An earthquake, also known as a quake or tremor, is a sudden violent shaking of the earth that can be very destructive, collapsing buildings and destroying entire geographical areas. Earthquakes are such powerful natural phenomena that they can claim a large number of lives in a single event. Earthquakes, unlike other natural disasters such as floods and drought, are a sudden activity that does not give us time to prepare, resulting in the greatest number of casualties at one time. Here we have provided both long and short speech on earthquake in English.
Long and Short Speech on Earthquake in English
Long Speech on Earthquake
Today, I am here to deliver a speech on earthquake. An earthquake is the shaking of the earth caused by the sudden shifting of pieces of the Earth's crust. In comparison to the hot rock deeper inside, the crust, or thin outer layer, is mostly cold and brittle rock. This crust is riddled with large and small cracks known as faults.
Although these faults can be hundreds of miles long, the cracks are usually invisible because they are buried deep underground and the pieces of crust are compressed together very tightly.
We frequently read in the news that an earthquake has occurred in a specific location. We learn that a large number of people have died.
During an earthquake, there are earth tremors. These tremors can be mild and not cause concern at times. The tremors can be quite severe at times. People can feel the ground sway beneath their feet.
Earthquakes happen as a result of a sudden release of stored energy. This energy has accumulated over time as a result of tectonic forces within the earth.
Most earthquakes occur along faults in the upper 25 miles of the earth's surface when one side of the fault rapidly moves relative to the other. Shock waves (seismic waves) are caused by this sudden motion and travel through the earth from their point of origin, known as the focus.
Now, the question arises: what are the causes of earthquake? It is the ground motion caused by seismic waves that are referred to as an earthquake. Every year, thousands of earthquakes are felt by people, with over one million strong enough to be recorded by instruments.
Strong seismic waves can cause significant local damage and travel long distances. Even weaker seismic waves, however, can travel long distances and be detected by sensitive scientific instruments known as seismographs.
Geologists have devised several methods for determining the magnitude of an earthquake. The Richter scale, which measures the energy released in an earthquake by measuring the size of the seismic waves, is one of the most common methods. The Mercalli scale, which measures the effects of an earthquake, such as shaking and visible damage.
The next important thing to be aware of is the effects of earthquakes. The first one is ground shaking/tremors. In a large earthquake, violent ground shaking could last for up to a minute. It may be difficult to stay upright during the earthquake. In the weeks following the main quake, several hundred aftershocks were felt. The second one is landslides. The consequences of earthquake-induced landslides can range from severely weakened foundations and structural failures to total destruction.
The last one is fault movement. A fault rupture could result in several metres of horizontal and/or vertical movement. Buildings, roads, water mains, gas lines, and power cables that cross the fault line may be displaced as a result.
So, what should we do to protect ourselves?
We should (i)Stay Calm. (ii)Follow the Earthquake Family Plan. (iii)Duck and Cover and (iv)Do not try to enter or leave any building during the earthquake. After the earthquake is over, we should (i)Check for injuries. (ii)Listen to the radio and/or television for important information. (iii)Not drink the water until told that it is safe. (iv) Check our location for possible damage and safeness. (v)Relocate if necessary. (vi)Call out-of-town friends and family to update them on your safety and location.
Short Speech on Earthquake in English
A natural disaster is an earthquake. It is strange, but true, that the majority of earthquakes appear to occur during the winter season. Scientists believe it is caused by volcanoes and moving rocks beneath the earth's surface.
An earthquake can be a terrifying event. It appears out of nowhere and lasts only a short time. It only lasts a few seconds, but those few seconds are enough to frighten anyone mentally, physically, and socially.
They are caused by unusual movements of Earth's tectonic plates.
Seismology is the study of earthquakes. Earthquakes are usually short-lived, but they can happen again. The abrupt release of tension in the tectonic plates sends energy waves through the Earth.
So, what are the different types of seismic plates? Seismic waves form when a large section of rock shifts abruptly. This rocking movement generates at least three different types of waves: P (primary) waves: When a rock is pushed or pulled forward or backwards, pressure waves are produced. The fastest wave produced by an earthquake travels down into the earth rather than along the surface.
Secondary (S) Waves: Shear waves produced when a rock is shaken or whipped from side to side, similar to a slithery snake's wavy motion. Secondary waves, the second-fastest waves produced by an earthquake, travel downward into the earth rather than along its surface.
Surface (L) Waves: Movement of the earth's surface up and down (rolling) or side to side.
Surface waves, the slowest earthquake waves, travel along the earth's surface rather than deep within it. Despite being the slowest of the earthquake waves, L waves typically cause more damage to society than P or S waves. L waves are named after a geologist who investigated them. These three types of waves are produced by every earthquake.
Now, let us educate ourselves about the do’s and don’t during an earthquake. If you are indoors, Take refuge beneath a table or bench. If there isn't a table or desk, sit against a wall away from objects that could fall on you, and avoid windows, bookcases, and tall, heavy furniture. Wait in your safe location until the ground stops shaking, then check to see if you are hurt. Examine the people around you as well. Move slowly and keep an eye out for anything that has fallen. Soon after, there may be aftershocks or smaller earthquakes. So, be ready. If you need to leave the building after the shaking has stopped, take the stairs rather than the elevator.
Stay safe, follow the instructions and educate yourself and the people around you.
10 Lines for Writing an Essay on Earthquake
An earthquake is a natural calamity that can occur at any moment of time and at anywhere on the earth’s surface.
In comparison to other natural calamities, an earthquake is the most powerful and strong calamity which can destroy a big area.
The earthquake has a long and devastating history from ancient times and the irregularity of its occurrence makes it more fearful.
If we talk about earth, the earth’s crust consists of various unparallel solid rocks which slowly move deep inside.
The surfaces on which the entire world stays are called plates and those plates collide with each other and produce an earthquake.
The field of science in which earthquakes are studied is ‘seismology’ and it also determines the intensity and magnitude of an earthquake.
The volcanic eruption which releases lava, gases, etc which creates pressure and imbalance inside the earth may also result in earthquakes.
To protect oneself from an earthquake, one should stay inside or outside the house, but not too close to the building, lampposts, windows, and so on.
People should stand close to the wall or hide by entering any furniture such as a bed, chair, or table.
During an earthquake, always use the stairs to exit the building and reach open space; never use a lift.
To summarise, an Earthquake is a massive and terrifying natural phenomenon. It demonstrates humanity's frailty in the face of nature. It is a huge occurrence that has taken everyone by surprise. Above all, an earthquake only lasts a few seconds but can cause unfathomable damage.
