Earthquake
Earthquakes are vibrations or shocks that occur due to the movement of layers of rock originating from the bottom or subsurface of the earth. Natural events that often occur in areas close to volcanoes and also in areas surrounded by vast oceans.
The earthquake occurred because of the shifting of the earth's lower layers and the terrible volcanic eruption. Earthquake events occur so fast with such a great impact and the effects it has are very extraordinary. Earthquake vibrations are very strong and spread in all directions so that it can destroy buildings and cause casualties.
Based on the cause of the occurrence, earthquakes can be classified into two, namely tectonic earthquakes and volcanic earthquakes. Tectonic earthquakes occur because the layer of the earth's crust becomes precarious or soft so that it experiences movement. "Tectonic Plate" theory contains an explanation that our earth consists of several layers of rock. Most of the crustal area will be washed away and float in layers, like snow. This layer moves so slowly that it breaks and collides with one another, which is why earthquakes occur.
Meanwhile, volcanic earthquakes occur because of an extremely devastating volcanic eruption. So that the ground around the mountain trembled and even vibrated until it felt far, it was the cause of volcanic earthquakes. This volcanic earthquake is less common when compared to tectonic earthquakes.
In concluded that the earthquake can occur at any time, without knowing the season. However, earthquake concentrations tend to occur in certain places, such as the Pacific Plate boundary. This place is known for its ring of fire because of the many volcanoes.
what can we do if earthquake is happening?

BalasHapusIf an earthquake occurs and you are inside the building immediately get out, once outside beware of tall buildings and trees.
Stay away from tall buildings and pillars
