Both the continental and the oceanic crusts are bonded to the mantle to form a layer known as the lithosphere.
When the surface of the earth moves in response to heat and pressure from below, the shaking is called an earthquake. Earthquakes can happen in many places, but there are some areas where they are concentrated.
Earthquakes travel in ripples or waves across the earth and through the layers of the earth.
Seismology is the study of earthquakes and a seismologist is the scientist that studies earthquakes.
Geologists and seismologists use two different scales to measure how strong an earthquake is.
Humans developed many explanations for earthquakes before they had the understanding and instruments to study them scientifically. No one can predict earthquakes yet, nor prevent them, but you can protect yourself by preparing for one.
Now let us look at the four different layers of the Earth and the elements that make them up!!!
Now that you have read all those facts about the Earth, let's look at a diagram of the layers of the Earth! Answer: Scientists learn about the Earth by studying other planets, earthquakes and volcanoes and even by drilling into the Earth.
If a person were standing in just the right location and could see the surface of the earth during an earthquake, the ground would actually appear to be moving in a wave.

This leads to the characteristic shape of an earthquake on a seismogram with a small P wave followed by a larger S wave. The Richter Scale measures magnitude, the amount of energy released by an earthquake by measuring how big a shock wave is. You can read about some of these ideas about Earthquake Myths and Folklore.Here's a myth from Mongolia, China.
The shockwaves can travel through the surface of the earth but they can also travel through the layers of the earth where they bounce off of matter inside the earth. A tsunami happens when shocks from the earthquake create huge waves that come inland and strike communities along the ocean coast. One way scientists help is by comparing readings from widely spaced seismographic stations to determine the exact position of the earthquake's origin. The crust is the only part of the Earth that we can touch with our hands and see with our eyes everyday. The pressure from all the other layers make the inner core solid even though this layer is the hottest layer. Because the P wave is traveling faster, the time between the P and S wave increases away from the earthquake. A gigantic frog which carried the world on its back, twitched periodically, producing earthquakes. The two largest earthquakes in the lower 48 states in the last 45 years have been in Idaho (1959 and 1983). The estimates are that there are about 500,000 detectable earthquakes a year, 100,000 of those can be felt, and about 100 of them cause damage.

The epicenter of an earthquake is the place on the Earth's surface directly above the focus (more than one are called foci), which is the place inside the Earth where the quake originates.
As an earthquake is recorded, the pen jumps back and forth on the paper showing the intensity of the earthquake.
Liquefaction, ground displacement, flooding, tsunamis, and fire are all hazards of earthquakes. The inside of the Earth is still unbelievably hot because of nuclear reactions that are still going on. Rocks can also break under this stress and release huge amounts of energy in the form of shock waves. Some shock waves move through the ground before a volcano erupts, or underground where new crust is being formed. Learn more about the Richter Scale here.In addition to the Richter scale, scientists also use the Mercalli Intensity Scale to measure the amount and type of damage caused by the earthquake. It is very hard to imagine rocks bending and folding or even large areas of land sliding under layers of the ground.
