WebWhile an earthquake has just one magnitude, its levels of intensity decrease with distance from the epicenter. The waves get smaller as they travel away from the fault. Think of a lightbulb: It has one wattage, but the brightness that energy produces decreases with distance as the light spreads out. Intensity also can vary depending on geology.

WebBy Earthquake Hazards 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. flag mount on columnWebNo, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other. canon 300mm f2.8 isWebMuch of the intensity data in the Earthquake Intensity Database for 1928-85 were taken from this annual report.
