Here are some charities taking online and / or phone donations. I have not investigated efficiency of all these charities yet (as a policy, I do not donate to charities unless at least 70% of my donations reach the victims. Some charities have huge "administrative costs" where most of your contributions end up in forms of salaries and advertisement. Sad but true).

I am personally going with Doctors Without Borders.
