From my analysis of GM Hazard, the GM earns Hazard by:

1. Rolling the Adversity dice for the world being explored at the start of the adventure
2. In Conflict between players and specific GMC's, in a similar fashion to the way players earn Fortune (i.e. roll eliminated dice, odd give a Hazard point).
3. Every point of Fortune spent by a player nets the GM a point of Hazard.
