It is interested to understand that all of us would never want to experience earthquake plates disaster while on the other hand we unconsciously have gained so much information about it in our daily lives through so many advanced technology devices i.e. electronic gadgets and mass media. You want to believe that at some region with high risk of earthquake the resident want to have their own earthquake seismic monitor iris built. It is a too much request due to the fact how severe the damage an earthquake can make to a territory. You have seen the latest Japan Tsunami as well as Aceh’s. Nobody want to remember those massive disasters while indeed all of us stored that happening deep down in our memories. The question then turned into what are the causes and reasons for the earthquake?
Tectonic earthquake plates are the most plural earthquake disaster occurred throughout the history of mankind as a result of a great movement that occurred in the lining tectonics plate in lithosphere soil layers. A thin layer that covers the outer surface of the earth which you can say as earth’s outer skin. The prime cause of earthquake to occur are:
- Volcanic earthquakes: occurs due to an active volcano activity. You remember the term of “ring of fire” is the real meaning to define active volcanoes line along continents. So it is clearer now why there are areas with frequent earthquake which you can say to happen on regular basis. It is out of question why people want to live in those areas? Simply it is because they are meant to live there with its natural consequences plus many other reasons i.e. good yield of various products. Some people say in ring of fire areas you can expect to find good qualities of gemstones. This is basically true as up to now there are reports from people who find precious gemstones simply when they dig the soil when they are about to make a building foundation or for other purpose.
- Earthquake debris: avalanches or debris caused by the cave wall ruin inside the earth soil layers. Due to the rounded shape of the earth each layer of plates has potential to be broken or cracked at some borderline. These plates are in constant motion also the whole time and bumping one into another. The plate is then over millions of years of volcanic activity of the mountain and appear in it. Thus providing natural disaster threat volcanoes. Earthquake debris is the other side of the same coin to volcanic earthquake. That is to explain how it happens as sometimes people get confused between the two.
Tectonic earthquake plates: is an intens and severe vibration that occurs due to the earth’s shifting plates. Tectonis earthquake in the more current seismic design of structures and bridges is to design a structure that will achieve a specified deformed state. Under a specified design level earthquake rather than by ensuring the design forces are less than the specified material strength limit. By allowing some deformation that is within an acceptable amount at the design earthquake, the peak tectonic earthquake forces may be significantly reduced. The deformation allowed is usually limited to what is termed as repairable damage. Yet one want to bear in mind it is in huge scale of power and energy that we are dealing with. A repairable damage could mean a massive years of physical work to restore the damages caused by tectonic earthquake.
