Carnival Corp owner Micky Arison and his wife Madeleine are donating $5m to help global disaster relief efforts.
The family's charitable foundation will give cash to Save the Children and Direct Relief to support urgent hurricane, typhoon, earthquake and tsunami emergency work in North and South Carolina, the Philippines and Indonesia.
Carnival Foundation and the group's cruise line brands also have fundraising initiatives under way to provide additional support to multiple organisations leading immediate relief efforts in affected areas.
