Introduction Earthquake Engineering can be defined as the branch of engineering devoted to mitigating earthquake hazards .In this broad sense‚ earthquake engineering covers the investigation and solution of the problems created by damaging earthquakes‚ and consequently the work involved in the practical application of these solutions‚ i.e. in planning‚ designing‚ constructing and managing earthquake-resistant structures and facilities In developing the Structural Engineering Slide Library as

EARTHQUAKES Introduction and Terminology • Vibrations in the earth’s crust that occur when strain in the crust is suddenly released by displacement along a fault line • Focus = point at which an earthquake originates inside the earth. May be many km below surface • Epicentre = the point on the earth’s surface directly above the focus. Strongest shock normally felt here. Most damage usually occurs here. • Seismology = the study of earthquakes – from Greek – seio – to shake

The largest earthquake ever occurred in the 20th century was the Valdivia Earthquake. As cited in the sources‚ the magnitude of this powerful earthquake was approximately 9.5 and totally destroyed communities near the epicenter. Because this great number of magnitude has a power to eradicate everything around it. Other earthquakes might be the larger but it’s the first one since accurate estimates of magnitude became possible. This was a megathrust earthquake which means that an earthquake occurred
