The Hypocenter is the starting point of the earthquake and is defined by geographical coordinates and depth. The Epicenter is the projection of the hypocenter of the Earth’s surface and is defined by geographical coordinates.
Earthquake rupture area
When stress within the medium exceeds the strength of the material, it breaks ruptures. The area of destruction is called a rupture area. Rupture almost always occurs in weak and old areas (faults). A fault is a discontinuity in the integrity of the Earth’s crust, on which significant movements have taken place. In strong earthquakes, the rupture in the fault can be several hundred kilometers in length and tens of kilometers in depth. The size of the area that is torn by an earthquake increases with its intensity.
