Use generic, nonspecif-ic (non-ornamented) fault symbols when ori-entation or sense of slip is not known or not specified; use also on small-scale maps to show regional fault pat-terns.
This hazard map is the combination of results computed using 30 hazard input models covering the vast majority of landmass. These models represent the best information publicly accessible, and the GEM Foundation recognises their credibility and authoritativeness.
Where geologists have been able to interpret the type of fault, additional symbols may be used to indicate if it is a thrust fault, a high-angle fault (normal or reverse), or even a strike-slip fault (usually shown with arrows on either side of the fault).
