Earthquake Facts and Statistics
How Earthquakes Work
The Modified Mercalli Intensity Scale
“The effect of an earthquake on the Earth’s surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally – total destruction.”
