Well, consider this; Haiti was devastated by a magnitude 8.9 earthquake. A magnitude 5 could either be worse, or better than that. It depends where the earthquake hits. If it strikes a overpopulated city, then the death toll and destruction would be high. If it hits a remote area, the quake could go unnoticed and unharmful.
A magnitude 6 earthquake has 10 ten times the energy of a magnitude 5 earthquake.
A magnitude 9 earthquake is 10,000x stronger than a magnitude 5.
The maximum ground motion of a magnitude 5 earthquake is 100 times larger than a magnitude 3 earthquake.
The Richter scale is not a linear scale. This means that an earthquake of magnitude 6 does not have twice as destructive power as the earthquake of magnitude 3. Actually, an earthquake with magnitude 5 is ten times more destructive than an earthquake of magnitude 4. The Richter scale is a logarithmic scale.
The Richter magniude scale is logorithmic. As such the size (amplitude) of the largest seismic waves produced by a magnitude 7 earthquake are 102 (or 100) times larger than those produced by a magnitude 5 earthquake. However the amount of energy released by a magnitude7 earthquake is 1000 times greater (102)^3/2 than a magnitude 5 earthquake and so it is likely to be much more destructive.
A magnitude 6 earthquake has 10 ten times the energy of a magnitude 5 earthquake.
A magnitude 9 earthquake is 10,000x stronger than a magnitude 5.
A magnitude 6 earthquake emits roughly 31 times more energy than a magnitude 5 earthquake. The magnitude 6 quake will also have a maximum seismic wave amplitude of ten times the magnitude 5 earthquake.
The maximum ground motion of a magnitude 5 earthquake is 100 times larger than a magnitude 3 earthquake.

That would be a "kind of strong" earthquake but 8+ is huge.
Because the "magnitude scale is not linear, it is logarithmic (its numbers are an order of magnitude apart) this mean that the a magnitude 6 earthquake is TEN TIMES more powerful than a magnitude 5 earthquake and a HUNDRED TIMES more powerful than a magnitude 4 earthquake.

30 times more energy released. 10 times more ground motion*

A magnitude 5 earthquake may cause slight damage to well designed buildings and major damage or destruction of poorly constructed buildings.
