Additionally, if a tectonic event oocurs in a tropical climate, disease will spread much quicker. Due to the chaos caused by disasters such as earthquakes, tsunami's and volcanic eruptions, evacuees stay in shelters therefore are very close to each other with a lack of sanitation and so disease spreads much quicker and can add to the death toll. In Haiti, a few months after a devastating earthquake, a cholera outbreak started in a UN peacekeeping camp due to poor sanitation causing sewage to enter a waterway. This consequently killed around 8,183 of people. This shows how easy disease can spread as a result of a natural disaster, and shows how deadly tectonic events can be.
