Devastation beyond the storm: Hurricane Ian the latest disaster to cause increase in suicides

Sep 28, 2023

This week marks one year since Hurricane Ian decimated towns along Florida's Gulf Coast, erasing whole neighborhoods and claiming 160 lives. Recent research found that the toll could continue to rise.

The Tampa Bay Times reported that six people have taken their lives since the Category 5 storm moved on from the area. Increases in the number of suicides after a disaster is sadly not an uncommon occurrence, according to research by the University of Delaware's Jennifer Horney, professor founding director of UD's epidemiology program.

According to a study led by Horney in The Journal of Crisis Intervention and Suicide Prevention, suicide rates increased 23% when comparing the three-year period preceding a disaster to three years after an event.

For all disaster types combined as well as individually for severe storms, flooding and ice storms, researchers found the suicide rate increased in both the first and second year following a disaster, then declined in the third year.

Flooding saw suicide rates increase by nearly 18% the first year and 61% the second year before declining to the baseline rate after that.

By contrast, the suicide rate following hurricanes rose in the first year — jumping 26% — then returned to the baseline in the second year. “Counties impacted by hurricanes saw the biggest increase in the rate of suicide in the first year, which makes sense because it's the most widespread type of disaster among those we examined,” Horney said.

Horney's research focuses on the impacts of natural disasters on public health, as well as linkages between disaster planning and the actions communities and individuals take to prepare, respond and recover.

Experts on earthquake response, community recovery and building safety

The shaking from a major earthquake may be over in minutes, but its consequences will last for years. University of Delaware experts can address emergency response, distributing aid, assessing damaged buildings, helping vulnerable communities and planning for long-term recovery. Their expertise is particularly relevant as communities across Latin America respond to major earthquakes, including the deadly magnitude 7.4 earthquake in Colombia. Tricia Wachtendorf, co-director of UD’s Disaster Research Center, offers expertise on how governments, nonprofits, emergency responders and community groups coordinate following a major disaster. Her research examines the role of spontaneous or “emergent” groups, humanitarian aid and donations, and how communities and organizations respond in the aftermath of disasters. Jennifer Trivedi, associate professor of anthropology and Disaster Research Center faculty member, specializes in disaster vulnerability and why some communities are more severely affected than others. She also addresses the long-term recovery needs and planning that emerge after the immediate crisis. Michael Chajes, professor of civil and environmental engineering, provides expertise on the structural damage caused by earthquakes, why some buildings collapse while others withstand the shaking and how engineers assess damaged structures and improve earthquake resilience.

Mapping the ancient world with underwater robotics

As audiences flock to theaters for Christopher Nolan's The Odyssey, University of Delaware professor Art Trembanis is leading a real-life expedition to uncover one of ancient Greece's most important maritime landscapes. Trembanis, a professor in UD's School of Marine Science and Policy and an expert in seafloor mapping, marine robotics and underwater sensing technologies, recently led a team of students and researchers to the ancient harbor of Kenchreai, where they deployed autonomous underwater vehicles, advanced sonar systems and other cutting-edge mapping technologies to document a harbor that has remained hidden beneath the Mediterranean Sea for centuries. The expedition collected geospatial data that will allow researchers to reconstruct the ancient port in remarkable detail and ultimately create a "digital twin" of the site. The virtual model will enable archaeologists, engineers, students and the public to explore the harbor as if the water had been removed, preserving an invaluable piece of cultural heritage while advancing the use of marine technology in archaeology. Trembanis can discuss: Marine robotics and autonomous underwater vehicles Seafloor mapping and underwater imaging technologies The use of digital twins and 3D modeling to study underwater environments Advances in marine geospatial technology and ocean exploration Underwater archaeology and documenting submerged cultural heritage How engineering and marine science are transforming the study of oceans and ancient landscapes The role of emerging technologies in scientific discovery and education To arrange an interview with Trembanis, click on his profile or email mediarelations@udel.edu.

How Wildfires Impact Vulnerable Communities, Pets and Public Health Systems

Wildfires burning across the world, now in parts of France and Spain, are forcing hundreds of thousands of people to evacuate. University of Delaware experts are available to discuss wildfire evacuations, vulnerable communities, animal rescue and the health effects of wildfire smoke exposure. Those experts, from UD’s Disaster Research Center, include: Sarah DeYoung Professor of sociology and criminal justice: • How people are forced to make split-second decisions involving horses, livestock and companion animals during fast-moving wildfires. • Why some owners must turn animals loose when evacuation time is limited. • Lessons from past disasters and animal rescue research. Jennifer Trivedi Assistant professor of anthropology: • The unique challenges faced by vulnerable populations during wildfires. • Complications surrounding evacuation decision-making and evacuation needs. • Long-term recovery following catastrophic disasters. Jennifer Horney Chair of UD’s Department of Epidemiology: • Health risks associated with wildfire smoke exposure, including respiratory infections. • How wildfire smoke and airborne pollutants affect population health. • The strain major wildfires can place on public health and health care systems.
