Earthquake magnitude levels.

Ground shaking can be caused in various ways (volcanic tremors, avalanches, large explosions, etc.), but shaking intense enough to cause damage is usually due to rupturing of the Earth's crust known as earthquakes. The intensity of shaking depends on several factors: The "size" or strength of the source … See moreHowever, the earthquake hazards are not determined by their magnitude alone, and moderate earthquakes may also cause severe disasters under specific circumstances, e.g., the 1994 M w 6.7 ...Magnitude Types; Magnitude Type Magnitude Range Distance Range Equation Comments; Mww (Moment W-phase)(generic notation Mw) ~5.0 and larger: 1 - 90 degrees: M W = 2/3 * (log 10 (M O) - 16.1), where M O is the seismic moment.

For example, a 5.5 is a moderate earthquake, and a 6.5 is a strong earthquake. Because the scale is logarithmically based, each whole number increase in magnitude represents a tenfold increase .While 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.
