In many of the lesser developed areas of the world, regional development planning is increasingly important for meeting the needs of current and future inhabitants. Illustrates how matrix assessment methodology was applied to produce a landslide-susceptibility map for the Commonwealth of Dominica, an island nation in the eastern Caribbean, and how with a follow up study the relative landslide-susceptibility mapping was validated. A second Caribbean application on Jamaica demonstrates how this methodology can be applied in a more geologically complex setting.
A benefit-cost analysis was performed on varying levels of standard buildings codes for Haiti and Puerto Rico. It was found that in the two areas studied, the expected loss of life was reduced the most by use of high seismic building code levels, but lower levels of seismic building code were more cost-effective when considering only building damages and the costs for code implementation.
