The reason why a serious natural disaster such as a flood, famine, or earthquake might lead to migration is that people might need to migrate to rebuild their lives.
How do natural disasters affect migration?
When there is a natural disaster such as a flood, famine, or earthquake people tend to lose their belongings as well as their lives.
