What caused the earthquake?
Introduction to Earthquakes:
Have you ever felt how the floor trembles under your feet? We call it an earthquake. If the floor suddenly shaking or moving, an earthquake will pass by. They are very strong and can cause a lot of damage.
Or they may be small and barely noticeable. But what will make the Earth tremble? We break it down and learn everything about earthquakes! This energy is stored in the Earth’s crust (the outer layer of Earth), and when it is released, the soil shakes. Earthquakes can occur anywhere in the world, but they are more common in certain places.
An earthquake can cause the soil to tremble, buildings collapse, and sometimes large cracks on the surface of the Earth. Earthquakes can cause other natural disasters, such as tsunamis and landslides.
The Earth is made up of different layers, and the movement of these layers can cause earthquakes.
1. Earth Crust: This is an extreme layer of the Earth. It is solid and made of rocks. We live in the crust, and that is where earthquakes occur.
2. Coat: The coat is beneath the crust. It is composed of high temperature semi-solid rocks that can move slowly.
3. Outer core: The outer core is made of liquid metal.
4. Inner Nucleus: The innermost part of the Earth is the inner core made of solid metal. It is divided into large sections called tectonic plates. Imagine the Earth’s crust as a giant puzzle. Each part is a structural plate. These plates are not set. Like a part of the puzzle, a rig, they move very slowly. Some of the largest plates are the Pacific Plate, North American Plate, and Eurasian Plate.
These tectonic plates move constantly, but they move slowly and are unaware. The movement of these plates is one of the main causes of earthquakes. When these plates push, pull, or slide against each other, voltage can build up. After all, this stress is released suddenly, which causes an earthquake. Convergence limit (collision plate)
A convergence boundary occurs when two tectonic plates collide or move. If these panels are pressed against each other, they can create a very powerful earthquake. A collision can push the plate into the air, forming a mountain. Alternatively, one plate may slip under the other plate. If these two plates continue to collide, an earthquake occurs in this area.
When two plates collide, a lot of stress accumulates, and when stress is released, energy trembles the soil. Different boundaries (plates moving away)
When two tectonic plates leave, different restrictions arise. When the plates fall apart, a new crust forms between them. This type of movement can also cause earthquakes, but the earthquakes here are usually smaller and less powerful than those caused by collisions. This creates a new crust and creates a gap in which small earthquakes occur.
At various boundaries, the plates move apart from each other, so magma can rise from the coat to fill the gap, but the plates may move smoothly and not cause earthquakes. Conversion limit (plates slide against each other).
Conversion limit occurs when two tectonic plates slide against each other horizontally. If the plate moves, it can get stuck due to friction. This means that stress builds up. This sudden energy frame causes an earthquake as the plates finally slide and move together. Earthquakes in this area occur due to friction between the two panels.
In the case of conversion limits, plate movements can cause earthquakes along errors and cracks on the surface of the earth. From this point on, energy from the earthquake spreads into the waves.
The point on the surface of the Earth directly above the focus is called the epicenter. The epicenter is often the place where earthquakes are most prominent. These waves are energy that travels the earth and trembles in the soil.
There are two main types of seismic waves.
1. Primary Waves (P-Waves): These are the fastest waves and allow you to hike both solids and liquids. The p-wave causes the floor to and backwards.
2.Second Secondary Wave (S-Wave): These waves move more slowly than P-Waves, allowing only solids to move. S-waves cause the soil to move from one side to the side or up and down.
As seismic waves move around the earth, you can manage the floor and feel it on the surface.
After and Conditions:
Small earthquakes may appear after a major earthquake. These small earthquakes are mentioned. They appear to allow the Earth’s crust to adapt to changes in the main earthquake. Preliminary reductions are less powerful than major earthquakes, but they could serve as a warning that a larger earthquake will arrive. Seismic maps record the intensity and length of seismic waves. Scientists can help you know how strong an earthquake is and how deep it is.
Earthquake strength is measured on the judge’s scale or moment size. The judge scale ranges from 1 to 10, one is the weakest and 10 is the most powerful. Firering is a region around the Pacific Ocean, where many tectonic plates meet.
There are many earthquakes and volcanic eruptions in the area.
Other seismic attack areas include locations along the fault line, such as the rejection of San Andreas in California and the Himalayas region of Asia.
Below are some tips to keep you safe during an earthquake.
1. Fly, cover and hold on: Once inside the floor, fall onto the floor, cover under stable furniture and grab the stop.
2. Stay away from the window: glass may break during an earthquake. So stay away from windows and anything that can fall.
3. If you are outside, you can fall during an earthquake, so you will stay in open areas of buildings, trees and power lines.
4. After the earthquake: Beware of aftershocks and check for dangers such as gas leaks and collapsed power lines. The main cause of earthquakes is the movement of tectonic plates that collide, pull apart, or slide with each other. Earthquakes can shake the floor and sometimes damage buildings and streets. Scientists continue to look at earthquakes to better predict when and where they will occur, but it’s always important to be prepared if they do. earthquake.
There are three types of plate movement: convergence, divergence, and transformation. raw
