A natural disaster is a major adverse event created by natural processes. Most frequently occurring natural disasters are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis and avalanches. Different places in the world normally suffer from different types of disasters; depending on localization and climate. WFET consider that all disasters have three stages we need to consider: before -, during – and after the disaster. Every stage is distinct and has its specific challenges; calling for worse case preparation, survival techniques and a lot of rescue training. WFET focuses on preparing people in emergency tactics. Let us go, through some disasters that might happen to understand the complexity.
