The magnitude scale is logarithmic, so a 7 is 10x the power of a 6 and an 8 is 10x the power of a 7. That means it would take a thousand 5.0 quakes to dissipate a pending 8.0.
Hold on to your butts.
The magnitude is also one of about a hundred variables that can affect how bad an earthquake is. How deep in the earth it originates, the kind of rock and soil, epicenter location, etc., all change the equation a bit. Most people barely feel anything below about a 5.0, but if say a 5.5 originates close to the surface and affects an area with loose soil, it'll probably do a whole lot more damage and be more intense than a 6.5 in rockier terrain that better absorbs the energy.
