Our earth of course happen to be a solid material. As solid thing, it should not have been movable. But within the earth actually materials have been moving all the time. This movement will cause energy and if result of movement is too big and even goes beyond its endurance limit, earthquake happens. There are some type of earthquake and one of them is called "Tectonic earthquake". It happens because of the act of releasing energy as result of friction of tectonic plates.
The energy yielded by collision among stones is known as "Tectonic Handicap". Theory of tectonic plates explains that earth consists of some stone layers which most of crust layers will drift and form a floating layers just like layers of ice. These layers which are broken into many pieces move slowly and then collide between one another. Power of spread of tectonic earthquake is different from other kinds of earthquakes because it follows meeting patterns of tectonic plates that compiles earth's crust.
Base on the above facts, we can conclude that when the earthquake happened, the most dangerous things are the buildings erected in the earthquake risky area not to mention people's awareness and the way they behave to the earthquake itself.
It is really touching and so sad to see the impact of earthquake that has happened in Indonesia. We should have realized that natural disaster actually is a warning from ALLAH SWT. His warning is to make people aware of not to be so arrogant to ALLAH SWT. Not to dare break his law either. Human should have protected the earth instead of ruining it because ALLAH SWT created this world including human and other creatures within is not without aims.....
Okay,. that's all, guys.. please give comment !!
