What Effects Do Tsunamis Have on People?

Tsunamis have numerous negative impacts on people: they cause illness and injury, even death, cause homelessness and job loss and destroy infrastructure in human communities. Tsunamis pose short-term and long-term threats to economies and human health. They often contaminate food and water supplies, cripple power lines and cause damage by bringing debris into homes.

In the short term, tsunamis bring the risk of traumatic injuries and infections, as people suffer injuries from moving debris and sustain lacerations. Risk of disease outbreaks, along with food-borne and water-borne illnesses, rise after tsunami exposure. Tsunamis damage land and infrastructure, rendering businesses incapable of production and paralyzing agricultural operations, in turn reducing economic vitality in affected areas.
