Introduction to Earthquake: An earthquake is a major demonstration of the power of the tectonic forces caused by endogenetic thermal conditions of the interior of. Smaller earthquakes, called foreshocks, may precede the main earthquake, and aftershocks may occur after the main earthquake.
Earthquakes are mainly confined to specific areas of the Earth known as seismic zones, which coincide mainly with ocean trenches, mid-ocean ridges, and mountain ranges.Download
