USGS staff are connecting with natural hazards researchers based in the Caribbean and those specializing in the region to find out which natural hazards are of primary concern, learn about their mitigation efforts, and explore the potential for research collaboration.
A Region Vulnerable to Hazards
Many Caribbean countries and U.S. Caribbean territories have been severely impacted by natural hazards such as hurricanes, earthquakes, and landslides. These hazardous events can exacerbate preexisting vulnerabilities such as health risks (e.g., contaminated water supplies), and conditions are expected to worsen with climate change. Some natural hazards impacting these small islands are driven by regional-scale processes that are linked to those of neighboring countries. Collaborative investigations on regional-scale hazards such as coastal storms, flooding, sea level rise, freshwater scarcity, earthquakes, droughts, and coral reef degradation will help us to better understand these physical processes and develop more accurate numerical models to predict their impacts, which could reduce loss of life and property.
USGS Natural Hazards Research in the Caribbean
Building Relationships to Enhance Natural Hazards Science

As part of the Stakeholder Engagement for Natural Hazards Investigations in the Caribbean (SENHIC) project, the USGS team aims to:
- Connect with scientists who are conducting, or have conducted, natural hazards research in the Caribbean;
- Build relationships with local experts in Caribbean countries and U.S. territories to learn about natural hazards of primary concern, mitigation efforts, and areas of overlapping interest;
- Construct a database of local experts to lay the groundwork for future collaborations;
- Inventory and create a list of regional natural hazard resources;
- Develop a framework for collaborating with international partners on natural hazards research in the Caribbean; and
- Document engagement strategies, best practices, key takeaways, and lessons learned.

The SENHIC project is jointly funded by the USGS Risk Community of Practice and the U.S. Agency for International Development (USAID) Bureau for Humanitarian Assistance. It is being led by Dr. Donya Frank-Gilchrist and Dr. Legna Torres-García of the USGS St. Petersburg Coastal and Marine Science Center. The team intends for this project to lay the foundation for future collaborations and information exchange to build resilience across the Caribbean region.

USGS staff are connecting with natural hazards researchers based in the Caribbean and those specializing in the region to find out which natural hazards are of primary concern, learn about their mitigation efforts, and explore the potential for research collaboration.
A Region Vulnerable to Hazards
Many Caribbean countries and U.S. Caribbean territories have been severely impacted by natural hazards such as hurricanes, earthquakes, and landslides. These hazardous events can exacerbate preexisting vulnerabilities such as health risks (e.g., contaminated water supplies), and conditions are expected to worsen with climate change.

USGS Natural Hazards Research in the Caribbean
USGS conducts natural hazards research in numerous Caribbean countries and U.S. territories on topics such as earthquakes, landslides, hurricanes, coastal erosion, and more. As part of the Stakeholder Engagement for Natural Hazards Investigations in the Caribbean (SENHIC) project, we are working to improve collaboration and consolidate information from these initiatives in order to make USGS science more accessible for stakeholders. Countries with colored dots indicate where current or past USGS natural hazards projects have been identified as of January 2023. View a larger map.

The USGS monitors and studies water resources to deliver a wide range of data including streamflow conditions, groundwater information, lake and reservoir elevation, water quality, water use, and water availability, which can be accessed through the USGS National Water Dashboard. As of 2022, the USGS real-time water data network is comprised of 109 streamflow observation stations, 20 groundwater...Puerto Rico Natural Hazards: Tsunamis | Peligros naturales de Puerto Rico: Maremotos
Tsunamis are long waves formed from a sudden displacement of the sea floor due to a fault rupture, landslide, or volcanic activity. Given that Puerto Rico lies above a subduction zone in the Caribbean Sea, it is especially susceptible to large earthquakes and tsunamis. The greatest tsunami ever recorded in Puerto Rico occurred from an earthquake off the Mona Passage in 1918. The USGS Earthquake...Puerto Rico Natural Hazards: Landslides | Peligros naturales de Puerto Rico: Deslizamientos de tierra
The Landslide Hazards Program from USGS works to help reduce the impact of landslides to people and infrastructure by furthering our understanding of causes of ground failure and by recommending strategies for risk mitigation. In Puerto Rico, USGS researchers have rigorously studied rainfall-induced landslides to provide maps that depict landslide susceptibility. Educational materials that...Puerto Rico Natural Hazards: Hurricanes | Peligros naturales de Puerto Rico: Huracanes
Hurricanes are one of the most frequent natural hazards that Caribbean islands are prone to encounter. The frequency of storms and their intensity could increase with climate change. This page contains a variety of USGS research on hurricane impacts to Puerto Rico, dating back to 1989, when Hurricane Hugo impacted the island. Research topics include storm-induced landslides, as well as impacts on...Puerto Rico Natural Hazards: Ecosystems and Environmental Contaminants | Peligros naturales de Puerto Rico: Ecosistemas y contaminantes ambientales
USGS researchers have studied environmental contaminants and pathogens to address questions involving exposure pathways and human-health implications. They also study climate change impacts and ecosystem health. On this page, read about ecosystems and environmental health research in Puerto Rico, including contaminants in tap water, and possible human exposures. Investigadores del USGS han...Puerto Rico Natural Hazards: Earthquakes | Peligros naturales de Puerto Rico: Terremotos
USGS provides real-time earthquake data, information on historic earthquakes, resources for the most significant earthquakes, and seismicity and ground motions to support future updates to the seismic hazard models for Puerto Rico and the U.S. Virgin Islands. Our seismic research can help establish better building regulations that mitigate earthquake risks and improve public safety. The USGS...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.
