A deadly tsunami struck Indonesia on Saturday, killing at least 373 people and injuring more than 1,459 others.

Rescuers were searching for survivors in Indonesia’s Sunda Strait. It has been a devastating year for the country, which has seen a strong earthquake and tsunami, an airline crash and fires that together have killed more than 4,500 people, the most in more than a decade.

Nonprofit organizations and charities have mobilized to bring relief to those people affected by the tsunami. If you want to help, here are some pointers and a list of some of those organizations.

Experts say sending money is usually the most efficient way to help in a disaster. Sending goods like canned and dry food may be helpful, but there is always a chance that they might be misplaced or forgotten. They could also take longer to get to those in need.
