[Qgis-user] different buffer for the same field

In the processing Toolbox there is a tool called Variable Distance Buffer.

If you add a field to your data giving each type a width (field called 
bufferwidth and it is 10, 20, 30 , 40 meters for each type) - you can 
use that tool to automatically buffer each fault accordingly.

Good Luck!
