Dams: The build-up of pressure due to the storage of a large amount of water in the reservoirs behind large dams is considered to be a potential cause of earthquakes. 2. Natural cause: Earthquakes are the result of slow-moving processes that operate within Earth. Tectonic earthquakes causes more damage than non-tectonic ones. An S wave is slower than a P wave and can only move through solid rock. This causes building to sink and may cause landslides.

The primary cause of an earthquake is faults on the crust of the earth. An earthquake is caused by a sudden slip on a fault. Where the crust is being compressed, reverse faulting occurs, in which the hanging-wall block moves up and over the footwall block – reverse slip on a gently inclined plane is referred to as thrust faulting.

Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth. • Causes of earthquakes This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps, which show instrumentally determined epicentres. Tectonic activity • Stresses are caused by convection currents in the asthenosphere • Diverging convection currents in the asthenosphere caused by tensional forces in rifts (normal faults) • Converging convection currents in the asthenosphere – Sima to Sima (Oceanic to Oceanic plates) • Creating 9.0 earthquakes on the Richter scale • Convection currents in the asthenosphere – Sial to Sial … Clipping is a handy way to collect important slides you want to go back to later. 2.
