Earthquakes: Definition, Causes, Measures and Other.
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. This energy can be built up and stored over a long time and then released in seconds.

In increasingly more earthquake-resistant buildings, designers are installing damping systems. Active mass damping, for example, relies on a heavy mass mounted to the top of a building and connected to viscous dampers that act like shock absorbers. When the building begins to oscillate, the mass moves in the opposite direction, which reduces the amplitude of mechanical vibrations. It's also.
When an earthquake strikes, as it did in Athens on 19 July, it can cause disruption for weeks and months afterwards. But how much do we know about earthquakes and what causes them? Any explanation.
Earthquake-resistant construction requires that the building be properly grounded and connected through its foundation to the earth. Building on loose sands or clays is to be avoided, since those surfaces can cause excessive movement and nonuniform stresses to develop during an earthquake. Furthermore, if the foundation is too shallow, it will deteriorate, and the structure will be less able.
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air, and wreak destruction across entire cities. The.
The Great Chilean Earthquake An earthquake is the shaking of the earth by seismic waves radiating away from the disturbance, most commonly fault movement. The great Chilean earthquakes origin was of the coast of Chile at a subduction zone, referred to as a hot spot for seismic activity. A subduction zone is a region on the crust of the earth where two tectonics plate meet one another. The area.
