An article from the Red Cross. Excerpt from the article about finding people and helping:
To respond to the needs of those concerned about relatives in the affected regions International Committee of the Red Cross (ICRC) is encouraging those living overseas to make use of its restoring family links web page: www.icrc.org/familylinks.
Those who want to help can go to www.redcross.org and donate to Japan Earthquake and Pacific Tsunami. People can also text REDCROSS to 90999 to make a $10 donation to help those affected by the earthquake in Japan and tsunami throughout the Pacific.
I donated a little bit of money last night. My iron has been too low to donate blood (the last three times I went, all I got to show for it was a pricked finger -_-), but I'm going to sign up to try again.
The people of Japan are resilient and they will get through this.
