Family links network
If you're looking for someone missing in the Philippines, or if you have information about someone there, you can reach out to the ICRC restoring family links network: familylinks.icrc.org/en/pages/home.aspx
A Google crisis map has also been added to detail areas designated for relief. This is a crowdsourced map of evacuation centers, crisis areas, and relief drop zone areas in relation to Typhoon Haiyan.
