I am no longer going to update the How to Help post
here - it is already time consuming trying to keep the post at TCP updated. Please check this post at TCP
for ways to help - the list is constantly being updated and includes local as well as national agencies, in addition to smaller charities and organizations that are starting relief efforts. Also listed are numbers to call if you or anyone you know is searching for friends or relatives missing in the area.
Tsunami Help Blog
has been a tremendous source of links, news and charities, as well as emergency phone numbers.
