Speech about earthquakes essay
Look at this chart, here are five columns, they are magnitudes, frequency, description, example and energy release.
Earthquake Design - A Conceptual Review 2 4. With the cost of repairs increasing the destruction.
Speech on earthquake
You must ensure that your head and torso are protected. Most of the earthquakes were mild but some of them left people in shock with destruction. Aftershocks are formed as the crust adjusts to the effects of the main shock. P Waves shake the ground vertically and horizontally.

What is Volcanic Earthquake? Secondly, I want to talk about where are earthquake located, the first picture is the plate boundary. Some of the earthquakes are less harmful due to low frequency and some of them are so violent that they could destroy everything. Select Page Earthquake Essay Earthquake occurs due to disturbance in the tectonic plates that lie under the surface of Earth. Help those caught inside or in need if you can. An earthquake is a sudden movement of the Earth, caused by the rough release of strain that has accumulated over time. The quake felt on the surface is always the result, not the cause of some underground geologic process, and in many cases the damage done is immense The earthquake that occurred in Sichuan province, China was one of the phenomenons that will be unforgettable for Sichuan people
In this modern times, people are required to be constantly vigilant and be able to reduce massive losses and deaths caused by an earthquake.
These red dots represent epicenter of earthquakes that have occurred over the past 50 year.
Though, this cannot be full proof however efforts in this direction can certainly help bring down the magnitude of losses. The conclusion will be completed in the next phase. Human Activities Man is known to influence various natural activities and earthquakes are no exception.
Causes of earthquake
Collapse Earthquake This type of earthquake is caused due to the explosion of rocks. Earthquakes are caused by a collision of two plates in the earth. Remember: L waves are always the last to arrive. Earthquakes greatly impact various locations around the world. Hot lava, poisonous gases and volcanic ash come out by way of volcanic eruptions and can cause vast destruction. The one thing man can't do is to control Mother Nature. The underground surface along which the rock breaks and moves is called a fault plane. It may be very difficult to remain standing during the earthquake. Even before seismographs in early times, there are records and accounts of mysterious ground shaking. Relative Seismicity 5 6. Geologists have developed several ways of measuring the size of an earthquake. Landslides d. In seismic language, the point immediately below where the rocks break is called the focus and the point immediately above is called the epicenter.
We should rather act wisely. Most earthquakes happen along the Pacific Ring of Fire but the biggest ones mostly happen in other places.
P and S travel downward into the earth, and L waves travel along the top of the crust.
More often, natural calamities leave people astonished and anesthetized and make them helpless after it stops. But before the camp starts, I would like to discuss some information about the occurring of an earthquake because it has became very important to understand the reason behind an earthquake.
Short paragraph on earthquake
An earthquake can be defined as vibrations produced in the earth's crust. Since it is almost impossible to forecast and avoid the occurrence of earthquakes, we must prepare ourselves to lower the losses caused by these. But within these fleeting moments terrible havoc is caused to life and property. Considered to be an aftermath of the April earthquake, it took away lives and injured more than people. This is the time when we all have to come together to fight against such disasters like earthquake and make our earth green again. Let us specify the damage of magnitude 8 and 9. This releases the stored energy as shock wave s. The underground surface along which the rock breaks and moves is called a fault plane. Earthquakes can cause a lot of damage to homes and places so it is important to know where it has happened. Now, there are some of the important measures that should be taken during an earthquake for being safe as possible. The earthquake that occurred in Sichuan province, China was one of the phenomenons that will be unforgettable for Sichuan people First of all, I would like to thank the school authority for inviting me to the annual celebration of your school. From the earthquake features discussed, we can see that despite the Seddon earthquake having a greater magnitude and similar type of fault movement, it was the fact that the Christchurch earthquake carried a lot more power and force with its initial ground movement and shaking, and its continual aftershocks, that the effects of this earthquake were much worse than the Seddon earthquake. It occurred in the afternoon and its resulting tsunami affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska.
