The high concentration of KMA active landslides within 90m of roads is very similar to that described by Larsen and Parks (1997) for shallow landslides [50 years old] in Puerto Rico.
In Puerto Rico, Larsen and Parks (1997) found that landsliding densities within 85m of the road were 8 times higher than beyond that distance.
In the incised valley of the Wagwater River both small active landslides and larger scarps-definite and scarps-probable are mapped.
Most of the active landslides are probably road related, but some of the larger scarps may be natural failures on the steep valley walls.
Landslides are concentrated along the road from Stony Hill to Mount Airy and to Mount Telegraph on the St. Andrew-Portland divide.
Similar landslides occur on the roads leading to Woodford, in the valley of the Hope River, and along the roads north and east of Gordon Town.
· IT APPEARS THAT MOST OF THESE SMALL ACTIVE LANDSLIDES AND SLIDE ZONES ARE HUMAN-INDUCED.
