Corina Cerovski-Darriau

Corina leads the USGS-USAID Landslide Disaster Assistance Team (LDAT), which collaborates with international partners on landslide hazard projects. Her expertise is remote and field mapping of surface processes, monitoring hydrologic change and sediment transport, and modeling landslide hazards.

As the USGS-USAID Landslides Hazards Advisor and Landslide Disaster Assistance Team (LDAT) manager, Corina oversees a variety of international educational and technical capacity building projects as part of a joint USGS and USAID Bureau for Humanitarian Assistance program. These projects work closely with in-country counterparts to support landslide mapping and monitoring efforts. Corina’s focus is capacity building to assess landslide hazards and create landslide awareness in order to prepare for future landslide events, and acting as a liaison between USGS and USAID. 

Her past research covered various topics in hillslope geomorphology – from producing geomorphic process maps to identify and quantify sediment erosion sources, to monitoring how long wildfire impacts soil hydraulic conductivity post-fire, to conducting landslide hazard assessment through field and remote mapping, to sampling and dating material properties to understand landscape evolution. Her scientific interest is the interaction of longer-term geomorphic processes on short-term hazards.

Landslide Inventory for Chuuk, Federated States of Micronesia (FSM) 2003 - 2022

Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet Labs, and

Results from additional dynamic cone penetration testing of soils on the Utuado Batholith, upland and dissected terrains, Puerto Rico - June 2022

A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values alongside 12 soil pits dug in the Utuado Batholith, a late Cretaceous age granodiorite pluton located on the northern portion of the

Field observations of landslides and related materials following Hurricane Maria, Puerto Rico

During September 2017, Hurricane Maria caused widespread landsliding throughout mountainous regions of Puerto Rico, with more than 71,000 landslides being subsequently identified from aerial imagery (Hughes et al., 2019). Most landslides apparently mobilized as debris flows and occurred within soil (unconsolidated material overlying saprolite and bedrock) and saprolite overlying less-weathered roc

Multi-stage soil-hydraulic recovery and limited ravel accumulations following the 2017 Nuns and Tubbs wildfires in Northern California

Wildfire can impact soil-hydraulic properties by reducing saturated hydraulic conductivity and sorptivity, making recently burned landscapes prone to debris flows and flash floods. The post-fire hazard window can range from years to decades. In Northern California, where wildfire frequency is steadily increasing, the impact and soil-hydraulic recovery from wildfires is unknown.

Sediment budget for watersheds of West Maui, Hawaii

Episodic runoff brings suspended sediment to West Maui’s nearshore waters, turning them from blue to brown. This pollution degrades the ecological, cultural, and recreational value of these iconic nearshore waters. We used mapping, monitoring, and modeling to identify and quantify the watershed sources for fine sediment that pollutes the nearshore each year. These results focus strategies to reduc

Landslides triggered by Hurricane Maria: Assessment of an extreme event in Puerto Rico

Hurricane Maria hit the island of Puerto Rico on 20 September 2017 and triggered more than 40,000 landslides in at least three-fourths of Puerto Rico’s 78 municipalities. The number of landslides that occurred during this event was two orders of magnitude greater than those reported from previous hurricanes.
