# How to predict Earthquake

Earthquake is a violent and sudden shock of the earth, which is often caused by two layers of the ground slipping from one another. Earthquakes are measured in accordance with their magnitudes. The earthquakes with higher magnitudes have higher destruction levels. Scientists believe that earthquakes can occur anywhere, anytime, and are unpredictable. Although the engineering society believes there are systems that can reduce the magnitude of the earthquakes, but in earthquake analysis of Structure by Base Isolation Technique, SAP T. Subramani. J., Jothi, M., and Kavithadiscusses base isolation structures and their various types. This article claims that the base-isolated structure is one of the most effective techniques in engineering that protect the building structure against the earthquake. The base-isolated structure is not a recent development and was created by engineers and scientist in1923. Countries like the U.S, Japan, andChina and European countries have used this structure in both their public and residential buildings since its creation.

The base isolation system is used to protect buildings from earthquake damage. Subramani et al. State that ‘’many significant advantages can be drawn from buildings provided with seismic isolation’’ (302). Base isolators are located at the basement level of the building to reduce the earthquake vibration and enable building structures to resist earthquakes. The logic behind this is that when a building structure is built on flexible bearings or pads and away from the ground. It will only move little or not at all. In addition, base isolated buildings cost 15%lower than building with the traditional structure for the same earthquake conditions. Base isolation can be installed into both new and old buildings. Base isolators are of various types.

The Seismic isolation system is an effective way to reduce the earthquake pressure. According to the authors, ‘’sliding bearings: for large vibrations, sliding materials slide to provide the same deformation performance as large-scale isolation systems.’’(303). the sliding tool, which is also known as the sliding bearing is a common type of base isolation system. This type of base isolator is designed to control and lower down high-level motions. A slide bearing has an upper and a lower part. The upper levels connected to the deck or the movable part of the structure (deck), and the lower level is attached to the structure part that is not movable. This type of base isolator can be placed in both bridges and buildings. Japan is one of the countries that use this method widely.

Base isolation is an engineering discovery which is used to avert or decrease earthquake damages. Subramanian al writes, that ‘’LRBis maintained during repeated strong earthquakes ‘’. (303) Lead rubber bearing or, (LRB)is another common type Base isolators. LRB is made of a laminated rubber, steel bearing and flat steel plates. The rubber bearing works as a spring. LRB is constructed to retain structure safety during repeated and powerful earthquakes.

The importance of base isolators is immeasurable, starting from the performance of a fixed based building compared to that with base isolators; the buildings with base isolators are better. The base isolators would be very important if put in place in public places, hospitals, and police stations. The number of lives to be saved in an earthquake is incomputable. The base isolators are crucial since they lengthen the vibration periods, in turn, and decreases the force response, which means they minimize the effects the earthquakes would have on the buildings and anything in it. It is also important for engineers to use sliding bearings since they are weather resistant and are durable. That means, there is a reduction in costs as compared to using other types of base isolators. This highlights that future research should focus on testing base isolation systems on hill, mountains, jungles and other environments in order to further outline the efficiency that this system provides.
