Earthquake Resistance TechniquesIntroduction“Earthquakes do not have the ability to kill or cause damage, unlike buildings.” This is a famous quote that tries to highlight the need for earthquake precautions and measures especially in buildings. Earthquakes, just like other natural disasters, cannot be prevented, although it is possible to minimize their impacts and effects. Like other natural disasters, earthquakes have the ability to cause damage to both life and property. Two basic types of seismic waves are responsible for causing earthquakes (Chang and Soong, 1992). These two waves are distinguished by the speed with which each of them travels through the earth. Primary or thrust waves travel faster and are longitudinal in nature. These waves have the ability to pass even through liquids. The slower waves are called secondary waves or shaking waves. These waves travel like light waves, although they cannot travel in liquids. Seismic waves that cause earthquake risks become more destructive as they travel through the ground and reach its surface where there are structures and buildings. When these waves reach such places, the cause is strong ground movement which causes buildings and structures to move and move at very high speeds. Most buildings and structures are unable to resist ground movements, and as a result, building and bridge collapses, fires, flash floods, and colorful destructive ocean waves occur, and in some cases, landslides occur. Densely populated areas can suffer serious injuries and deaths from earthquakes. To take precautions especially in buildings, it is necessary to implement various anti-seismic techniques.
