Introduction to earthquakes quizzes february 26, 2017 leave a comment an earthquake (or quakes, tremors) is shaking of the surface of earth, caused by sudden movement in the earth's crust. In an earthquake, the initial movement that causes seismic vibrations occurs when two sides of a fault suddenly slide past each other a fault is a large fracture in rocks, across which the rocks have moved.

Structures of uniform response are special earthquake resistant frames in which members of similar groups such as beams, columns and braces of similar nature share the same demand-capacity ratios regardless of their location within the group the fundamental idea behind this presentation is that seismic structural response is largely a function of design and construction, rather than analysis.

Unfortunately, there has been relatively little research on the topic of economic effects of serious earthquakes by economists thus, the statements that can be made are based largely on extension of economic theory that has been developed to analyze effects of phenomena analogous to earthquakes.
