RELATION BETWEEN EARTHQUAKE MAGNITUDE AND ENERGY RELEASED An earthquake of magnitude 8.2 releases 1000 times more energy than the earthquake of magnitude of 6.2 and 32 times more than the magnitude of 7.2. A table below gives the relation between magnitude change and energy released during earthquake. Magnitude change Energy released 2.0 1000 times 1.0(…)

MAGNITUDE & INTENSITY OF EARTHQUAKE
The point on the fault where slip starts is the Focus or Hypocenter, and the point vertically above this on the surface of the Earth is the Epicenter (Figure 1). The depth of focus from the epicenter, called as Focal Depth, is an important parameter in determining the damaging potential of an earthquake. Most of(…)
