is
too much snow on a mountain. Some of the snow may fall, which can damage things in its path. They may be dangerous to people partaking in winter sports, like skiing.
Wildfires occur on every continent except Antarctica. They can occur naturally but
many are caused by humans, both accidentally and on purpose. Wildfires
can cause damage to human and property life. A volcano is a mountain where lava
comes from a magma chamber underground When there is a lot of pressure a
volcano erupts. Eruptions cause lava, rocks, dust, and ash to be thrown out of
the volcano. A sudden release of energy in the Earth’s crust can cause an
earthquake. They shake the surface of the Earth and are usually quite brief,
although they may repeat. Large earthquakes can take down buildings and
hurt people inside. Usually a tsunami starts suddenly. A tsunami contains a
series of fast-moving waves in the ocean. They are caused by earthquakes or
volcanic eruptions. Sadly, tsunamis can damage houses and
even destroy whole towns A storm surge is a sudden rise of water
hitting areas close to the coast. Strong storm surges can flood coastal towns and destroy homes. When an area gets less than its normal
amount of rain, a drought can occur. Because crops and plants need water to
grow and animals need water to live, droughts can be dangerous.
Insect plagues are another type of natural hazard. Locust plagues are the
most common, and these animals cause havoc by passing through in large groups
and eating crops. An epidemic is when a large number of people get a disease at
the same time. Diseases can spread through insects, airborne transmission, or
foods and water. Examples of epidemic diseases include influenza ,the Black
Death, and malaria. To reduce the impact of natural hazards, the following
elements can be put into place: awareness and education, preparedness for emergency
response and recovery, prediction and warning systems, and community or
international cooperation. People with poor education or limited access to
education are most vulnerable during a natural hazard because they may be
unaware of how to deal with the crisis. Therefore, awareness and education is one of the key factors of reducing the impact of natural hazards. Preparedness
for emergency response, recovery, and reconstruction can reduce immediate
losses caused by natural hazards and minimize the long term social, economic,
and environmental damages they cause. Prediction and warning advances have
been a major factor in the decline of disaster-related deaths in the United
States over the past half-century, particularly those resulting from severe
weather, wildfires, and floods. Nevertheless, significant gaps still
exist in the capability to predict certain hazards and to deliver warnings
to those who need them. Cooperation is essential to the success of reducing the
impact of natural hazards. The involvement and commitment of
individuals, communities, and professional organizations will be crucial to
reducing vulnerability to natural hazards.
