Figure 5. Example of the application of SMUG detailed rating criteria

Text Description of Figure:

Figure five shows the SMUG methodology in tabular form as applied to debris avalanche, lahars and associated flood in the Taranaki Region.

Overall the SMUG rating for this hazard is given as 13. This figure is the aggregated score across the four criteria (listed underneath the score) rounded to the nearest one.

The first criteria, seriousness is given an average score of 3.8. This average is derived from:

• Risk humans from drowning or being trapped are limited to one or two catchments, with a resulting risk score of four.
• Social risk is associated with long-term disruption, also with a score of four.
• Economically there are risks presented to bridges and the location of industry, a resulting score of four.
• The restricted geographic nature of the hazard means it has a score of three on this aspect.

Second, manageability is given an overall score of 4. Management difficulty is high due to the difficulty in predicting a path for the lahar. Current effort (awareness, planning, monitoring equipment placement and the like) is rated as medium.

Third, urgency is rated as three.

Finally growth in risk is rated as two. There is low probability of increased risk, while community exposure is rated as medium (due to increased development along channels and river banks).
