Hurricane Maria | Huracán María
In September 2017, Hurricane Maria made landfall in the Caribbean as a category 4 storm. Based on a Federal Emergency Management Agency (FEMA) 2018 report (FEMA P-2020, 2018), it caused $90 billion in damages, mostly in Puerto Rico. Hurricane Maria was the third costliest hurricane ever recorded in the United States. In Puerto Rico, more than fifty thousand houses were reported as visually affected or destroyed by the hurricane. Critical infrastructures were damaged and interrupted for months, including the water supply, electric network, telecommunications, transportation, roads, and healthcare. The image below shows the tracks of Hurricane Maria. USGS scientists have investigated the aftermath of hurricane Maria and other hurricanes such as Hugo (1989), Georges (1998), and Irma (2017). Learn more about these projects in the sections below.
En septiembre de 2017, el huracán María azotó el Caribe como una tormenta de categoría 4. En base al informe de 2018 de la Agencia Federal para el Manejo de Emergencia (FEMA P-2020, 2018), provocó daños por 90,000 millones de dólares, principalmente en Puerto Rico. El huracán María fue el tercer huracán más costoso registrado en los Estados Unidos. En Puerto Rico, se reportaron más de 50 mil casas que fueron destruidas o afectadas por el huracán. Luego del huracán, la infraestructura crítica se vio dañada o interrumpida por meses, incluyendo el suministro de agua, la red energética, las telecomunicaciones, el transporte, los caminos y la atención sanitaria. La próxima imagen muestra la trayectoria del huracán María. Los científicos del USGS han investigado las consecuencias de éste y otros huracanes como Hugo (1989), Georges (1998) e Irma (2017).

Hurricane Maria Landslides | Los deslizamientos de tierra causados por el Huracán María
Hurricane Maria triggered over seventy thousand landslides in Puerto Rico, affecting critical infrastructure across the island, disrupting roads and dislodging houses from their foundations. An interactive landslide susceptibility map for Puerto Rico can be accessed here. USGS collaborated with federal and academic partners to produce materials describing landslide risk to better support residents and facilitate information dissemination to emergency managers. A landslide guide was created in Spanish and English that can be accessed via the Puerto Rico Landslide Hazard Mitigation Project page.
El huracán María desencadenó más de 70,000 deslizamientos de tierra en Puerto Rico, los que afectaron la infraestructura crítica en toda la isla, interrumpiendo las vías de trasportación y desplazando casas de sus cimientos. Se puede acceder al mapa interactivo de susceptibilidad a los deslizamientos de tierra para Puerto Rico aquí. El USGS colaboró con socios federales y académicos para proporcionar materiales que describan el riesgo de deslizamiento de tierra para asistir mejor a los residentes y facilitar la divulgación de información entre los manejadores de emergencias. Se creó una guía sobre los deslizamientos de tierra en español y en inglés que se encuentra en la página del Proyecto para la Mitigación de Riesgos por Deslizamiento de Tierra.
Storm Surges and Floods | Las marejadas y las inundaciones
USGS collaborated with the Federal Emergency Management Agency (FEMA) in installing temporary stations with water-level and barometric pressure sensors prior to Hurricane Maria to measure coastal and riverine high-water marks throughout Puerto Rico during the storm. In addition to the temporary sensors, USGS has a network of 99 permanent real-time stream gages and 36 real-time precipitation stations in Puerto Rico. Access the report about the effects of Hurricane Maria, developed to assess flooding, storm tides, and precipitation.

Coastal Flood Risk Increase Due to Hurricane-Induced Coral Reef Damage | El aumento del riesgo de inundación costera debido a los daños en los arrecifes de coral provocados por huracanes
Hurricanes Irma and Maria caused a significant increase in risk of future coastal flooding due to coral reef damages. The fringing coral reefs surrounding the coastline of Puerto Rico are the first line of flood defense from coastal hazards. The repercussions of reef damage in Puerto Rico were assessed with high resolution hydrodynamic and socioeconomic models. In Puerto Rico, it was estimated that the cost of future flood damages could increase due to reef damage by $178 million annually (visit report). However, reef restoration could potentially avert over $40 million in economic damages per year (visit report).
Los huracanes Irma y María causaron un aumento importante en el riesgo de inundaciones costeras futuras debido a los daños de los arrecifes de coral, que son la primera línea de defensa contra los riesgos costeros. Las repercusiones de los daños de los arrecifes de coral en Puerto Rico fueron evaluadas con modelos socioeconómicos e hidrodinámicos de alta resolución. En Puerto Rico, se estimó que el costo de los daños de inundaciones futuras debido a daños en los arrecifes de coral podría aumentar 178 millones de dólares por año (consulte el informe). Sin embargo, la restauración de los arrecifes podría evitar más de 40 millones de dólares en daños económicos por año (consulte el informe).

Coastal Flood Risk Increase Due to Hurricane-Induced Coral Reef Damage | El aumento del riesgo de inundación costera debido a los daños en los arrecifes de coral provocados por huracanes
Hurricanes Irma and Maria caused a significant increase in risk of future coastal flooding due to coral reef damages. The fringing coral reefs surrounding the coastline of Puerto Rico are the first line of flood defense from coastal hazards. The repercussions of reef damage in Puerto Rico were assessed with high resolution hydrodynamic and socioeconomic models. In Puerto Rico, it was estimated that the cost of future flood damages could increase due to reef damage by $178 million annually (visit report). However, reef restoration could potentially avert over $40 million in economic damages per year (visit report).
Los huracanes Irma y María causaron un aumento importante en el riesgo de inundaciones costeras futuras debido a los daños de los arrecifes de coral, que son la primera línea de defensa contra los riesgos costeros. Las repercusiones de los daños de los arrecifes de coral en Puerto Rico fueron evaluadas con modelos socioeconómicos e hidrodinámicos de alta resolución. En Puerto Rico, se estimó que el costo de los daños de inundaciones futuras debido a daños en los arrecifes de coral podría aumentar 178 millones de dólares por año (consulte el informe). Sin embargo, la restauración de los arrecifes podría evitar más de 40 millones de dólares en daños económicos por año (consulte el informe).

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards. In the United States, the physical protective services provided by coral reefs were recently assessed in social and economic terms, with the annual protection provided by U.S. coral reefs off the coasts of the State of Florida and the...

Tropical forests are expected to experience unprecedented warming and increases in hurricane disturbances in the coming decades; yet, our understanding of how these productive systems, especially their belowground component, will respond to the combined effects of varied environmental changes remains empirically limited. Here we evaluated the responses of root dynamics (production...

The effects of runoff from land on nearshore ecosystems, including coral reef communities, are influenced by both sediment supply and removal by coastal processes. Integrated studies across the land-sea interface describing sources and transport of terrestrial sediment and its nearshore fate allow reef protection initiatives to target key onshore and offshore areas. Geochemical...

Insights on impacts and resiliency of avian species with respect to hurricanes in the Caribbean have largely focused on responses measured in protected habitats. We assessed avian responses in non-protected habitat, specifically shade-restored coffee plantations, because their structural complexity retains many attributes of secondary forests, and may contribute to landscape scale...

Mountain ranges generate clouds, precipitation, and perennial streamflow for water supplies, but the role of forest cover in mountain hydrometeorology and cloud formation is not well understood. In the Luquillo Experimental Forest of Puerto Rico, mountains are immersed in clouds nightly, providing a steady precipitation source to support the tropical forest ecosystems and human uses. A...

The devastating impacts of the widespread flooding and landsliding in Puerto Rico following the September 2017 landfall of Hurricane Maria highlight the increasingly extreme atmospheric disturbances and enhanced hazard potential in mountainous humid‐tropical climate zones. Long‐standing conceptual models for hydrologically driven hazards in Puerto Rico posit that hillslope soils remain...

The effects of climate change on tropical forests may have global consequences due to the forests’ high biodiversity and major role in the global carbon cycle. In this study, we document the effects of experimental warming on the abundance and composition of a tropical forest floor herbaceous plant community in the Luquillo Experimental Forest, Puerto Rico. This study was conducted...

Mobility is an important element of landslide hazard and risk assessments yet has been seldom studied for shallow landslides and debris flows in tropical environments. In September 2017, Hurricane Maria triggered > 70,000 landslides across Puerto Rico. Using aerial imagery and a lidar digital elevation model (DEM), we mapped and characterized the mobility of debris slides and flows in...

Tropical forests represent 50% of the planets species and play a disproportionately large role in determining climate due to the vast amounts of carbon they store and exchange with the atmosphere. Currently, disturbance patterns in tropical ecosystems are changing due to factors such as increased land use pressure and an occurrence of hurricanes. At the same time, these regions are...

On September 20, 2017, Hurricane Maria triggered widespread debris flows in Puerto Rico. We used field observations and pre- and post-Maria lidar to study the volumetric growth of long-travelled (>400 m) debris flows in four basins. We found overall growth rates that ranged from 0.7 to 30.4 m3 per meter of channel length. We partitioned the rates into two growth mechanisms, aggregation...

Hurricane Maria made landfall south of Yabucoa Harbor, Puerto Rico, as a category 4 hurricane with maximum sustained winds of 155 miles per hour on September 20, 2017. The hurricane devastated much of the U.S. Virgin Islands and Puerto Rico. The U.S. Geological Survey (USGS), in cooperation with Federal Emergency Management Agency, installed a temporary monitoring network of 13 water...
Hurricane Maria made landfall in Puerto Rico on September 20, 2017, bringing with it a mix of high winds and extreme rainfall. This data visualization animates Hurricane Maria's Water Footprint, the cumulative precipitation the storm dropped on the island, and the impact of rainfall on river gage height.
