Description :
The Blanco, Cibuco, and Coamo study areas were selected to evaluate the frequency and distribution of landslides in Puerto Rico. Maps of recent landslides developed from 1:20,000-scale aerial photographs, in combination with a computerized geographic information system, were used to evaluate the frequency and distribution of shallow landslides in these areas. Several types of landslides were documented : rainfall triggered debris flows, shallow soils slips, and slumps. A set of simplified matrices representing geographic conditions in the three study areas was developed and provides a basis for the estimation of the spatial controls on the frequency of landslides in Puerto Rico.
