Earthquake Occurrence Process: Definition, Types and Causes of Occurrence
The Process of Occurring Earthquakes: Definition, Types and Causes of Occurrence – How is the process of an earthquake occurring? On this occasion About the knowledge.co.id will discuss it and of course the things that also cover it. Let's look at the discussion in the article below to understand it better.
Earthquake Occurrence Process: Definition, Types and Causes of Occurrence
An earthquake is a vibration or movement that occurs suddenly due to a sudden release of energy that occurs on the surface of the earth. The sudden release of energy causes seismic waves, which can be destructive on various things that stand on the surface of the earth, including buildings, trees, and others other.
Earthquakes are usually caused by the movement of the earth's crust (earth plates). The word earthquake is also used to describe the area where the earthquake occurred. Our earth, even though it is solid, is always in motion, and earthquakes occur when the pressure created by the movement is too great to be able to withstand it.
Various technologies that exist today cannot predict earthquakes, but their robustness can be measured using a seismometer. The most universal scale for measuring the strength of an earthquake is the Richter scale.
Earthquakes that have a Richter scale below 3 or near 3 generally cannot be felt, but if magnitude has reached 7 on the Richter scale determined the earthquake has the potential to cause serious devastation Really.
The level of destruction caused by an earthquake is not only due to its robustness, but is also measured by the size of the area affected by the earthquake. The depth of an earthquake that occurs on a surface of the earth can also affect performance destructive, the closer to the ground surface, the earthquake has the potential to be more destructive big.
Although there is no definite limit to how many optimal Richter scale earthquakes can occur, history records them the largest ever earthquakes were of magnitude up to 9 on the Richter scale, but no more than 10 on the scale Richter.
Causes of Earthquakes
The sudden release of energy above the earth's surface is the trigger for an earthquake. This energy release is caused by the movement of the earth's plates which creates a pressure.
If the pressure that occurs is getting higher and greater then the pressure will no longer be able to be held by the edges of the plates, and this is when an earthquake occurs. Earthquakes can also be caused by active volcanic activity, this earthquake occurs in tandem with the ongoing process of the volcano about to erupt.
Several other earthquakes can also occur as a result of human activity and are not caused by nature at all. An example is the accumulation of an enormous mass of water in a dam that had occurred in the African region, the country of Zambia.
There are also those caused by the injection or entry, as well as the extraction of fluids into or from the earth, such as which had occurred in the Rocky Mountains Arsenal associated with the existence of a thermal power plant earth.
Explosives that are detonated by humans can also cause earthquakes, for example testing of an explosive or the process of testing nuclear weapons. Indonesia is a country that is categorized as a country that is prone to earthquakes because of its location on the ring of fire world, and has active volcanoes and mountain ranges both on land and on the deep seabed Lots.
The Most Powerful Earthquake in Indonesia
The most devastating earthquake that ever occurred in Indonesia was the earthquake that hit the Aceh region, and parts of North Sumatra. This earthquake occurred on December 26, 2004. This earthquake had its epicenter in the Indian Ocean, and had a very large magnitude of 9.3 on the Richter scale.
The earthquake not only affected Indonesia, but also Thailand, Malaysia, India on the east coast, and up to Sri Lanka. It was reported that around hundreds of thousands of people died, tens of thousands of people disappeared, and hundreds of thousands of homes disappeared.
This powerful earthquake not only brought great damage, but also brought Tsunami waves which were also very powerful thus causing enormous levels of damage and material losses, as well as greater loss of life Again.
The tsunami waves that swept this area are estimated to be as high as nine meters, and this disaster is also classified as a disaster that caused the greatest death in human history.
The tsunami waves were so strong that they could be felt in areas of Africa such as Tanzania and Somalia. This earthquake was also the largest earthquake that has ever hit Indonesia in the modern era, and resulted in a very large number of fatalities.
The Process of Occurring Earthquakes Based on the Type
-
Tectonic Earthquakes
Tectonic activity causes the movement of continental and oceanic plates, interactions between these plates also produce many geological structures that move actively. Plate interaction that contributes a lot of power to become an earthquake is subduction, where one plate sinks under another plate.
This subduction is a plate movement where the two plates move closer to each other, the resulting vibration is the result of the friction of the two sides of the plates that infiltrate each other. This vibration will get bigger if there is something that is blocking it but then suddenly infiltrates it.
Volcanic Earthquake
Volcanic earthquakes are closely related to volcanic eruptions. Magma from the body of the volcano is held back by a lava plug formed by the previously frozen magma. It takes a lot of energy to penetrate the rock, when the energy is released and destroys the plug, vibrations are formed which we will feel as an earthquake.
Extraterrestrial Earthquakes
Extraterrestrial factors are the cause of earthquakes originating from outer space, when objects from outer space penetrate the earth's atmosphere and hitting the earth's crust, violent vibrations will occur as is the case when a meteor hits the earth some time ago.
Medium Factor
Earthquake waves can spread by propagating through the medium. When there is vibration on the earth, the medium that can be traversed is soil, rock and water. When earthquake waves propagate through the ground, the impact will be different from the waves traveling through rock.
This is because rocks are more compact than soil. The longer and farther the waves propagate, the energy will gradually shrink and disappear.
When waves pass through rock that is more compact, then the speed will decrease, otherwise if the waves passing through the ground composed of loose material, its speed will spread and destroy objects that are loose he passed.
Different things if the wave moves through the medium of water. These waves are usually generated by material avalanches in troughs, plate movements or faults, and sea volcanic eruptions.
These waves propagate at a very fast speed towards the mainland. When it gets to shallower areas, the speed of the waves will decrease, but the height of the waves will increase and can potentially form a tsunami.
Depth Factor
Another factor is the depth of the earthquake source, the deeper the source, the smaller the resulting impact because wave energy will run out when it spreads up, and vice versa.
Thus the review from About the knowledge.co.id about Earthquake Occurrence Process, hopefully can add to your insight and knowledge. Thank you for visiting and don't forget to read other articles.
