The Blue Mountains in eastern Jamaica could be a region where landslides occur with heavy rain due to steep hill slopes, said Karl Lang, an assistant professor of geology at the Georgia Institute of Technology.

Lang said regions that have been clearcut for agriculture could be susceptible to landslides because the plants that previously grew there helped bind the soil together by the strength of their roots.

Some roads built on steep hills in Puerto Rico were affected by landslides when Hurricane Fiona (2022) and Hurricane Maria (2017) hit, said Lang. “Every time you cut into a steep slope, you make a steeper slope above the road,” he said.

“The real problem there is that you create the road that’s your conduit in and out of the location … and then the landslide dams the road. You create your own problem both by creating the increased probability of a landslide, but also by having those landslides occur where you need to go,” said Lang.
