Knowledge, attitude and practices of coastal communities in Trinidad and Tobago about tsunamis

Tsunamis are natural hazards that have captured the attention of the international community due to the devastating impacts that they can have on humans and the built and natural environment. These natural events may be caused by (i) earthquakes that occur below or near the ocean floor, (ii) volcanic eruptions, (iii) submarine landslides and, (iv) coastal rock falls. In the past, these natural hazards have resulted in the loss of human lives, the destruction of infrastructure, coastal flooding, environmental damage and economic loss.

The Caribbean is one of the regions of the world where tsunamis are a reality in that these natural hazards have occurred in the region in the past and could occur in the future. For example, a tsunami can be generated in the southern Caribbean if (i) Kick ‘em Jenny (a submarine volcano located just north of Grenada) erupts or (ii) an earthquake with the relevant characteristics occurs.

Trinidad and Tobago are the most southerly islands in the Caribbean archipelago and has a percentage of its population living in low-lying coastal regions on both islands. Yet, are we as a country prepared for such a natural hazard? Do coastal communities know some of the warning signs and action that should be taken in certain scenarios? Disaster preparedness and awareness is a critical component in mitigating the potentially devastating impact of tsunamis. In 2014, under the supervision of the late Professor Dave Chadee, I led a team of volunteers and conducted a survey in coastal communities across Trinidad and Tobago to determine their knowledge, attitude and practices about tsunamis.
