Natural disasters can severely injure or kill people and cause immense property damage. In 2010, natural disasters killed 295,000 people and cost insurers $218 billion globally. The 2011 Tsunami and earthquake in Japan killed over 10,000 people, while Hurricane Katrina in 2005 alone caused $81 billion in property damage to New Orleans, flooding 80% of the city under 15 feet of water and reducing the city's population. While natural disasters cannot be prevented, organizations help with relief efforts, rebuilding, and preparing for aftermaths that can include landslides and fires.
