WHAT A NATURAL DISASTER IS?

A Natural disaster is a major adverse event resulting from natural processes of or effecting the Earth, for example floods, tsunami, tornadoes, hurricanes and cyclones, volcanic eruptions, earthquakes, heat waves and droughts, wild fires, landslides, blizzards, ice astorms and avalanches. A natural disaster can include loss of life, injury, economic loss, and environmental loss. The severity of the losses depends on the ability of the affected population to resist the hazard, also called their resilience.

 Thus an event will not constitute a natural disaster if it occurs in an area without vulnerability, e.g. an earthquake in an uninhabited area. The term natural has consequently been disputed because the events are not purely natural but result from interaction between natural forces and humanity. A concrete example of the division between a natural hazard and a natural disaster is that the 1906 San Francisco earthquake was a disaster, whereas earthquakes are a hazard.

FIRST PART OF THE PROJECT

NATURAL DISASTERS

MEMBERS OF THE GROUP:

Maria Clara Puerta Correa

Luisa María Tangarife García

María Paulina Salcedo Cardona

TOPIC:  Natural disasters

WHAT YOU ARE GOING TO DO? : We are going to do a newscast.

WHO IS DOING WHAT?

Luisa is going to be the interviewer.  She is going to begin saying what a natural disaster is, and she is going to present the experts on the subject, Maria Clara and Maria Paulina, they are going to explain more about the topic.

Luisa is going to ask Maria Paulina about some common natural disasters like tsunamis, and she is going to answer what is it, causes and effects.

Luisa is going to ask the same question to Maria Clara, but in this case, about hurricanes, and then Luisa is going to describe the earthquakes.

Luisa is going to introduce the video of the top 10 infamous natural disasters of the last 100 years, and then we are going to present the video. Later we are going to say more interesting information about the five infamous natural disasters.

Finally Maria Clara is going to explain how we can to prevent the natural disasters.
