*Hello friend, I am back writing for some knowledge that I know from my reading. So, this foot I will write about the earthquake, for more details I will write about the Megathrust earthquake. As we know that some areas in this hemisphere often experience earthquakes and even tsunami disasters. This time I went back to discuss one of the earthquake phenomena that have occurred in some parts of the world.* *Earthquakes are not a negligible phenomenon, even earthquakes also often carry some great damage and effects to the area. This time I will invite you all to better understand about Megathrust earthquake, so that I and you know the information.* ![image](https://img.esteem.ws/dceqqwoxp5.jpg) [Source Image / Reference:](http://www.newstalkzb.co.nz/news/national/scientists-share-fears-of-megathrust-earthquake/#ath) *Understanding Megathrust, this earthquake is an earthquake that is one of the many earthquakes in the world. Megathrust itself is actually a nickname, a designation for a subduction area or location. This Megathrust is a condition like plate pushing other dishes. resulting in subduction and earthquakes. This causes one plate to move up and the other to move downwards.* *Because the Megathrust earthquake occurred on the plains near the earth and the shallow plate, the earthquake eventually had a very large scale or power. For the scale of the Megathrust earthquake can start from 8.0 SR to 9.0 SR. Even scientists also estimate that Megathrust could reach more severe than 9.0 SR which would mean the worst earthquake that will occur.* *Megathrust is one of the largest causes of earthquakes ever occurring around the world and could also be one of the causes of the Tsunami disaster that has been experienced in several countries in the world such as in Aceh and Japan.* *As we know if Megathrust is one of the many earthquakes that can cause severe earthquakes and tsunamis. If we ever know about Megathrust. Right now I'm going to tell you all about the Megathrust zone, so more about Megathrust is more specific.* ![image](https://img.esteem.ws/58n8iszhqd.jpg) [Source Image / Reference:](https://www.researchgate.net/figure/The-Sunda-megathrust-plate-boundary-along-which-the-2004-Sumatra-Andaman-and-2005_fig1_249873137) *For the Megathrust zone in Aceh to be in the Sunda Strait. This Megathrust Zone reaches a wide reach. This zone is often referred to as a subduction zone, the Sunda Strait is the zone responsible for large earthquakes and major tsunamis that occur worldwide. According to scientists, this Megathrust Zone is one of the most active zones in the world.* *Megathrust zone itself is divided into three zones, namely the Andaman Megathrust zone, Sumatra Megathrust zone, and Java Megathrust zone. This zone is very wide, has an area or range of more than 5,500 km, ranging from northern Myanmar to the direction of Sumatra, then can continue to the south, and ends in Australia. It is one of the meeting places of the Eurasian plate and is struck by the Indonesian plate to Australia.* *I have discussed the definition and character of Megathrust, now I will write some information about the characteristics of the earthquake, so it can understand it better. Before that also must know about the process of occurrence of volcanic earthquakes. So we have more knowledge about the earthquake. This time we will discuss about the giant character or so-called Megathrust.* ![image](https://img.esteem.ws/7lgocmc7vb.jpg) [Source Image / Reference:](http://www.dailymail.co.uk/news/article-3703378/Giant-megathrust-fault-discovered-Earth-s-crust-densely-populated-globe-wipe-tens-millions-earthquake.html) - **Large Earthquake Scale:** *Earthquake this one many scientists who call it as a giant, the giant itself is called because of this earthquake has the characteristics of having a large enough scale. Megathrust itself has a scale ranging from 8.0 SR to 9.0 SR, or more than that. Even Megathrust can also reach 10 SR. Is not that great on the Richter scale?* - **Potential Tsunami:** *The second characteristic of this one earthquake has the potential to cause a tsunami. As has been said by experts, if Megathrust is one of the most active zones in the world and is also responsible for the massive earthquakes and tsunamis. The large Ricther scale can cause some potential tsunamis.* - **Impact of Megathrust:** *Natural disasters like earthquakes. For example, always have consequences of earthquakes or other effects for the region experiencing them. Just like any other earthquake, if another earthquake impacts. Then so does Megathrust. Earthquakes that can reach up to 10 SR is even has some impact for the region or zone that experienced it. Because of that from now on we will also convey some impact Megathrust ever rocked several cities or countries in various parts of the world.* - **Abrasi On the Beach:** *The first impact of Megathrust is that it can damage the shoreline or can experience severe abrasion. As in the previous information, if Megathrust is large scale so it potentially damages many things one of them is with a severe abrasion on the beach. Especially if there is a tsunami caused by Megathrust. there will definitely be abrasion on the beach.* - **Building Roboh:** **Because this Megathrust earthquake is an earthquake with SR or large scale. One of the impacts of Megathrust is the severe damage to infrastructure and can also knock down large buildings. Some experts say, especially if skyscrapers or high-rise buildings have a bad structure that is not built specifically and the building has the potential to be tilted. and the damage occurred during the earthquake. Not only tilted, when Megathrust happens then large buildings that have the potential to collapse directly.* - **Infrastructure Damage:** *If Megathrust happens, there will be many impacts for us. One of them is the severe damage to the infrastructure, for example there will be cracks in the highway, the fall of several bridges and other infrastructure. Megathrust has a large impact of damage. So it would be nice if the infrastructure is planned carefully and well built, so that no major damage occurs.* - **Taking the Victims:** *The last impact that Megathrust can cause is that this earthquake can cause a lot of casualties. Given, this earthquake has a scale large enough and high enough that will cause many casualties. Not only are the victims injured, because Megathrust is quite dangerous and has a large scale, and sometimes difficult to predict. It can cost a lot of lives. In fact, this Megathrust once occurred in the Indian Ocean and caused a massive tsunami that killed thousands of people.* - **Megathrust phenomenon:** *From some of the information we mentioned above about Megathrust, we already know some information. Now I will show some phenomena of this great earthquake. I will give you some information about the Megathrust phenomenon that has occurred in various parts of the world, so you know what ever happened.* ![image](https://img.esteem.ws/8535yvvr0n.jpg) [Source Image / Reference:](https://uwaterloo.ca/wat-on-earth/news/tsunami) **Earthquake and Tsunami of Aceh in 2004.** *Do you still remember it? Tsunami that occurred in Aceh in 2004 ago has a large-scale earthquake, this is a tsunami and also a devastating earthquake that ever occurred in Aceh. The tsunami that occurred in Aceh was one of the main phenomena of the Megathrust earthquake.* *Tsunamis and devastating earthquakes are grouped into Megathrust, as they are within the Sunda Straits Subduction zone, to scale only when the earthquake occurs in the range of 9.1 SR to 9.3 SR. The earthquake that entered the Megathrust category is so large that it causes many lives to float. Hundreds of thousands of other victims suffered severe injuries and also minor injuries. During the day and night, Aceh is completely flattened.* **Earthquake and Tsunami Tohoku, Japan at 2011**. *This country also experienced tsunami and Megathrust disaster is terrible. The earthquake that occurred in Tohoku Japan is arguably the Megathrust category, because of its huge scale. This quake has a scale of 8.4 SR, initially and evolved into a 9.0 SR vibration. This huge earthquake was also accompanied by a tsunami as high as 10 meters.* *This natural phenomenon also claimed lives, about a dozen thousand people died, thousands suffered serious injuries and mild, and lost in some areas. Large earthquakes and tsunamis also affect some countries. Aceh, Tsunami as high as 1 meter and also some tsunamis or other waves in some countries of Asia and the west.* **Earthquake in Chile, in 2012.** *One example of the Megathrust phenomenon is the earthquake in Chile. A year after the big earthquake in Japan. Chile also experienced an earthquake that we call Megathrust. The earthquake* in Chile has a strength of about 8.2 SR to 8.8 SR. *For the earthquake that occurred in Chile it just took some casualties and some damage. Why? This is because the Chilean government implements the structure and level of the building, so that all houses and buildings are built strongly and when large quakes vibrate even though nothing will collapse badly.* *Well that's some information about the Megathrust earthquake that I can tell you, tulisa. this I quoted in some blogs and news on the internet. Hope this can add insight to me and you all.* https://s18.postimg.org/f14moi6ih/U5drca_Yp_Xvj1_C7f_RLKs_H7ps_Cs46_ZSZ7.gif *Thank you, this is my writing for this time, if there are words that are not good, not polite, not clear.
