Slashdot has a couple of posts here and here that follow the recent post on huge earthquake and tsunami in Asia.
Many high traffic sites, such as Google and Amazon link from their front pages to information for those who wish to donate. There is also more information and coverage at tsunamihelp.blogspot.com/.
If you want to get a better idea of what happened, than watch the videos from this site and this site. I have mirrored them for your convenience.
