The Church of Jesus Christ of Latter-Day Saints has a Humanitarian Foundation that anyone can contribute to. 100% of the aid goes to the victims. If the LDS Church doesn't have a presence in the afflicted country(s), then they work with the Catholic Relief Services. You can make donations at
Humanitarian Relief Services. The nice thing about the Humanitarian Services foundation is that one can donate money or products to them at any time for help anywhere around the world, including the United States.
