Puerto Rico Natural Hazards | Peligros naturales de Puerto Rico
The island of Puerto Rico is subject to numerous threats from natural hazards, including hurricanes, landslides, earthquakes, tsunamis, coastal and inland flooding, environmental contaminants, and freshwater scarcity, among others. USGS science can help citizens better prepare for, mitigate, and adapt to these hazards. This website compiles USGS resources available for Puerto Rico to provide...
Puerto Rico Natural Hazards: Coastal | Peligros naturales de Puerto Rico: Costas
This page is a collection of USGS coastal hazard research in Puerto Rico, including shoreline changes, coral reef assessments, and coastal flooding. A brief description of highlighted projects can be found below. All coastal hazard publications, data releases, and news for Puerto Rico can be accessed on this page. Esta página es una recopilación de investigaciones del USGS sobre los riesgos...

USGS DUNEX Operations on the Outer Banks
DUring Nearshore Event eXperiment (DUNEX) is a multi-agency, academic, and non-governmental organization (NGO) collaborative community experiment designed to study nearshore coastal processes during storm events. The experiment began in 2019 and is scheduled for completion in the fall of 2021. USGS participation in DUNEX will contribute new measurements and models that will increase our...
Coastal Resource Evaluation for Management Application (CREMA)
Coastal environments are dynamic systems that provide high ecological, economical, recreational, and cultural value. Managing coastal systems requires a comprehensive understanding of the complex interactions between geological and ecological processes, as well as the ability to predict both the near-term and long-term impacts of storms and sea-level rise. The Coastal Resource Evaluation for...
Storm-Impact Scale
The potential vulnerability of a particular stretch of coast can be assessed using a conceptual model that scales the impacts of storms on barrier islands.
Coastal Change Hazards
Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative changes associated with coastal and marine processes, such as sea-level rise...
Real-Time Storm Response
Coastal change forecasts and pre- and post-storm photos documenting coastal change for landfalling storms. Currently responding to Hurricane Dorian.
Coastal System Change at Fire Island, New York
Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm waves...
Barrier Island Evolution - Applied Research
Assessments include depiction of trends (the past points to the future), updated observations (topography/bathymetry), and predicted sensitivity of barrier island evolution to possible climatologies and restoration plans.
Barrier Island Evolution - Geologic Analysis
Quantifying changes in morphology and sediment distribution over short time scales will demonstrate how geologic variability influences medium-term barrier island response and near-term barrier island trajectories and help to refine sedimentological boundary conditions for morphologic evolution models.
Barrier Island Evolution - Numerical Modeling and Oceanography
Numerical models compliment the collection of geophysical data by hindcasting and forecasting sediment transport pathways, natural island trajectories, and berm/island interactions over larger and higher resolution domains and time periods.
