⏭️Earthquakes: introduction. An earthquake is a trembling or a shaking movement of the ground, caused by the slippage or rupture of a fault within the Earth's crust. A sudden slippage or rupture along a fault line results in an abrupt release of elastic energy stored in rocks that are subjected to great strain.

⏭️Earthquakes represent one of the largest potential source of casualties and damage for inhabited areas due to a natural hazard. Throughout history, they have destroyed countless cities and villages around the world and caused the death of thousands of people.

⏭️As well as the threat that earthquakes pose to life and property, the economic threat is also very significant.

⏭️Earthquakes are one of the most powerful forces to which civil structures will be subjected, and designing structures to resist these forces represents an economic burden. At the same time, failing to design structures against these forces can bring serious economic consequences in the event of a strong earthquake.

⏭️However, on average, strong earthquakes in earthquake prone regions only occur once every 50-100 years. Thus the probability that any given structure will be affected by a major earthquake during its lifetime is extremely low.

⏭️So, modern societies are faced with the challenge of deciding what is the optimum investment to protect against a hazard which is capable of causing great economic loss but which may not occur.
