Natural disaster-proof suits

As part of our Active Planet topic we have been learning about different natural disasters such as earthquakes, volcanoes, tsunamis and floods. We designed natural disaster-proof suits to keep people safe in a natural disaster. These included oxygen tanks for breathing under water, jet-packs for flying away from danger and special armour to protect people from falling rocks. If you were going to create a natural disaster-proof suit, which features would it include? Why?
