Intro Good morning everyone, Amitabha Good morning So, in this opportunity, I will explain about liquefaction So liquefaction is a phenomenon of liquid or liquid soil that contains high water So the soil is not dense, so there is a movement So it does not have the strength to withstand the rotation of the earth like a building So as you can see here, there are three conditions The first is when it erupts And the second is when the soil around the liquefaction area is dense and sand-like So the sand-like soil becomes mud So the mud does not have the strength to withstand the rotation of the earth So the area around the liquefaction area is usually in the sea, beach, and areas where the soil contains high water Because it is sand-like And the actual example is on September 28, 2018 There was an earthquake in Central Sulawesi This area is more popularly known as Palu earthquake And more specifically in Petobo So coincidentally in Petobo, there is a river around it And at the same time near the beach And the two types of soil that are in the liquefaction area, as I have mentioned The first is the soil that does not have the strength to withstand the rotation of the earth like sand And the second is the soil that contains high water So it contains high water And the impact of the earthquake is First, the soil moves, especially the houses and buildings So the houses and buildings are usually mixed with the mud And the second is the soil surface becomes lower And makes a difference in the surface So there are some that are high and some that are low And the mitigation steps or the trial steps can do in-depth research Such as checking the structure of the soil when planning an earthquake So that the construction of young soil that is prone to liquefaction can be prevented So before I end this presentation The words today are Between the map and the compass, we find a way to understand the world Thank you
