Floods, tsunamis, earthquakes and hurricanes can create threats to human security and have long-lasting effects on individuals, communities, and countries. Though a natural disaster is not an act of war, nor is it one state invading another, the devastation in the aftermath of an earthquake
can destroy security for hundreds of thousands of people.
Homelessness, disease, and displacement can all be a direct result of a natural disaster. Such disasters threaten a local community but also the neighboring community. Security, then, is more than merely the absence of conflict.
A United Nations University article by Futamura (2011) Bottom of Formreflects on the Indian Ocean Tsunami of 2004, Hurricane Katrina in 2005, the Haiti earthquakes in 2010, and earthquakes and tsunamis in east Japan during 2011. These natural disasters hurt the local community and threatened the security of the community and the affected states.
