Jenny Ramirez Coauthored a Paper on the Geotechnical and Social Impacts of the 2021 Nippes, Haiti, Earthquake in Bulletin of the Seismological Society of America

Jenny Ramirez, Ph.D. (Ontario) coauthored the paper "Intersectional Impacts of the 2021 Mw 7.2 Nippes, Haiti, Earthquake from Geotechnical and Social Perspectives" in the Bulletin of the Seismological Society on January 4, 2023.

Jenny's coauthors were Ashly Cabas, Cristina Lorenzo-Velazquez, Nancy Ingabire Abayo, and Chunyang Ji (North Carolina State University), Fernando E. Garcia (University of Michigan), Joanne Pérodin (Florida International University), Yu-Wei Hwang (National Yang Ming Chiao Tung University), Shideh Dashti (University of Colorado Boulder), Nazife Emel Ganapati (Department of Public Policy and Administration Steven J. Green School of International and Public Affairs), Sary Nicolas (Lanagan Engineering), Michael R.Z. Whitworth (AECOM), Kelly Guerrier and Newdeskarl Saint Fleur (Université d'État d'Haïti), Santina Contreras (University of South California), Richard Lagesse (ARUP), Louis Herns Marcelin (University of Miami), and Christa L. Remington (University of South Florida).

Jenny is a Project Professional whose experience includes site characterization, data visualization, and numerical modeling. She addresses geotechnical-engineering-related problems and helps design and assess dams, landfills, disposal containment facilities, and other earth structures. Her experience also includes task automation, geotechnical instrumentation interpretation, seismic response analyses, analyses of liquefiable soils, forensic analyses, and reconnaissance evaluations after extreme natural disaster. Jenny is active member of the Geotechnical Extreme Event Reconnaissance Team, and as such, as performed site reconnaissance after major natural events to identify failure triggering and disaster consequences.

The Bulletin of the Seismological Society of America publishes both original papers that advance the understanding of seismology and seismic hazard analyses and review articles that summarize important research topics. The Bulletin's format allows papers to fully explore research topics in detail.

The Seismological Society of America (SSA) was born in the aftershocks of the 1906 San Francisco earthquake, at a time when engineers, mathematicians, and geologists united to learn more about the devastating event. The SSA is committed to advancing seismology and sharing research with the public to help build an earthquake-aware world.


The Mw 7.2 Nippes, Haiti, earthquake occurred on August 14, 2021 in Haiti's southwest peninsula and in the midst of significant social, economic, and political crises. A hybrid reconnaissance mission (i.e., combined remote and field investigation) was coordinated to document damage to the built environment after the event. This article evaluates two ground‐motion records available in Haiti in the context of the geology of the region and known areas with significant damage, such as Les Cayes. We also present a new map of time‐averaged shear‐wave velocity values to 30m depth (⁠Vs30⁠) for Les Cayes and Port‐au‐Prince based on the geostatistical approach of kriging and accounting for region‐specific geology proxies and field measurements of Vs30⁠. Case studies of ground failure observations, including landslides and liquefaction triggering, are described as well as the intersection of social and engineering observations. Maps depicting this important intersection are provided to facilitate the assessment of how natural hazards and social conflicts have influenced the vulnerability of Haiti's population to earthquakes.
