This is a presentation on the names of some disasters and effects and precautions that are to be taken.

1. Lightning Tornado Thunderstorm Storm

2. IT’S DISASTER TIME
LIGHTNING
Let’s start our theory with Lightning-
Lightning is an electrical discharge caused by imbalances between
storm clouds and the ground or within the clouds themselves. Most
lightning occurs within it. This heat causes surrounding air to rapidly
expand and vibrate, which creates the pealing thunder we hear a
short time after seeing a lightning flash. When it strikes it can cause a
disastrous death but survivors may be lucky to escape death, but most
experience long-term ailments. Common after-effects of a lightning
strike include pain, headaches, seizures, depression, memory loss,
respiratory distress, loss of senses, and brain damage.
The safety measures to be taken when a lightning strikes are-
•Immediately get off elevated areas such as hills, mountain ridges, or peaks.
•Never lie flat on the ground. ...
•Never shelter under an isolated tree.
•Never use a cliff or rocky overhang for shelter.
•Immediately get out of and away from ponds, lakes, and other bodies of water.

3. IT’S DISASTER TIME
TORNADO
Let’s start our theory with Tornado-
A tornado is a violently rotating column of air extending from the
base of a thunderstorm down to the ground. With winds of over
350 kilometers (over 200 miles) per hour, tornadoes can flatten
houses and lift cars off the ground. The flying debris is the most
dangerous part of a tornado to people. It can cause severe
injuries and lead to loss of life. Statistically, tornadoes cause
1,500 injuries each year. Averagely, 80 deaths devastating in
tornadoes are recorded each year.
The safety measures to be taken while a tornado are-
•Go to the basement or an inside room without windows
on the lowest floor (bathroom, closet, center hallway).
•If possible, avoid sheltering in a room with windows.
•For protection, get under something sturdy as a heavy
table.
•Do not stay in a mobile home.

4. IT’S DISASTER TIME
THUNDER STORM
Let’s start our theory with Thunder storm-
A thunderstorm, also known as an electrical storm or a lightning
storm, is a storm characterized by the presence of lightning and its
acoustic effect on the Earth's atmosphere, known as thunder.
Relatively weak thunderstorms are sometimes called
thundershowers. It is accompanied by lightning and thunder. It may
also have gusty winds and often brings heavy rain. Some
thunderstorms can also bring tornadoes and/or hail. During winter,
localized heavy snow showers may also have thunder and lightning.
The safety measures to be taken during thunderstorm
•Avoid water during a thunderstorm. Lightning can travel through
plumbing.
•Avoid electronic equipment of all types. Lightning can travel through
electrical systems and radio and television reception systems.
•Avoid corded phones. ...
•Avoid concrete floors and walls.

5. IT’S DISASTER TIME
STORM
Let’s start our theory with Storm-
A storm is a violent meteorological phenomena in which there is heavy
rain, and wind due to moisture in the air. Hail and Lightning are also
common in storms. The rising temperatures produce strong upward
rising winds. These winds carry water droplets upwards, where they
freeze, and fall down again. When a center of low pressure develops with
the system of high pressure surrounding it. This combination of opposing
forces can create winds and result in the formation of storm clouds such
as cumulonimbus. Buildings and bridges can be destroyed, people can get
into difficulties in the water, and roads and railways can become
damaged. Power cables and telephone lines come down, crops are ruined,
and water and sewage supplies are affected.
The safety measures to be taken when there is a storm-
• Postpone outdoor activities until the storms have passed.
• If caught outside, take shelter in a sturdy enclosed building or hard
top automobile immediately.
• Avoid open spaces, isolated objects, high ground and metallic
objects.

6. IT’S INVESTIGATION TIME TO KNOW MORE FACTS
➢ There was a time when weather forecasters didn't report on tornadoes at all — in
fact, they weren't allowed to. In the late nineteenth century, the word “tornado”
was banned from American weather forecasts. These storms were thought to be
so terrifying that reporting on them might cause a panic.
➢ Typhoon Tip, known in the Philippines as Typhoon Warling, was the largest and
most intense tropical cyclone ever recorded.
➢ The area that experiences the most thunderstorm days in the world is northern
Lake Victoria in Uganda, Africa. In Kampala thunder is heard on average 242
days of the year, although the actual storms usually hover over the lake and do not
strike the city itself.
➢ Lake Maracaibo, lightning capital of the world. The lake attracts thousands of
lightning bolts per night.
➢ Green lighting indicates that a tornado might be on its way. This phenomena
occurs later in the day, when the sun gets closer to the horizon. Benjamin
Franklin discovered that lightning was caused by powerful electrical discharges in
the clouds.

7. THANK YOU
I must thank my teacher for assigning this project to our class just not for internal assessment but to gain
knowledge. From this project I have learnt the safety precaution to be taken when a disaster strikes.
